TextAlignment in editing mode for RadGridView

[Alice]

In a WPF project using Telerik, I have a RadGridView where I’ve centered the text alignment. This works perfectly in normal mode, but during editing, the text reverts to left alignment.
How can I change the text alignment in editing mode for RadGridView, preferably through XAML?

I have checked this by setting the TextAlignment of the column to Center. In my case the text is centered also in edit mode. You can see this in the attached project.

Keep in mind that the TextAlignment setting won't take effect automatically if you replace editor of the column (via the CellEditTemplate property or by overridding the column's CreateCellEditElement method). You should handle the alignment manually in this scenario. Here is one way to do this:

<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" TextAlignment="Center" Width="100">
    <telerik:GridViewDataColumn.CellEditTemplate>
        <DataTemplate>
            <TextBox Text="{Binding Name, Mode=TwoWay}" TextAlignment="{Binding RelativeSource={RelativeSource AncestorType=telerik:GridViewCell}, Path=Column.TextAlignment}" />
        </DataTemplate>
    </telerik:GridViewDataColumn.CellEditTemplate>
</telerik:GridViewDataColumn>

@Martin Ivanov thank you for your detailed explanation.

In the approach you showed, I would need to modify the CellEditTemplate, creating a custom DataTemplate for each column in all RadGridViews throughout my application.
Instead, I am looking for a centralized way to apply this change, such as by applying a style to the GridViewRow:

<Style TargetType="{x:Type telerik:GridViewRow}">
    <Setter Property="HorizontalAlignment" Value="Stretch" />
    <Setter Property="TextBlock.TextAlignment" Value="Center" />
</Style>

This approach successfully centers the text in normal mode, but it does not work during cell editing. I also tried setting HorizontalAlignment="Center" for the GridViewCell without success.

Which Control should I apply the style to in order to ensure that all cells in all RadGridViews in my application are centered during editing?

Hey Alice

I've shown the CellEditTemplate approach only if you already use this template. I am not suggesting to use CellEditTemplate as a solution. My point was that the TextAlignment setting of the column is automatically applied also in the editor element and if this doesn't work probably something in the application logic is overriding this behavior.

If you send over a sample project showing the issue, I can check what could be causing this and suggest a more specific approach.
