Missing PART in the datagrid

[TheCamel]

the "PART_FillerColumnHeader" in not present in the template

Create a new projet with a datagrid, columns and parse the xaml = at the end of the headers, this PART is filling the rest of the header grid.

I was using this in my code to remove a custom filter control in the last part var filler = VisualHelper.FindChild<DataGridColumnHeader>(this, "PART_FillerColumnHeader");

you can also modify the header style to verify - below the original datagrid

<Style x:Key="DataGridColumnHeadersPresenterStyle1" TargetType="{x:Type DataGridColumnHeadersPresenter}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type DataGridColumnHeadersPresenter}"> <Grid> <DataGridColumnHeader x:Name="**PART_FillerColumnHeader**" IsHitTestVisible="False"/> <ItemsPresenter/> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style>
