I have a RadWindowManager and a RadGrid inside a RadUpdatePanel and for some reason my RadAlertMessage won't show.  It works great when I remove the panel.

Here is my Alert function:
Public Sub ShowRadAlertMessage(ByVal message As String)
    
Dim radalertscript As String = "<script language='javascript'> Sys.Application.add_load(function(){radalert('" & message & "', 330, 210);})</script>"
    Page.ClientScript.RegisterStartupScript(Me.[GetType](), "radalert", radalertscript)
End Sub

All I do is call it and pass it the message that I want displayed.  What can I do to get this to work inside the update panel?

Hello Ronnie,

You do not need Sys.Application.add_load. Here is an example how to achieve your goal:

ScriptManager.RegisterStartupScript(Page, GetType(Page), "radalert", "radalert('Hi!');", True)

All the best,

Thanks Vlad for the response.  I changed my alert function to this and it still isn't working correctly.  Am I missing something else?

Public Sub ShowRadAlertMessage(ByVal message As String)
    Dim radalertscript As String = "radalert('" & message & "')"
    Page.ClientScript.RegisterStartupScript(Page.GetType(), "MyAlert", radalertscript, True)
End Sub

Hello Ronnie,

Would you please try the approach suggested by Vlad?
Public Sub ShowRadAlertMessage(ByVal message As String
    Dim radalertscript As String = "radalert('" & message & "')" 
    ScriptManager.RegisterStartupScript(Page, Page.GetType(), "MyAlert", radalertscript, True
End Sub  

Let us know whether this helps.

I am getting javascript error when I use that function.  It says,

'this._windwos.length' is null or not an object

and

Object doesn't support this property or method.

Hello Ronnie,

Do you have RadWindowManager on this page?

Hello Ronnie,

I have yet another suggestion.

Please take the RadWindowManager out of the RadAjaxPanel control and try again.

Let us know if you need more information.

Thanks Both of you, that was exactly the issue.  I had the Rad window inside the update panel along with my grid.  I appreciate all the help.
