 DataRow[] changedRows
protected void RadGrid1_UpdateCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e) 
  
    GridEditableItem editedItem = e.Item as GridEditableItem; 
    UserControl userControl = (UserControl)e.Item.FindControl(GridEditFormItem.EditFormUserControlID); 
   
    //Prepare new row to add it in the DataSource 
===>      DataRow[] changedRows = this.SqlDataSourceRate.Select( 
    "SnapShotID = " + editedItem.OwnerTableView.DataKeyValues[editedItem.ItemIndex]["SnapShotID"], 
    "Type = " + editedItem.OwnerTableView.DataKeyValues[editedItem.ItemIndex]["Type"], 
    "Engine = " + editedItem.OwnerTableView.DataKeyValues[editedItem.ItemIndex]["Engine"], 
    "Usage = " + editedItem.OwnerTableView.DataKeyValues[editedItem.ItemIndex]["Usage"]); 
   
    //if (changedRows.Length != 1) 
    //{ 
    //    RadGrid1.Controls.Add(new LiteralControl("Unable to locate the Employee for updating.")); 
    //    e.Canceled = true; 
    //    return; 
    //} 
   
   
    //Update new values 
    Hashtable newValues = new Hashtable(); 
    newValues["UsageRate_Light_Rate"] = (userControl.FindControl("txtLightRate") as TextBox).Text; 
    newValues["Type"] = (userControl.FindControl("txtTypeNumber") as TextBox).Text; 
    newValues["Engine"] = (userControl.FindControl("txtTypeNumber") as TextBox).Text.Substring(0, 1); 
   
    newValues["MaxTerm_Heavy_Rate"] = (userControl.FindControl("txtMaxHeavyRate") as TextBox).Text; 
    newValues["MaxTerm_Medium_Rate"] = (userControl.FindControl("txtMaxMediumRate") as TextBox).Text; 
    newValues["MaxTerm_Light_Rate"] = (userControl.FindControl("txtMaxLightRate") as TextBox).Text;

    changedRows[0].BeginEdit(); 
    try 
    
    foreach (DictionaryEntry entry in newValues) 
    
      changedRows[0][(string)entry.Key] = entry.Value; 
    
    changedRows[0].EndEdit(); 
    
    catch (Exception ex) 
    
    changedRows[0].CancelEdit(); 
    //Label1.Text += "Unable to update Employees. Reason: " + ex.Message;

You really do have 4 arguments there. Look at the documentation and educate yourself. There are only 3 overloads to the method. None take more than 3 parameters.
