Edit and updating columns in radgrid

We recently bought Asp.net Ajax control. We are migrating to asp.net grid ti radgrid. In my grid I ma editing and updating my rows. When I am trying to implement that in radgrid I am getting too many errors. Can any one help me how to do that? In which command i need to write the code???

What i want is once i edit the radgrid, i just want to catch the text in the textbox after i edited it. See the modified question above.

the above functionality i did in gridview as follows. But i dont know how to do it radgrid.

protected void gvCktMap_RowUpdating(object sender, GridViewUpdateEventArgs e) 
{ 
    try 
    { 
        if (Session["TaskID"] != null) 
        { 
            string strTaskID = (string)Session["TaskID"]; 
            if (strTaskID != string.Empty) 
            {                     
                bool bolStatus = false; 
                clsTaskUpdates_BL objBL = new clsTaskUpdates_BL(); 
                Label lblOrdID = (Label)gvCktMap.Rows[e.RowIndex].FindControl("lblorderId"); 
                string strOrdId = lblOrdID.Text; 
                DataSet dsStatus = objBL.getTaskStatus_BL(lblOrdID.Text.Trim(), strTaskID.Trim()); 
                if (dsStatus.Tables[0].Rows.Count > 0) 
                { 
                    if (dsStatus.Tables[0].Rows[0][0].ToString() == "3" || dsStatus.Tables[0].Rows[0][0].ToString() == "4") 
                        bolStatus = true; 
                }

Start with the demos available on Telerik's site, and work from there.

Or, rebuild your grid from scratch using the radgrid.
