[Resolved] ASPNET_MsgBox hides grid view

snufse · October 7th, 2008, 02:34 PM

I have an application that displays a header section and a grid view based upon selection in header. This work s fine. The user has a button where they can export the content of the grid view (using the data set) to a table. This works fine as well. When export is completed I need to show the user that the 'export function" has completed. I am using following code:

Code:

Public Overloads Sub ASPNET_MsgBox(ByVal Message As String)
hiddenMsgDiv.InnerHtml = "<script type=""text/javascript"">alert('" & Message.Replace("\", "\\").Replace("'", "\'") & "');</script>"
End Sub

Code:

<div id="hiddenMsgDiv" runat="server" style="display: none">

where I pass the message text. The message box is being displayed Ok but it hides the underlaying grid. When user clicks OK the grid appears again. Any ideas?

Got it working using this:

Code:

Page.ClientScript.RegisterStartupScript(Page.GetType(), Guid.NewGuid().ToString(), "alert(""" & Message & """)", True)

Not sure if this is correct or good solution

I suspect the problem is that you are doing a full repaint, and the javascript for the alert is inline with the processing of the HTML. When the browser is parsing it hits the javascript alert which is a blocking call stopping the rendering of the HTML.

Add this to your javascript tag:

defer="defer"

This will cause the javascript to run after the page as finished loading.
