“ Cross-page postback, simplified. To amend our discussion on how to retrieve data from a form that postback'd to a different page - I found the example I was talking about last night. You can reference the control value without any references or casting of the page object: In calling Page2.aspx: <asp:TextBox ID="postBackTextBox" runat="server" Style="z-index: 101; left: 58px; position: absolute; top: 71px"></asp:TextBox> <asp:Button ID="okButton" runat="server" PostBackUrl="Page3.aspx" Style="z-index: 103; left: 245px; position: absolute; top: 69px" Text="Button" /> notice ID="postBackTextBox" and PostBackUrl="Page3.aspx". when the button is clicked, the postback goes to Page3 rather than normal Page2. in Page3.aspx code (e.g. Page_Load event), you retrieve the posted-back value like this: string val = Request["postBackTexBox"].ToString(); Try it, it's that simple. ”
