[CLOSED] Load control to 1 tab at time

[Daniil]

Also the following can help.

protected override void OnLoad(EventArgs e)
{
    base.OnLoad(e);
    btnCreate.SuspendScripting();
    btnCreate.Hidden = true;
    btnCreate.ResumeScripting();
}
        
protected override void OnPreRender(EventArgs e)
{
    base.OnLoad(e);
    btnCreate.SuspendScripting();
    btnCreate.Hidden = false;
    btnCreate.ResumeScripting();
}

If a control is designed to be used with Ext.NET and that control is going to be recreated during an Ext.NET AJAX request (DirectEvent or DirectMethod), you should suspend scripting for all property changes during the whole control life cycle starting from "base.onInit(e)" (see the example below). It is aslo actual for a control's child controls (as demonstrated in the example above).

Example

protected override void OnPreRender(EventArgs e)
{
    base.OnPreRender(e);
    this.SuspendScripting();
    this.Hidden = true;
    this.ResumeScripting();
}

"starting from "base.onInit(e)" means that you can initialize the control's (and its chilldren's) properties within a control's constructors or prior to "base.OnInit(e)" call without suspending of scripting.

I've add SuspendScripting() and ResumeScripting() in parent control(which contains button with ID="btnCreate" which generate error) and this not work. I've added at all OnInit,OnLoad,OnPrerender Events of control.

Ok but don't recreating control if event TabChange occurs work for me;)
Thanks a lot @Daniil:)

thread can be closed:)

Strange, it works for me. If you want to sort it out, please provide a full test case again. If no, we can just close the thread.
