ASP.NET UpdatePanel Time Out

Question

I\'m making a request from an UpdatePanel that takes more then 90 seconds. I\'m getting this timeout error:

Microsoft JScript runtime err

Answer 1

In my case the ScriptManager object was created in a Master Page file that was then shared with the Content Page files. So to change the ScriptManager.AsyncPostBackTimeout property in the Content Page, I had to access the object in the Content Page's aspx.cs file:

protected void Page_Load(object sender, EventArgs e)
{
     . . . 
     ScriptManager _scriptMan = ScriptManager.GetCurrent(this);
     _scriptMan.AsyncPostBackTimeout = 36000;
}
