DEV控件：gridControl常用属性设置

1.隐藏最上面的GroupPanel

gridView1.OptionsView.ShowGroupPanel=false;

2.得到当前选定记录某字段的值

sValue=Table.Rows[gridView1.FocusedRowHandle][FieldName].ToString();

3.数据只读

gridView1.OptionsBehavior.Editable=false;

4.不显示MasterDetailView

gridView1.OptionsDetail.EnableMasterViewMode=false;

5.修改最上面的GroupPanel内容

gridView1.GroupPanelText="电子灵魂";

6.设置数据源:

gridControl1.DataSource = dt;绑定每一列的FiledName--属性对于Oracle数据库,所有的在设计器里写的程序中的字段名必须大写,否则可能绑定不上字段,sqlserver没有这个限制.

7.读写拷贝权限设置

只读不可拷贝：

ColumnViewOptionsBehavior.Editable = False

只读可拷贝:

ColumnViewOptionsBehavior.Editable = TrueOptionsColumn.AllowEdit = TrueOptionsColumn.ReadOnly = True

可编辑:

ColumnViewOptionsBehavior.Editable = TrueOptionsColumn.AllowEdit = TrueOptionsColumn.ReadOnly = False

8.模板列的设置:

到Columns中，在他的属性中找到ColumnEdit.

以LookUpEdit为例：

首先从Designer左边菜单In-PlaceEditor Repository中添加LookUpEdit.取名为Re1.然后.在他的Columns属性中添加3列.Caption依次为:编号,姓名,性别.FieldName依次为:FID,FNAME,FSEX.然后将Re1的NullText设置成空.

　　AutoSearchColumnIndex属性设置为2.ImmediatePopup属性设置为True.

　　SearchMode设置为OnlyInPopup.

　　然后将这个模板列附加到我们上面提到的列1(也就是将列1的ColumnEdit属性设成Re1)

　　最后我们还要在代码里面给Re1绑定数据源和显示项.

Re1.DataSource =DALUse.Query("select fid,fname,fsex from dual").Tables[0];Re1.DisplayMember ="FSEX";Re1.ValueMember ="FNAME";

9.设某一列文字和标题局中显示

gridView1.Columns[0].AppearanceHeader.TextOptions.HAlignment =DevExpress.Utils.HorzAlignment.Center;gridView1.Columns[0].AppearanceCell.TextOptions.HAlignment =DevExpress.Utils.HorzAlignment.Center;

10.去掉某一列上面的自动筛选功能(Filter)

gridView1.Columns[0].OptionsFilter.AllowAutoFilter = false;gridView1.Columns[0].OptionsFilter.AllowFilter =false;              gridView1.Columns[0].OptionsFilter.ImmediateUpdateAutoFilter =false;

11.设置冻结列(左冻结)

gridView1.Columns[0].Fixed= DevExpress.XtraGrid.Columns.FixedStyle.Left;

12.得到单元格数据(0行0列)

string ss=gridView1.GetRowCellDisplayText(0,gridView1.Columns[0]);string ss = gridView1.GetRowCellValue(0, gridView1.Columns[0]);

13.设置单元格数据(将0行0列的单元格赋值123)

gridView1.SetRowCellValue(0, gridView1.Columns[0],"123");

13.手动添加dev的列

DevExpress.XtraGrid.Columns.GridColumn Col1=newDevExpress.XtraGrid.Columns.GridColumn ();Col1.FieldName="FID";Col1.Visible=true;Col1.VisibleIndex=gridView1.Columns.Count;gridView1.Columns.Add(Col1);

14.设置自动增加的行号,需要先添加给gridview添加事件CustomDrawRowIndicator

private void gridview_CustomDrawRowIndicator(objectsender,DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e){if (e.Info.IsRowIndicator &&e.RowHandle >= 0)e.Info.DisplayText = (e.RowHandle + 1).ToString();}

15.删除: (修改了dgvdel里的datagridviewdel方法)

public static voiddatagridviewdel_Dev(DevExpress.XtraGrid.Views.Grid.GridView Mydgv){if (MessageBox.Show("你确定要删除选中的记录吗？", "删除提示",MessageBoxButtons.YesNo, MessageBoxIcon.Warning, MessageBoxDefaultButton.Button2, 0, false) == DialogResult.Yes){intiSelectRowCount = Mydgv.SelectedRowsCount;if(iSelectRowCount > 0){Mydgv.DeleteSelectedRows();}}}

