Expand child column by default

[Rahul Khinvasara]

Hi,
        I am using rad grid. In that I have designed 3 level hierarchy.
Thus when I click on '+' sign of first level it expands. When I click on '+' sign of second level it expands.

Now my requirement is that I want this second level to be expanded by default without clicking on the '+' sign. Thus when I click on first level it should be expanded and it that I can see the third level in expanded format  be default.

Thanks,
Rahul

Hi Rahul,

Try the following code snippet to achieve the desired scenario.

CS:

  protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
        foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
        {
            if (item.Expanded)
            {
                GridTableView childTableView=item.ChildItem.NestedTableViews[0];

                foreach (GridDataItem childitem in childTableView.Items)
                {
                    childitem.Expanded = true;
                }
            }
        }
    }

Hope this helps..
Shinu.
