Hi all,
I must admit I'm a beginner in ASP.NET so this might be a newbie problem:
I am creating a web part with search functionality. The content of a remote search shall then be displayed later. In the meanwhile, an animation shall indicate that the search is still pending.
In my web part, I am using UpdatePanel (for the partial page load), UpdateProgress (to display an animation in the meanwhile), and a Timer(to be able to trigger polling by the client for new data available).
If I now want to paste my web on a page, I get the error message: "The control with ID 'SearchUpdateProgress' requires a ScriptManager on the page". If I remove the UpdateProgress component, I get a similar message for the Timer.
I already have a ScriptManager on the Master page and my Update Panel seems to recognize that (removing UpdateProgress and Timer and just leaving the UpdatePanel works).
Does anybody have an idea what I've done wrong?
Best regards and thanks!
Sebastian