16. 新增: (对于新增,其本身的AddNewRow方法就可以做到)

private void btn_add_Click(object sender, EventArgs e){ gridView1.AddNewRow();  }具体如果对于新加行还有什么特别的设置,可以在它gridView1_InitNewRow事件中填写:private void gridView1_InitNewRow(object sender,DevExpress.XtraGrid.Views.Grid.InitNewRowEventArgs e){ColumnView View = sender as ColumnView;View.SetRowCellValue(e.RowHandle,View.Columns[0],gridView1.GetRowCellValue(gridView1.GetRowHandle(gridView1.RowCount - 2),gridView1.Columns[0])); //复制最后一行的数据到新行
 View.SetRowCellValue(e.RowHandle, View.Columns[1],gridView1.GetRowCellValue(gridView1.GetRowHandle(gridView1.RowCount - 2),gridView1.Columns[1])); //复制最后一行的数据到新行
 }

17. 保存 (第三方控件提供的RefreshData和RefreshDataSource方法对于保存数据都不好使,最后还是使用了Dgvsave的datagridviewsave方法,用这个方法就可以)

18.特效：gridcontrol中有5种view 型式，普通的是gridview，然后分别为cardview、BandedView、AdvancedBandedView、LayoutView；共5种。

1）、view组中把OptionView下的viewmode 设置成“Carousel”就达到这种“旋转木马”式的gridcontrolview 特效了

2）、layoutView1.OptionsCarouselMode.PitchAngle 这个属性决定“旋转木马”的pitch angle 螺距角; 螺旋角; 螺旋升角; 俯仰角; 倾角; 节锥半角

3）、Roll Angle 属性决定着倾侧角度

4）、指定数据源，显示数据：

//显示数据private voidshowData(List<Employee > list){DataTable dt= new DataTable("OneEmployee");dt.Columns.Add("Caption", System.Type.GetType("System.String"));dt.Columns.Add("Department",System.Type.GetType("System.String"));dt.Columns.Add("PhotoName",System.Type.GetType("System.Byte[]"));for(int i = 0; i < list.Count; i++){DataRow dr = dt.NewRow();dr["Caption"] = list[i].Name;dr["Department"] = list[i].Department;string imagePath = @"D:\C#\photos\" + list[i].PhotoPath;dr["PhotoName"] = getImageByte(imagePath);dt.Rows.Add(dr);}gridControl1.DataSource = dt;}//返回图片的字节流byte[]private byte[] getImageByte(stringimagePath){FileStreamfiles = new FileStream(imagePath, FileMode.Open);byte[]imgByte = new byte [files.Length ];files.Read(imgByte, 0, imgByte.Length);files.Close();returnimgByte;}

19.检查数据的有效性

在gridview的ValidateRow事件中加入检查代码：

#region 检查数据private void gridView1_ValidateRow(object sender, ValidateRowEventArgse){GridView view = sender as GridView;view.ClearColumnErrors();if (view.GetRowCellValue(e.RowHandle, "ReceiveDate") ==DBNull.Value){e.Valid = false;view.SetColumnError(view.Columns["ReceiveDate"], "必须指定日期");}}#endregion

调用gridview.UpdateCurrentRow()方法执行检查

最常用的DevExpress Winform 4个代码片段：

一、GridControl的删除操作

private void rILinkEditInfoDel_Click(object sender, EventArgs e){if (XtraMessageBox.Show("请确定是否删除当前记录？", "警告",MessageBoxButtons.YesNo, MessageBoxIcon.Warning) == DialogResult.Yes){DataRow row =gvInfos.GetDataRow(gvInfos.FocusedRowHandle);delByCode(row["Code"].ToString());XtraMessageBox.Show("操作成功！");}}

