webform页面传值

本文主要是介绍webform页面传值，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1、get方式

发送页

<form id="form1" runat="server"><div><a href="WebForm2.aspx?name=5">调转到Form2</a><asp:Button ID="button2" Text="跳转页面" runat="server" οnclick="button2_Click"/></div>
</form>protected void button2_Click(object sender, EventArgs e)
{Response.Redirect("WebForm2.aspx?name=5");
}

接受页

this.Label1.Text = Request["name"];
//this.Label2.Text = Request.Params["name"];
//this.Label3.Text = Request.QueryString[0];

2、post方式

a\不带 runat="server"形式

发送页

<form id="form2" action="WebForm2.aspx" method="post"><input name="txtname" type="text" value="lilili"  /><input type="submit" value="提交网页" />
</form>

接受页

this.Label1.Text =Request.Form["txtname"];

b\带 runat=“server”

发送页

<form runat="server" id="form3"><input id="btnTransfer" type="button" onclick="post();" runat="server" value="跳转" /> 
</form>
<form id="form4" method="post"><input type="text" runat="server" id="txtname" value="lili" />
</form>
<script type="text/javascript">function post() {form4.action = "WebForm2.aspx";form4.submit();}
</script>

接受页

this.Label1.Text =Request.Form["txtname"];

3、Session 和 Application

Session["name2"] = "sessontest";
Application["name3"] = "applicationtest";this.Label2.Text =(string)Session["name2"];
this.Label3.Text =(string)Application["name3"];

4、静态变量

发送页

public static string statest="static string";
protected void button2_Click(object sender, EventArgs e)
{Server.Transfer("WebForm2.aspx");
}

接受页

this.Label1.Text = WebForm1.statest;

5、Context.Handler 获取控件

发送页

<asp:TextBox ID="TextBox1" runat="server" Text="lilili"></asp:TextBox>
<asp:Button ID="button2" Text="跳转页面" runat="server" οnclick="button2_Click"/>protected void button2_Click(object sender, EventArgs e)
{Server.Transfer("WebForm2.aspx");
}

接受页

//获取post传过来的对象
if (Context.Handler is WebForm1)
{WebForm1 poster = (WebForm1)Context.Handler;this.Label1.Text = ((TextBox)poster.FindControl("TextBox1")).Text;
}

6、Context.Handler 获取公共变量

发送页

public string testpost = "testpost";
protected void button2_Click(object sender, EventArgs e)
{Server.Transfer("WebForm2.aspx");
}

接受页

//获取post传过来的对象
if (Context.Handler is WebForm1)
{WebForm1 poster = (WebForm1)Context.Handler;this.Label2.Text = poster.testpost;}

7、Context.Items 变量

发送页

protected void button2_Click(object sender, EventArgs e)
{Context.Items["name"] = "contextItems";Server.Transfer("WebForm2.aspx");
}

接受页

//获取post传过来的对象
if (Context.Handler is WebForm1)
{this.Label3.Text = Context.Items["name"].ToString();
}
