ASP.NET MessageBox problem

[walterd]

Hi all

I have created a javaScript Alert function that brings up a messagebox based
on the message sent by the codebehind code. The message is displayed
correctly, but the problem is - the messagebox brings up a blank page,
display the message correctly, after clicking OK, the actual page is
displayed.
Can anyone tell me what is going on and how to fix this. I want the
messagebox to pop-up on the same page from where it is invoked. Please
help!!!

Thanks

Instead of using Response.Write("<script>alert('Blank Page')</script>");
you want to use instead
Page.Controls.Add(new LiteralControl("<script>alert('Blank
Page')</script>");
The former is a blocking call which occurs in the middle of page processing.
The latter occurs after the page is processed.

Another approach would be to use :

Page.RegisterStartupScript(keyname, "<script
language=""JavaScript"">alert(...);</script>")

Where keyname is a name for the script block.
