Hi
I got a Button, a textbox a Panel in my page, when the page is loaded, the Panel will filled with pictures and link, then then the button is click, it will popup the panel as ModalPopup, when user clicked on the link accompanied with the picture, the code assigned will send to the textbox.
My problem is as the page is shows, I can see the picture populated inside the panel(which suppose to be invisible after using ModalPopupExtender), then it hidden again, but things works. Then I wanted to populate the code to my textbox using UpdatePanel, but it just cause the page to post back, here attached with my codes, hope will got a solution or a pointer from you guys, thanks.

It is not recommended to add the line number to your source code.Would you modify it and share your Aspx source code here?

Hi stephensaw,
I've got everything ready. But I'm not sure about what you really what to do now? Do you what to post a asynchronous Request to the server?
If yes, here is the sample:
<%@. Page Language="VB" AutoEventWireup="true" CodeFile="Default.aspx.vb" Inherits="_Default" %><%@. Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <title>Untitled Page</title> <link href="StyleSheet.css" rel="stylesheet" type="text/css" /> <script type="text/javascript"> if (window.screen) { this.moveTo(0, 0); this.resizeTo(screen.availWidth,screen.availHeight) } </script></head><body> <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" runat="server" /> <asp:UpdatePanel ID="updateCollar" runat="server"> <ContentTemplate> Please select a collar design form our gallery: <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label> <asp:TextBox ID="txtCode" runat="server" ReadOnly="True"></asp:TextBox> <asp:Button ID="btnBrowse" runat="server" Text="Browse" OnClick="btnBrowse_Click" /> <div style="display: none"> <asp:Button ID="btnPopTrigger" runat="server" Text="Button" /> </div> <cc1:ModalPopupExtender ID="PopupCollar" runat="server" BackgroundCssClass="ModalPopupBackground" PopupControlID="pnlPopup" TargetControlID="btnPopTrigger"> </cc1:ModalPopupExtender> <asp:Panel ID="pnlPopup" runat="server" Height="500px" Width="630px" BackColor="White"> </asp:Panel> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="btnBrowse" /> </Triggers> </asp:UpdatePanel> <br /> </form> <script type="text/javascript" language="javascript"> var btnID = ""; Sys.WebForms.PageRequestManager.getInstance().add_beginRequest( function(sender,args){ btnID = args._postBackElement.id; } ); Sys.WebForms.PageRequestManager.getInstance().add_endRequest( function(sender, args){ if(btnID =="<%=btnBrowse.ClientID%>"){ $get("<%= btnPopTrigger.ClientID%>").click(); } } ); </script></body></html>C# code modified.
Protected Sub btnBrowse_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Label1.Text = "updatepanel updated"
End Sub
Hope it helps.If I misunderstood you, please let me know.
Thanks Jonathan for your effort to help me. Actually my update panel and all the stuff works well. Here I will explain more.
I got a button, a panel, a text box. When the page is load, I will runtime looping create image button which I retrieve detail from database, I will runtime create another panel and table, which then everything will be populated to my present panel. This will will popup when clicked the button. The problem was, at my page load, I can see the panel during the population of my controls. The problem 'shows' too fast, couldn't have it capture to picture, below is the video I captured.

Hi stephensaw,
Based on your description, I thinkmake your pnlPopup hide as default.
<asp:Panel ID="pnlPopup" runat="server" Height="500px" Width="630px" BackColor="White"style="display:none"> </asp:Panel>
Hope it helps.
Hi stepensaw,
I have done some modifications based on your source code. And now we can select images without any postback and the implements moved to client side. Hope it will benefit our numbers.
