And code behind for radgrid

{

string instanceId = parentItem["INSTANCEID"].Text.ToString();
// txtToFtp.Text = Convert.ToString(instanceId);
lblInstance.Text = Convert.ToString(instanceId);
RadGrid rg = parentItem.ChildItem.FindControl("gvInstanceDetails") as RadGrid;
rg.Rebind();
RadGrid gvRaw = parentItem.ChildItem.FindControl("gvRawDetails") as RadGrid;
gvRaw.Rebind();

}
foreach (GridItem item in e.Item.OwnerTableView.Items)
{
if (item.Expanded && item != e.Item)
{
item.Expanded = false;
}
}
}
}
protected void Page_PreRender(object sender, EventArgs e)
{
// gvJobDeatail.Rebind();
}
