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.

Thanks Shinu.
But i want to access hte row in which combobox is present and then access the datakeyvalue.how can it be done?

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.