二、绑定非数据表中列

Hashtable ht = new Hashtable();private void gridView6_CustomUnboundColumnData(object sender, DevExpress.XtraGrid.Views.Base.CustomColumnDataEventArgse){GridView View = sender as GridView;if (e.RowHandle >= 0){object needAlert =View.GetRowCellValue(e.RowHandle, View.Columns["needAlert"]);if (needAlert != null &needAlert != DBNull.Value && needAlert.ToString().Trim() !="0" & View.GetRowCellValue(e.RowHandle,View.Columns["Value"]) != DBNull.Value){decimal AverValue = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle,View.Columns["Value"]));objectMinValue = View.GetRowCellValue(e.RowHandle,View.Columns["MinValue"]);objectMaxVlaue = View.GetRowCellValue(e.RowHandle,View.Columns["MaxValue"]);if(MinValue != DBNull.Value & MinValue != null & MaxVlaue.ToString() !="" & MaxVlaue != DBNull.Value && MaxVlaue != null &MaxVlaue.ToString() != ""){decimal gridColumn2 = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle,View.Columns["MinValue"]));decimal gridColumn1 = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle,View.Columns["MaxValue"]));if (gridColumn2 > AverValue || AverValue > gridColumn1){if (!ht.ContainsKey("pic"))ht.Add("pic", GetImage(1));e.Value = ht["pic"];}}}}}/// <summary>/// 由资源文件获取图片
/// </summary>/// <param name="key"></param>/// <returns></returns>byte[] GetImage(int key){Image img =DevExpress.Utils.Controls.ImageHelper.CreateImageFromResources(string.Format("RiverSys.Resources.{0}.gif",key.ToString()), typeof(RiverInfos).Assembly);returnDevExpress.XtraEditors.Controls.ByteImageConverter.ToByteArray(img,ImageFormat.Gif);}

/// <summary>/// 动态根据条件设置行样式
/// </summary>/// <param name="sender"></param>/// <param name="e"></param>private void gridView6_RowStyle(object sender,DevExpress.XtraGrid.Views.Grid.RowStyleEventArgs e){GridView View = sender as GridView;if (e.RowHandle >= 0){object needAlert =View.GetRowCellValue(e.RowHandle, View.Columns["needAlert"]);if (needAlert != null &needAlert != DBNull.Value && needAlert.ToString().Trim() !="0" & View.GetRowCellValue(e.RowHandle,View.Columns["Value"]) != DBNull.Value){decimal AverValue = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.Columns["Value"]));objectMinValue = View.GetRowCellValue(e.RowHandle,View.Columns["MinValue"]);objectMaxVlaue = View.GetRowCellValue(e.RowHandle,View.Columns["MaxValue"]);if(MinValue != DBNull.Value & MinValue != null & MaxVlaue.ToString() !="" & MaxVlaue != DBNull.Value && MaxVlaue != null &MaxVlaue.ToString() != ""){decimal gridColumn2 = Convert.ToDecimal(MinValue);decimal gridColumn1 = Convert.ToDecimal(MaxVlaue);if (gridColumn2 > AverValue || AverValue > gridColumn1){e.Appearance.ForeColor = Color.Red;e.Appearance.BackColor = Color.LightGray;}}}}}

三、GridControl 中颜色选择控件

private void gvMapColor_CustomUnboundColumnData(object sender,DevExpress.XtraGrid.Views.Base.CustomColumnDataEventArgs e){GridView view = sender as GridView;DataView dv = view.DataSource as DataView;if (e.IsGetData){string strVal =dv[e.ListSourceRowIndex]["Color"].ToString();if (strVal != ""){//e.Value = DevExpress.Utils.StyleLayout.ColorFromString(strVal);e.Value = Common.HexToColor(strVal);}}else{//Color colorVal =DevExpress.Utils.StyleLayout.ColorFromString(e.Value.ToString());Color colorVal =(Color)e.Value;dv[e.ListSourceRowIndex]["Color"] =Common.RGB_HEX(colorVal.ToArgb());}}

四、关于 GridControl 验证示例

/**//// <summary>/// 初始化GridView，绑定数据
/// </summary>/// <param name="parentId"></param>private void GridViewBindData(string parentId){this.gridView1.Columns.Clear();this.FDs= areaSetupActionHelper.getDsRegionByParentId(parentId);this.gridCArea.DataSource =this.FDs.Tables[0].DefaultView;this.gridView1.Columns["id"].VisibleIndex =-1;this.gridView1.Columns["childCounts"].VisibleIndex= -1;this.gridView1.Columns["reg_id"].Caption ="区划编号";this.gridView1.Columns["reg_name"].Caption ="区划名称";this.gridView1.Columns["parent_id"].Caption ="父区划编号";this.gridView1.Columns["reg_desc"].Caption ="区划描述";this.gridView1.Columns["parent_id"].ImageIndex =1;this.gridView1.Columns["reg_desc"].ImageIndex = 0;RepositoryItemTextEdit textEditReg_Id = newRepositoryItemTextEdit();textEditReg_Id.Mask.EditMask =parentId+"\\d{2,3}";textEditReg_Id.Mask.MaskType =DevExpress.XtraEditors.Mask.MaskType.Regular;this.gridView1.Columns["reg_id"].ColumnEdit =textEditReg_Id;this.gridView1.Columns["reg_desc"].ColumnEdit= new RepositoryItemMemoExEdit();TreeListNode node =this.treelArea.FocusedNode.ParentNode;string fid =node==null?"0":node.GetValue("RegID").ToString().Trim();DataSet ds =areaSetupActionHelper.getDsRegionByParentId(fid);RepositoryItemLookUpEdit lookUEParent_Id = newRepositoryItemLookUpEdit();lookUEParent_Id.Columns.Add(newLookUpColumnInfo("reg_id", 40, "区划编号"));lookUEParent_Id.Columns.Add(newLookUpColumnInfo("reg_name", 40, "区划名称"));lookUEParent_Id.DataSource = ds.Tables[0].DefaultView;lookUEParent_Id.ValueMember = "reg_id";lookUEParent_Id.DisplayMember = "reg_id";this.gridView1.Columns["parent_id"].ColumnEdit =lookUEParent_Id;}

