Question

我有一个带有ComboboxEdit CellTemplate的两列的Devexpress DxGrid

<dxg:GridControl Name="grid">
    <dxg:GridControl.Columns>
       <dxg:GridColumn FieldName="Size_ID" CellTemplate="{DynamicResource DimensionComboBox}"/>
       <dxg:GridColumn FieldName="Color_ID" CellTemplate="{DynamicResource DimensionComboBox}"/>
    </dxg:GridControl.Columns>
</dxg:GridControl>

在我的app.xaml中我定义了一个模板

<DataTemplate x:Key="DimensionComboBox" >
                <dxe:ComboBoxEdit x:Name="PART_Editor"  DisplayMember="Grp_Property_Desc" ValueMember="Grp_Property_ID" >
                    <dxe:ComboBoxEdit.ItemsSource>
                        <Binding Path="Data">
                            <Binding.Converter>
                                <local:GridComboBoxItemSourceConverter/>
                            </Binding.Converter>
                        </Binding>
                    </dxe:ComboBoxEdit.ItemsSource>
                </dxe:ComboBoxEdit>
            </DataTemplate>

我想知道我的转换器中的列字段名称，以便我根据调用转换器的列返回数据

Public Class GridComboBoxItemSourceConverter
    Implements IValueConverter

#Region "IValueConverter Members"

    Public Function Convert(ByVal value As Object, ByVal targetType As Type, ByVal parameter As Object, ByVal culture As System.Globalization.CultureInfo) As Object Implements IValueConverter.Convert

'if field name is color_id then return data for color_id

'if field name is size_id then return data for size_id

    End Function

    Public Function ConvertBack(ByVal value As Object, ByVal targetType As Type, ByVal parameter As Object, ByVal culture As System.Globalization.CultureInfo) As Object Implements IValueConverter.ConvertBack
        Throw New NotImplementedException()
    End Function
#End Region
End Class

有没有办法在不必为每列创建转换器类的情况下完成此操作，我还有许多其他要转换的列。

Answer 1

您可以为每列创建数据窗口，并在转换器参数

中指定列名称

从IvalueConverter转换函数中获取DxGrid Column FieldName
