PreviousPageType

Here is a type-safe approach in case of Server.Transfer as well. [Similar to the specified '<%@ PreviousPageType VirtualPath="Default.aspx" %> ' approach].

 

i.e For the below case, there is again a type-safe approach.

 

On Page2.aspx:

if (Request.Form ["TextBox1"] != "" )

Label1.Text = Request.Form["TextBox1"];

 

Modify the 'Default.aspx' page as:

 

1.    '<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" ClassName="_Default" %>'

 

Modify the 'Redirect.aspx' page as:

 

2.    <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Redirect.aspx.cs" Inherits="Redirect" %>

3.    <%@ Reference Page="~/Default.aspx" %>

 

Modify the 'Redirect.aspx'.cs' as:

 

4.    _Default prevPage = Context.Handler as _Default;

5.     Label1.Text= prevPage.PrevText;

 

Hope it helps.

 

Traditional way to achieve the cross page posting:

Lest assume that you are moving to Page2.aspx from Page1.aspx using Response.redirect and you want to access few or all the controls on Page1.aspx.

In general scenario you will use the Sessions to do this. But there is a better option:

Following is the code for button on Page1.aspx:

<asp:button id="Button1" text="Go to Page2 " postbackurl=" Page2.aspx" runat="Server"> </asp:button>

And on Page2.aspx:

text = ((TextBox)PreviousPage.FindControl("TextBox1")).Text;

 

That's it. In this way you can use any control on the previous page.

 

Yet another way to achieve this:

On Page1.aspx on button click:

protected void Button1_Click(object sender, EventArgs e)

{

        Server.Transfer("Page2.aspx",true);

}

 

On Page2.aspx:

if (Request.Form ["TextBox1"] != "" )

Label1.Text = Request.Form["TextBox1"];
