Hey folks.

For you guys struggling with one of the following errors (or both if you try to render a new ScriptManager)
 
 - Only one instance of a ScriptManager can be added to the page.
 - The control with ID 'xx' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.

The solution is to make sure that the ScriptManager is rendered BEFORE the given RAD Control, and that only one ScriptManager exists. The following code snippet should achive this:

protected override void CreateChildControls()
{
     if (ScriptManager.GetCurrent(this.Page) != null)
     {

          this.sm = ScriptManager.GetCurrent(this.Page);
     }
     else
     {
          this.sm = new ScriptManager();
          this.Controls.Add(this.sm);
     }
}

Now make sure the ScriptManager is rendered BEFORE the controls needing it (ie RadEditor)

protected override void Render(System.Web.UI.HtmlTextWriter writer)
{
     this.sm.RenderControl(writer);
     this.radEditor.RenderControl(writer);
}

Hopefully this will be helpful to someone else.

asp:Button ID="btnClose" CssClass="cmb_btnG" Text="<%$ CmbResources:eBAM,LEList_btnClose %>"

var tooltip = Telerik.Web.UI.RadToolTip.getCurrent();

if (tooltip)

{

tooltip.hide();

}

}

Hi Telerik team,

I need to create several RadGrid’s at run time according to the result of some queries, this means that I don’t have the exactly amount of RadGrids to be created on each pageload.

So at this point I am able to create the RadGrdis as needed, but I can’t make paging functionality works as expected.

I can surf only the first and second page, of my RadGrids, after that it appears that My RadGrids are not persisting on the server. I have try many options as enable the ViewState property, and others but without successful.

I am trying to follow this article to achieve my goal but I can not make, pages work as expected.

 Based on this article http://www.telerik.com/help/aspnet/grid/grdprogrammaticcreation.html Section: Create Telerik RadGrid entirely in the code behind

Any comment will be very useful.
Thanks in advanced.
