__doPostBack is not working in .net 4.0

Question

I have website in asp.net 4.0, where i used,

litAlert.Text = "<script language=javascript>alert('Some Error(s) occured while processing your request. Click Ok to view the Error Details.');__doPostBack('btnTemp','')</script>";                                            

But when i am trying to debug, it will not call btnTemp onclick event.

Please give me solution regarding this issue.

Answer 1

You could at this to Page_PreRender

protected void Page_PreRender(object sender, EventArgs e)
{
    this.Page.ClientScript.GetPostBackEventReference(litAlert, string.Empty);
}
