how to change opacity of disabled GridControl Rows

created 2 months ago

Hello support,

when i disable rows in a GridControl, they appear to have lower opacity.
How can i change the opacity?
A simple style setter is not working:

XAML
<dxg:TableView>
    <dxg:TableView.RowStyle>
        <Style TargetType="dxg:RowControl">
            <Setter Property="ToolTipService.ShowOnDisabled" Value="True" />
            <Setter Property="ToolTip" Value="disabled" />
            <Setter Property="IsEnabled" Value="False" />
            <Setter Property="Opacity" Value="1" />
        </Style>
    </dxg:TableView.RowStyle>
    <dxg:TableView.FormatConditions>
        <dxg:FormatCondition Expression="true"
                             PredefinedFormatName="StrikethroughText" />
    </dxg:TableView.FormatConditions>
</dxg:TableView>

Hello Norman,

Thank you for the sample project.

The most straightforward way to accomplish this task is to make cells read-only instead of disabling the row control:

XAML
<dxg:TableView.CellStyle>
    <Style TargetType="dxg:LightweightCellEditor">
        <Setter Property="ReadOnly" Value="True" />
    </Style>
</dxg:TableView.CellStyle>

Please let me know if this meets your requirements.

Regards,
Alexander

      Hello Norman,

      Thank you for keeping us updated.

      After inspecting the application with the Snoop tool, I discovered that the opacity of the target editor can be affected via the EditorOpacity property. For this, it should be sufficient to implement a custom CellStyle as follows:

      XAML
      <dxg:TableView.CellStyle>
    <Style TargetType="{x:Type dxg:LightweightCellEditor}">
        <Setter Property="EditorOpacity" Value="1"/>
    </Style>
</dxg:TableView.CellStyle>

      Please try a similar approach and let me know if it works for you.
