Hi,
A little trick in order to get Previous Page Control Values after a Cross-Page Posting.
Take a first Sample Page named Default.aspx containing a TextBox and a Button.
We set the PostBackUrl of the Button to our Second Page : Page2.aspx
<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:Button ID="Button1" runat="server" Text="Button" PostBackUrl="~/Page2.aspx" />
</div>
</form>Now on the Page2.aspx OnLoad Event we do the following code. The Trick resides in the PreviousPage property of the Page property.
So we can do a FindControl<> with the name of the TextBox from the Default.aspx page.
protected void Page_Load(object sender, EventArgs e)
{
String s = String.Empty;
if (PreviousPage != null && PreviousPage.IsCrossPagePostBack)
{
TextBox txt = PreviousPage.FindControl<TextBox>("TextBox1");
Response.Write("CrossPosting : " + txt.Text);
}
}Here is the Result :
Hope this help's!
Stay Tuned :)
