Issue:How to update Server Control(TextBox) from a thread running in code behind in vb.net.

Discussion in 'ASP .Net' started by Jitendra Singh via .NET 247, Mar 30, 2005.

  1. If I start a thread in code behind and that thread, after the page got loaded, want to update the value in TextBox(Server control or HTML control). It gives no error but value is not shown on the page. Pls Give the solution If 1 know....Thanks...

    Starting a new Thread causes two paths of execution. The first path which
    was the Request into your webserver completes the request and thus it's long
    gone by the time your second thread tries to update a TextBox on the page.
    You're starting to play with fire, so be careful until you've spent a lot
    of time testing and understanding what you're doing.

    There's a good article by Fritz that discusses how to create asychronous
    pages which might help get you going down the right track:
