Question

I’m having surprisingly bad luck finding a decent resource for this. But What I’m doing is creating a list of tickets using a ListView. One of the controls in the item template is a link button that shows the header of the ticket. When the user clicks the link button, I want to open a modal window that shows the ticket in readable format. To get the ticket, I’ll be passing that page a variable and it’ll do the rest; nothing complicated. The page will have 3 buttons and the windows needs to close when you click one of them.

Now, I figured out how to use the ModalPopupExtender from the Ajax tookit more or less. You create the panel in it’s own div which stays hidden. I created a click event that basically uses a webclient to download the html from the page and insert it into that div’s innerHtml. This seems to work the first time. But as soon as you click a different link, the page pukes and says something about it being in an illegal state.

I’m not sure if I’m going about this wrong, and I can’t find any decent examples of how to do this. Well there’s one, but the english is hard to understand and it’s in VB instead of C#. Any help?

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>
  <form id="form1" runat="server"> 
    <div> 
        <asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server"> 
        </asp:ToolkitScriptManager> 

        <br /> 

<asp:ModalPopupExtender 
DropShadow="true" 
OkControlID="btnOk" 
CancelControlID="btnClose" 
runat="server" 
PopupControlID="Panel1" 
id="ModalPopupExtender1" 
TargetControlID="Button1" /> 


<asp:Panel ID="Panel1" runat="server" CssClass="modalPopup" style="display:none;"> 
This is basic modal popup. 
<br /><br /> 
<asp:Button ID="btnOk" runat="server" Text="Ok" /> 
<asp:Button ID="btnClose" runat="server" Text="Close Me" /> 
  <iframe src="http://www.google.com"></iframe> 

</asp:Panel> 




<asp:Button ID="Button1" runat="server" Text="First Modal Popup" /> 


    </div> 
    </form>

    Try this it should work.
