Expand Programmatically

[Developer Developer]

Is there an easy way to programmatically expand a row in a hierarchy?  For example, when the page loads I would like to expand the first three rows, but leave the remaining rows collapsed.  Any help would be greatly appreciated.

Thanks!

Hello,

You can try implementing the following code snippet to expand specific rows on page load in a hierarchy.

CS:

 protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
        foreach (GridDataItem dataitem in RadGrid1.MasterTableView.Items)
        {
            if ((dataitem.ItemIndex == 0) || (dataitem.ItemIndex == 1) || (dataitem.ItemIndex == 2))
            {
                dataitem.Expanded = true;
            }
        }
    }

Thanks
Princy.
