Access column properties from header style

[Pablo]

Hello team,

I'm trying to acces IsReadOnly property from header style to change its foreground color. For now, I didn't find a solution. I'm trying the following:

<Style x:Key="GridViewHeaderCellStyle" TargetType="{x:Type telerik:GridViewHeaderCell}">

...

<Style.Triggers>
            <DataTrigger Binding="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type telerik:GridViewDataColumn}}, Path=Column.IsReadOnly}" Value="false">
                <Setter Property="Foreground" Value="{DynamicResource primaryBrush}" />
            </DataTrigger>
        </Style.Triggers>
    </Style>

Hello Pablo,

To achieve the desired behavior, you should set the RelativeSourceMode to Self. For reference, please take a look at code snippet below:

<telerik:RadGridView.Resources>

                <Style TargetType="{x:Type telerik:GridViewHeaderCell}">

                    <Style.Triggers>

                        <DataTrigger Binding="{Binding RelativeSource={RelativeSource Mode=Self}, Path=Column.IsReadOnly}" Value="True">

                            <Setter Property="Foreground" Value="Red" />

                        </DataTrigger>

                    </Style.Triggers>

                </Style>
</telerik:RadGridView.Resources>

I hope that this helps.
