  Is it possible to put updatepanel in a control that will be used in GridView ItemTemplate?

  Mar 20, 2006 05:04 AM|LINK

  I can make GridView wrapped in UpdatePanel. But when I put it into a control, and put the control in a GridView's itemtemplate, I get

  The UpdatePanel 'UpdatePanel2' was not present when the page's InitComplete event was raised. This is usually caused when an UpdatePanel is placed inside a template.

  [InvalidOperationException: The UpdatePanel 'UpdatePanel2' was not present when the page's InitComplete event was raised. This is usually caused when an UpdatePanel is placed inside a template.]

  I am not sure if it is because I didn't set it right, or ATLAS can not handle it?

  thanks

  hello. well, you can bind in a previous event of the page. for isntance. i've built a small page that shows the kind of problem you're gonna face with this approach: <script runat="server"> public struct A { private string nome; public string Nome { get { return nome; } set { nome = value; } } private string morada; public string Morada { get { return morada; } set { morada = value; } } public A(string n, string m) { nome = n; morada = m; } } public void Bind() { A[] a= new A[]{ new A( "1", "1" ), new A( "2", "2" ), new A( "3", "3" ) }; grid.DataSource = a; grid.DataBind(); } protected override void OnLoad(EventArgs e) { base.OnLoad(e); } protected override void OnInit(EventArgs e) { base.OnInit(e); Bind(); } void T(object sender, EventArgs Args) { info.Text = ((TextBox)sender).Text; } string Handle(A a) { return a.Nome; } </script> <form id="form1" runat="server"> </form> when you run the page you'll see that the label allways presents the text of the last row...