/**//// <summary>/// gridView单元格验证的相关处理程序

9、如何显示水平滚动条？或

设置 this.gridView.OptionsView.ColumnAutoWidth = false;

.....列表宽度自适应内容

gridview1.BestFitColumns();

10、如何定位到第一条数据/记录？

设置 this.gridView.MoveFirst()

11、如何定位到下一条数据/记录？
设置 this.gridView.MoveNext()

12、如何定位到最后一条数据/记录？

设置 this.gridView.MoveLast()

13、设置成一次选择一行，并且不能被编辑

this.gridView1.FocusRectStyle = DevExpress.XtraGrid.Views.Grid.DrawFocusRectStyle.RowFocus;
this.gridView1.OptionsBehavior.Editable = false;
this.gridView1.OptionsSelection.EnableAppearanceFocusedCell = false;

14、如何显示行号？

private void gvPayList_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e){e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far;if (e.Info.IsRowIndicator){if (e.RowHandle >= 0){e.Info.DisplayText = (e.RowHandle + 1).ToString();}else if (e.RowHandle < 0 && e.RowHandle > -1000){e.Info.Appearance.BackColor = System.Drawing.Color.AntiqueWhite;e.Info.DisplayText = "G" + e.RowHandle.ToString();}}}

15、如何让各列头禁止移动？

设置 gridView1.OptionsCustomization.AllowColumnMoving = false;

16、如何让各列头禁止排序？

设置 gridView1.OptionsCustomization.AllowSort = false;

17、如何禁止各列头改变列宽？

设置 gridView1.OptionsCustomization.AllowColumnResizing = false;

18.拖动滚动条时固定某一列

设置Columns，选择要固定的列。设置Fixed属性，可以选择：固定在左边、固定在右边、不固定。

19.获取选定行,指定列单元格的内容

return gridView1.GetRowCellValue(pRows[0], ColumName).ToString ();

20.分组显示

OptionsView>OptionsBehavior>AutoExpandAllGroups = True
选择要分组的列，将GroupIndex属性设置为0

21.格式化数据

private void gvList_ValidatingEditor(object sender, DevExpress.XtraEditors.Controls.BaseContainerValidateEditorEventArgs e){if (this.gvList.FocusedColumn.FieldName == "passQty"){string passQty = e.Value.ToString().Trim();int receiveQty = orderDetailList[this.gvList.FocusedRowHandle].qty;if (!JXType.IsIntBigThanZero(passQty)){e.Valid = false;e.ErrorText = "合格数量必须为大于等于0小于等于接货数量的整数！";}else{if (int.Parse(passQty) > receiveQty){e.Valid = false;e.ErrorText = "合格数量必须为大于0小于等于接货数量的整数！";}}}}

22.合并表头

///初始化表格using DevExpress.XtraGrid.Columns;
using DevExpress.XtraGrid.Views.Base;
using DevExpress.XtraGrid.Views.BandedGrid;
using DevExpress.XtraEditors.Repository;private void InitGrid(){// advBandedGridView1是表格上的默认视图，注意这里声明的是：BandedGridViewBandedGridView view = advBandedGridView1 as BandedGridView;view.BeginUpdate(); //开始视图的编辑，防止触发其他事件view.BeginDataUpdate(); //开始数据的编辑
            view.Bands.Clear();view.OptionsView.ShowColumnHeaders = false;                         //因为有Band列了，所以把ColumnHeader隐藏//添加列标题//添加列标题GridBand bandID = view.Bands.AddBand("ID");bandID.Visible = false; //隐藏ID列GridBand bandName = view.Bands.AddBand("姓名");GridBand bandSex = view.Bands.AddBand("性别");GridBand bandBirth = view.Bands.AddBand("出生日期");GridBand bandScore = view.Bands.AddBand("分数");GridBand bandMath = bandScore.Children.AddBand("数学");GridBand bandChinese = bandScore.Children.AddBand("语文");GridBand bandEnglish = bandScore.Children.AddBand("英语");GridBand bandSubTotal = bandScore.Children.AddBand("小计");GridBand bandRemark = view.Bands.AddBand("备注");bandFile.AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;//这是合并表头居中显示view.EndDataUpdate();//结束数据的编辑view.EndUpdate();   //结束视图的编辑}

