Group Header Totals

[Allan]

I know we can perform calculations and add them to a group header:

Private Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs)

    If TypeOf e.Item Is GridGroupHeaderItem Then
        Dim item As GridGroupHeaderItem = CType(e.Item, GridGroupHeaderItem)
        Dim groupDataRow As DataRowView = CType(e.Item.DataItem, DataRowView)
        item.DataCell.Text = (item.DataCell.Text + "; Avg: ")
        item.DataCell.Text = (item.DataCell.Text + (CType(groupDataRow("total"), Decimal) / Integer.Parse(groupDataRow("count").ToString)).ToString)
    End If
End Sub

But is there a way to just add the Column aggregate:

<telerik:GridBoundColumn DataField="Subject" FilterControlAltText="Filter Subject column"
HeaderText="Subject" SortExpression="Subject" UniqueName="Subject" ItemStyle-HorizontalAlign="Left"
FooterStyle-HorizontalAlign="Left" FooterText="Tickets " Aggregate="Count">
</telerik:GridBoundColumn>

Thank you in advance.

Hi Allan,

Please check out the following live example which demonstrates how to use the aggregate into the footer on the groups.
