Hi

How to call the event ItemDataBound

this is my event

protected void grdReport3_ItemDataBound(object source, System.Web.UI.WebControls.DataGridItemEventArgs e)
{

if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{

DataRowView rv = (DataRowView)e.Item.DataItem;


DateTime iap = Convert.ToDateTime(rv.Row.ItemArray[3]);
DateTime iaa = Convert.ToDateTime(rv.Row.ItemArray[4]);


if (iaa > iap)
{
e.Item.BackColor = System.Drawing.Color.Red;
}

}
