Apply filter on DatagridTemplateColumn

[Ja7373]

Hello All,
I want to filter a DataGridTemplateColumn
How can I apply the filter on these columns?

<DataGridTemplateColumn Width="Auto">
      <DataGridTemplateColumn.Header>
        <TextBlock Text="Name" FontWeight="Bold" Margin="5 0"/>
      </DataGridTemplateColumn.Header>
      <DataGridTemplateColumn.CellTemplate>
        <DataTemplate>
          <TextBlock Text="{Binding Name}" Margin="5 0"/>
        </DataTemplate>
      </DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>

Thanks.

Hi @tom-englert, is the MultipleChoiceFilter also working with DataGridTemplateColumn?
I checked with the "Basic-Sample":
with the example implementation - a text column - the filter gets updated as the column value changes.

DataGridExtensions/src/BasicSample/MainWindow.xaml

Line 20 in 17a6ae3

<DataGridTextColumn Header="Multiple" Binding="{Binding Column5}" dgx:DataGridFilterColumn.Template="{StaticResource MultipleChoiceFilter}"/>

When I'm replacing this column / line with a template column according to the syntax as in the other example:
<!-- A template column may contain everything, so we need to specify the SortMemberPath explicitly...--> <DataGridTemplateColumn Header="Template" SortMemberPath="Column5" dgx:DataGridFilterColumn.Template="{StaticResource MultipleChoiceFilter}"> <DataGridTemplateColumn.CellTemplate> <DataTemplate DataType="{x:Type basicSample:DataItem}" > <TextBox Margin="2" Text="{Binding Column5}"/> </DataTemplate> </DataGridTemplateColumn.CellTemplate> </DataGridTemplateColumn>

The Dropdown Values don't get updated when I'm changing values in the cell.
Am I missing some event bindings / etc that need to be made additionally for a template column?

This comment would be great in Filter / Sort documentation. Thanks!
" A template column may contain everything, so we need to specify the SortMemberPath explicitly.."
