I am currently struggling with the implementation of the jQuery Dialog in an Visual Basic Web Application. In the following code there is a Button, that forces a jQuery dialog to open. I just want to access the result of the dialog (Yes/No) in the Visual Basic Code.

This is my VB-Code:

<input id="hfSandbox" type="hidden" runat="server" /> <asp:Button runat="server" ID="btnSandbox" OnClick="btnSandbox_Click" Text="Button" /> <div id="dialog" >Everything OK?</div>

With following Javascipt code i want to set the value of a hidden field to true or false, depending on which response the user chooses. With an alert I check, if the value is set correctly (if user chooses "Yes").

 $(function () { $("#dialog").dialog({ title: "Bestätigung", buttons: { Yes: function () { document.getElementById("<%=hfSandbox.ClientID%>").Value = "True" alert(document.getElementById("<%=hfSandbox.ClientID%>").Value) $("[id*=btnSandbox]").click(); }, No: function () { $(this).dialog('close'); } } }); });

After that, I trigger the click event in VB. In the VB function I want to access the value of the hidden field.

Protected Sub btnSandbox_Click(sender As Object, e As EventArgs) MsgBox(hfSandbox.Value) End Sub

This is where I fail. The message box has no content. I tried several things I read in other communities- but no luck. I hope you can help me!

Cheers
