I'm trying to add totals to the headers of my grouping columns but can't figure out how to do it. As you can see from the image I attached I need to see the total ticket count for each region before or after it has been expanded and I need to same logic applied to the second grouping by client as well. Is this something that can be done or do I need to use detail grids here?

AllowAutomaticUpdates="false" AllowAutomaticDeletes="true" AutoGenerateColumns="false"

AllowSorting="true" AllowPaging="false" ShowFooter="true" PageSize="50" PagerStyle-Position="TopAndBottom">

<MasterTableView ShowGroupFooter="true" GroupsDefaultExpanded="false" HeaderStyle-BackColor="#7FA5D7"

ItemStyle-BackColor="#B0C4DE" AlternatingItemStyle-BackColor="White" FooterStyle-Font-Bold="true">

<telerik:GridBoundColumn HeaderText="Region" DataField="Region">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Client" DataField="ClientName">

I've figured out how to get the total count when the region is not expanded as show in the attached image. Now I just need to get the count for the clients.

GridGroupByExpression expression1 = GridGroupByExpression.Parse("Region, count(TicketCount) TicketCount [Total Ticket Count] Group By Region");

CustomizeExpression(expression1);

rg1.MasterTableView.GroupByExpressions.Add(expression1);

rg1.DataBind();

private void CustomizeExpression(GridGroupByExpression expression)

{

//avoid adding the total field twice

GridGroupByField existing = expression.SelectFields.FindByName("TicketCount");

if (existing == null) //field is not present

{

//Construct and add a new aggregate field

GridGroupByField field = new GridGroupByField();

field.FieldName = "TicketCount";

field.FieldAlias = "SubTotal";

field.Aggregate = GridAggregateFunction.Sum;

expression.SelectFields.Add(field);

}

else //field is present then set a format string

{

//existing.FormatString = "{0:C}";

}
