Hierarchal Grid - Expended Row

[ELBU]

Hi all,
I'd very appreciate your help in the following question.

I have hierarchal grid with 2 levels.
after user expanding some row , I want in code behind to know what is the value of some column  
for example : 1 level - students , 2 level - their grades
id   name    age
----   ------    ------
111      Anna    25
         subject        grade
          ---------       --------
          math             100
          english           99

222      Inna      30

what I need is in code behind if user expanded "Anna" is to get "111" value.

P.S. If there is some grid event for catching the expansion on server , write it also for me please .

THANK A LOT

Hi,

You can try out the following code in the PreRender event of the grid to access the cell value of a row when it is expanded:
cs:

 protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
       foreach (GridDataItem dataItem in RadGrid1.MasterTableView.Items)
        {
           if (dataItem.Expanded)
            {
                {
                   string strtxt = dataItem["id"].Text;
                }
            }
        }
     }

Thanks
Princy.
