I've search thru all the thread regarding RadAlert not working and I still can't figure out why I get nothing at all, no errors in code, no exceptions triggered, nothing.

Here is my code:

<telerik:RadScriptManager ID="rsmLogin" runat="server" EnableHandlerDetection="false" EnableScriptCombine="false"></telerik:RadScriptManager>

<telerik:RadSkinManager ID="rskmLogin" runat="server" Skin="Default"></telerik:RadSkinManager>

<telerik:RadInputManager ID="rimLogin" runat="server"></telerik:RadInputManager>

<telerik:RadWindowManager ID="rwmLogin" runat="server" EnableShadow="true"></telerik:RadWindowManager>

<script type="text/javascript">

function callBackFn(arg)

{

alert("this is the client-side callback function. The RadAlert returned: " + arg);

}

</script>

<telerik:RadPageLayout ID="rpl_Login" runat="server" GridType="Fluid" Width="248px" Style="margin:2px; align-content:center;">

<Rows>

<telerik:LayoutRow style="height:42px; margin-top:8px">

<Columns>

<telerik:LayoutColumn style="text-align:center; align-content:center">

<telerik:RadButton ID="rbn_SignIn" runat="server" Text="SIGN IN" Font-Size="Large" Width="100"></telerik:RadButton>

</telerik:LayoutColumn>

</Columns>

</telerik:LayoutRow>

</Rows>

</telerik:RadPageLayout>

and code behind

Private Sub rbn_SignIn_Click(sender As Object, e As EventArgs) Handles rbn_SignIn.Click

Try

Me.rwmLogin.RadAlert("We're sorry, but we could not locate your account based on the credentials provided.", 500, 200, "Login Error", "callBackFn")

Catch ex As Exception

Dim ErrorLog As New DC.Errors.Log(ex)

End Try

End Sub

I also tried without the callBackFn which was pulled direction from your documentation sample.

Any suggestions?

Cheers, Rob.

Hi Rob,

The problem with this snippet is in the apostrophe in the server code that terminates the JavaScript string too early and causes exceptions on the client side that you can monitor in the browser console. The solution is to escape it: https://docs.telerik.com/devtools/aspnet-ajax/controls/window/troubleshooting/calling-the-predefined-dialogs-from-the-server-methods.
