ASP.NET AJAX: $get and $find return null
I'm using the .NET 3.5 framework and Visual Studio 2008, developing a custom extender that points to another extender using an ID. I cannot get a reference to that extender through the ID on the client side using $get and $find.
The extender exists, the ID is valid (using ClientID property), so it should be able to reference it, but I've tried to get access to the control on the client side init and load events and in the initialize method, as well as rendering a script using ScriptManager.RegisterClientScriptBlock and RegisterStartupScript.
Any ideas why I can't reference using $get and $find? I see the controls in the markup, and the script is running at the end....
