Remarks

To display the results of a statistical function it is suggested to set the ResultPropertyName of the StatCell rather than binding the content.

Although the result of a statistical function can be displayed in other elements (e.g., TextBlock), using a StatRow allows the results of statistical functions to be arranged in a similar fashion as the other cells in a grid.

Example

All examples in this topic assume that the grid is bound to the Orders table of the Northwind database, unless stated otherwise.

The following example demonstrates how to display the results of various statistical functions in and outside of a grid.

XAML

<Grid xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid">

  <Grid.Resources>

    <xcdg:DataGridCollectionViewSource x:Key="cvs_orderdetails"

                                                        Path=OrderDetails}">

     <xcdg:DataGridCollectionViewSource.StatFunctions>

       <xcdg:CountFunction ResultPropertyName="orderid_count"

                           SourcePropertyName="OrderID"/>

       <xcdg:SumFunction ResultPropertyName="unitprice_sum"

                         SourcePropertyName="UnitPrice"/>