具体可看

dev gridcontrol 合并表头

23. //动态添加列

DevExpress.XtraGrid.Columns.GridColumn Col1 = new DevExpress.XtraGrid.Columns.GridColumn();Col1.FieldName = "name";Col1.Caption = "名字";Col1.Visible = false;Col1.VisibleIndex = gvCountry.Columns.Count;gvCountry.Columns.Add(Col1);

24。设置自动增加的行号

private void gridview_CustomDrawRowIndicator(object sender,DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e){e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far;if (e.Info.IsRowIndicator){if (e.RowHandle >= 0){e.Info.DisplayText = (e.RowHandle + 1).ToString();}else if (e.RowHandle < 0 && e.RowHandle > -1000){e.Info.Appearance.BackColor = System.Drawing.Color.AntiqueWhite;e.Info.DisplayText = "G" + e.RowHandle.ToString();}}｝

25.特效：gridcontrol中有5种view 型式，普通的是gridview，然后分别为cardview、BandedView、Advanced BandedView、LayoutView；共5种。

1）、view组中把OptionView下的viewmode 设置成“Carousel”就达到这种“旋转木马”式的gridcontrol view 特效了
2）、layoutView1.OptionsCarouselMode.PitchAngle 这个属性决定“旋转木马”的pitch angle 螺距角; 螺旋角; 螺旋升角; 俯仰角; 倾角; 节锥半角
3）、Roll Angle 属性决定着倾侧角度
4）、指定数据源，显示数据：

//显示数据private void showData(List<Employee > list){DataTable dt = new DataTable("OneEmployee");dt.Columns.Add("Caption", System.Type.GetType("System.String"));dt.Columns.Add("Department", System.Type.GetType("System.String"));dt.Columns.Add("PhotoName", System.Type.GetType("System.Byte[]"));for (int i = 0; i < list.Count; i++){DataRow dr = dt.NewRow();dr["Caption"] = list[i].Name;dr["Department"] = list[i].Department;string imagePath = @"D:\C#\photos\" + list[i].PhotoPath;dr["PhotoName"] = getImageByte(imagePath);dt.Rows.Add(dr);}gridControl1.DataSource = dt;}//返回图片的字节流byte[]private byte[] getImageByte(string imagePath){FileStream files = new FileStream(imagePath, FileMode.Open);byte[] imgByte = new byte [files.Length ];files.Read(imgByte, 0, imgByte.Length);files.Close();return imgByte;}

26.检查数据的有效性

在gridview的ValidateRow事件中加入检查代码：

#region 检查数据private void gridView1_ValidateRow(object sender, ValidateRowEventArgs e){GridView view = sender as GridView;view.ClearColumnErrors();if (view.GetRowCellValue(e.RowHandle, "ReceiveDate") == DBNull.Value){e.Valid = false;view.SetColumnError(view.Columns["ReceiveDate"], "必须指定日期");}}

27.设某一列文字和标题局中显示

gridView1.Columns[0].AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;gridView1.Columns[0].AppearanceCell.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;

28.列表过滤条件多选

列名.OptionsFilter.FilterPopupMode= DevExpress.XtraGrid.Columns.FilterPopupMode.CheckedList

29.隔行换色的方法

this.gridView1.Appearance.OddRow.BackColor = Color.White;  // 设置奇数行颜色 // 默认也是白色 可以省略 
this.gridView1.OptionsView.EnableAppearanceOddRow = true;   // 使能 // 和和上面绑定 同时使用有效 
this.gridView1.Appearance.EvenRow.BackColor = Color.WhiteSmoke; // 设置偶数行颜色 
this.gridView1.OptionsView.EnableAppearanceEvenRow = true;   // 使能 // 和和上面绑定 同时使用有效
