When I put this code in my load function it works just fine.
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArg s) Handles MyBase.Load
RegisterStartup Script("", "<script language='JavaS cript'> CreateWnd
('PleaseWait.as px', 500, 50, false); </script>")
End Sub
But when I put it in another server control it doesn't work:
Private Sub ImageList_ItemC ommand(ByVal source As Object, ByVal e As
System.Web.UI.W ebControls.Data ListCommandEven tArgs) Handles
ImageList.ItemC ommand
RegisterStartup Script("", "<script language='JavaS cript'> CreateWnd
('PleaseWait.as px', 500, 50, false); </script>")
End Sub
Can someone tell me why this isn't working?
And here is the script code.

Joseph,
Why is the first parameter to RegisterStartup Script an empty string?
What do you mean by "this isn't working"? Do you get an error
message?

I put an empty string because I figured I didn't need to use a key value.
And I don't get an error message, its hits that part of the code and doesn't
do anything.
When I step through the code when its in the load function, I get my popup.
But when I do it anywhere else I don't get my popup.

Hi:
I believe you must complete the first parameter because it's an

Joseph,
When the user clicks on an item, are you expecting the above code to
cause the window to popup? If so, please realize that server-side
code cannot directly cause client-side JavaScript to execute. You
will have to inject calls to the JavaScript in the ASP.Net controls
when the page is built (this is usually done in Page_Load).
Unfortunately, there seems to be a lack of resources on the web as to
how to integrate client-side JavaScript code and server-side
ASP.Net code. It's quite elegant when you know how, but getting that
knowledge can be a real challenge.
Right now I'm pretty much guessing as to what you want your code to
do. So, if you'd like, please post a step-by-step description of
what you want to happen, something like:
- page with datagrid is displayed on the client
- user clicks an item in the datagrid
- client-side code shows a window in response to the click
- postback occurs
We can use an algorithm like this as a starting point to getting the
JavaScript calls wired into the correct places at the correct point
in the page's lifecycle.

Hope this helps.
Chris.
