Examples

This example demonstrates how to use predefined aggregate functions and custom rule to calculate group and total summaries for grid columns.

Data Summaries

  • Set the group summary to display the maximum Total value for each group of records.
  • Set the total summary to calculate the sum of values in the Total column.
  • Set the custom total summary to count the number of orders whose value in the Shipped column is false (to count orders that are not shipped).
<dxg:DataGridView x:Name="grid" ItemsSource="{Binding Orders}" 
                 CalculateCustomSummary="OnCalculateCustomSummary">
    <!-- ... -->
    <dxg:DataGridView.GroupSummaries>
        <dxg:GridColumnSummary FieldName="Total" Type="Max"/>
    </dxg:DataGridView.GroupSummaries>

    <dxg:DataGridView.TotalSummaries>
        <dxg:GridColumnSummary FieldName="Total" Type="Sum" 
                               DisplayFormat="Total: {0:C0}"/>
        <dxg:GridColumnSummary FieldName="Shipped" Type="Custom" 
                               DisplayFormat="Not Shipped: {0}"/>
    </dxg:DataGridView.TotalSummaries>
