  Hello Tina,
  
  Try the following code snippet in SelectedIndexChanged event of RadComboBox.
  C#:
  

  protected void combo_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)

  {

    RadComboBox combo = (RadComboBox)sender;

    GridDataItem item = (GridDataItem)combo.NamingContainer;

    string id = Convert.ToInt32(item.GetDataKeyValue("ID")).ToString();

  }

  
  Thanks,
  Shinu.

  Hello Tina,
  
  In order to get the datakeyvalue, attach the event OnClientSelectedIndexChanged from server side and pass the index.
  C#:
  

  protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)

  {

      if (e.Item is GridDataItem)

       {

          GridDataItem dataItem = (GridDataItem)e.Item;

          RadComboBox combo = (RadComboBox)dataItem.FindControl("Radcombo");

         int index = e.Item.ItemIndex;

         combo.OnClientSelectedIndexChanged = "function (sender,args){rowIndex('" + index + "');}";             

       }

  }

  
  Javascript:
  

  function rowIndex(index)

  {

     var row = $find('<%= RadGrid1.ClientID %>').get_masterTableView().get_dataItems()[index];

     alert(row.getDataKeyValue("ID"));//DataKeyName

  }

  
  Thanks,
  Shinu.
