Hi Dingen,

As you are using sorting in the inner grid you should set the text to the sort LinkButton. Similar to the following:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
   {
       if (e.Item is GridHeaderItem)
       {
           (((GridHeaderItem)e.Item)["OrderID"].Controls[0] as IButtonControl).Text = "some text";
       }
   }
 

Kind regards,
