private void WebGrid1_CustomAggregate(object sender,
ISNet.WebUI.WebGrid.CustomAggregateArgs e)
{
    if (e.Column.DataMember == "Status") 
    {
        WebGridRowCollection rows = e.Rows;
        int count = 0;
        for (int i=0; i < rows.Count; i++) 
        {
            WebGridCell cell = rows[i].Cells[e.Column.Position];
            if (cell.Value.ToString() == "Active")
            {
                count++;
            }
        }
        e.AggregateResult = count;
    }
}

Remarks

The aggregation functions such as Count, Sum, Average, Min and Max are generally applicable to most application's requirements. However, they do not allow you to perform your own calculation on the grouped rows or footer's totaling.
