  I have Sql Database and I want to bind it through LINQ from code-behind programmatically in C#.NET. How can I do that?
  
  I have the following code written:
  
  public void populatetree()
      {
  
          using (DataClasses1DataContext db = new DataClasses1DataContext())
          {
              MsgType mt=new MsgType();
              RadTreeView1.DataFieldParentID = mt.ParentID.ToString();
              RadTreeView1.DataFieldID = mt.ID.ToString();
              RadTreeView1.DataValueField = mt.ID.ToString();
              RadTreeView1.DataTextField = mt.Name;
              RadTreeView1.ToolTip = mt.Description;
             RadTreeView1.DataSource= ?
     
              RadTreeView1.DataBind();
              
          }
      }
  what shud I do for the datasource?

  Take a look at the Treeview Datasource for Linq to Entities versus a SQL Command in Code-Behind versus Code-In-Front blog post. The third example, although in VB.NET may be some help here as it populates a RadTreeView. Also, reference the Using Three Flavors of LINQ To Populate a TreeView post, as it provides insights into using LINQ with an ASP.NET Treeview.
  
  I'm working on a simple demo and will post it when done.
