---|---|
GridColumn | A GridColumn class descendant that specifies the unbound column currently being processed. |
Example
Assume that the DataGridView instance is bound to a collection of orders. An order has the Product.Name, Product.UnitPrice and Quantity fields. This example shows how to add an unbound column (Total) to the grid to calculate each order amount according to the expression: UnitPrice*Quantity.
Implement logic to calculate column values in one of the following ways:
- Use the GridColumn.UnboundExpression property:
<dxg:DataGridView x:Name="grid" ItemsSource="{Binding Orders}">
<dxg:DataGridView.Columns>
<dxg:TextColumn FieldName="Product.Name" Caption="Product" Width="170" />
<dxg:NumberColumn FieldName="Product.UnitPrice" Caption="Price" DisplayFormat="C0"/>
<dxg:NumberColumn FieldName="Quantity"/>
<dxg:NumberColumn FieldName="Total" UnboundType="Integer"
UnboundExpression="[Quantity] * [Product.UnitPrice]"
IsReadOnly="True" DisplayFormat="C0"/>
</dxg:DataGridView.Columns>
</dxg:DataGridView>
- Use the DataGridView.CustomUnboundColumnData event:
<dxg:DataGridView x:Name="grid" ItemsSource="{Binding Orders}" CustomUnboundColumnData="Grid_CustomUnboundColumnData">
<dxg:DataGridView.Columns>
<dxg:TextColumn FieldName="Product.Name" Caption="Product" Width="170" />
<dxg:NumberColumn FieldName="Product.UnitPrice" Caption="Price" DisplayFormat="C0"/>
<dxg:NumberColumn FieldName="Quantity"/>
<dxg:NumberColumn FieldName="Total" UnboundType="Integer"
IsReadOnly="True" DisplayFormat="C0"/>
</dxg:DataGridView.Columns>
</dxg:DataGridView>
