radgrid +own server control +update panel

[Łukasz Kuryło]

Hi all.
I have a own server control which derive from RadGrid
public class MyGrid : Telerik.Web.UI.RadGrid{}

I want to render that control in the update panel (I don't want the postback to the server when e.g. I want to sort data in column).
How can i do that?

My code at this moment.

        protected override void CreateChildControls()
        {
            base.CreateChildControls();
            Control parent;
            Control container;

            ScriptManager sm = ScriptManager.GetCurrent(Page);

            if (sm == null || !sm.EnablePartialRendering)
            {
                container = new Control();
                parent = container;
            }
            else
            {
                UpdatePanel up = new UpdatePanel();
                container = up.ContentTemplateContainer;
                parent = up;
            }

            this.Controls.Add(parent);
        }

        protected override void RenderContents(HtmlTextWriter output)
        {
            EnsureChildControls();

           //parent.RenderControl(output);
            base.RenderContents(output);
        }

[edit]
I'va found a RadAjaxManager control. Maybe this will be better for this solution than update panel, but still I don't know how to render my derived class with this control. I need this all in one dll file.

All right.
After a few hours I did it.

        protected override void OnPreRender(EventArgs e)
        {
            RadAjaxManager m = RadAjaxManager.GetCurrent(this.Page);
            m.AjaxSettings.AddAjaxSetting(this, this);
            base.OnPreRender(e);
        }

It's simpler than I expected.
