  I'm trying to use the RadGridView AggregateFunctions. I've tested Count, Min and Max functions successfully. However, when I try using SumFunction or AverageFunction, nothing is displayed on the column footer (including the previously added Count, Min, Max functions).

  
  

  I'm binding a DataTable to the grid from C# like this:

  
  

  this.radGrid1.ItemsSource = dtData;

  
  

  This is the XAML for the GridView:

  
  

  <telerikGrid:RadGridView

  x:Name="radGrid1"

  MultipleSelect="True"

  AutoGenerateColumns="False"

  ShowColumnFooters="True" ShowGroupFooters="True">

  <telerikGrid:RadGridView.Columns>

  <telerikGrid:GridViewDataColumn Header="AccountNo" DataMemberBinding="{Binding AccountNo}">

  <telerikGrid:GridViewDataColumn.AggregateFunctions>

  <telerikData:CountFunction Caption="Count:" />

  </telerikGrid:GridViewDataColumn.AggregateFunctions>

  </telerikGrid:GridViewDataColumn>

  <telerikGrid:GridViewDataColumn Header="InvestmentCost" DataMemberBinding="{Binding InvestmentCost}" DataFormatString="{}{0:c}" TextAlignment="Right">

  <telerikGrid:GridViewDataColumn.AggregateFunctions>

  <telerikData:SumFunction ResultFormatString="{}{0:c}" SourceField="InvestmentCost" />

  <telerikData:MinFunction ResultFormatString="{}{0:c}" SourceField="InvestmentCost" />

  <telerikData:MaxFunction ResultFormatString="{}{0:c}" SourceField="InvestmentCost" />

  </telerikGrid:GridViewDataColumn.AggregateFunctions>

  </telerikGrid:GridViewDataColumn>

  </telerikGrid:RadGridView.Columns>

  </telerikGrid:RadGridView>

  
  

  Edit: 

  DataType for InvestmentCost column in dtData is Decimal.

  I'm using RadControls for WPF Q3 2009 SP1

  Hello Jeffrey Lewis,
  
  I have tried to reproduce the problem here but with my test project it seems to work ok .
  Please find the test project attached .  Maybe I am missing something to be able to  reproduce the problem ?

  Thanks, got it to work following your example. The problem was I didn't put this in my SumFunction.

  
  

  SourceFieldType="{x:Type s:Decimal}"
