DevExpress GridControl cell enabling/disabling

Question

I have a grid control where some columns are editable, some are not.

I'd like to have more fine control, so that depending on some other fields of MyData, the corresponding cells will be enabled or not.

    <dxg:GridControl ItemsSource="{Binding MyData}" AutoPopulateColumns="True">
            <dxg:GridControl.Columns>
                <dxg:GridColumn Header="Name" ReadOnly="True"/>
                <dxg:GridColumn Header="ID 1" ReadOnly="False"/>
                <dxg:GridColumn Header="ID 2" ReadOnly="False"/>
                <dxg:GridColumn Header="ID 3" ReadOnly="False"/>
        </dxg:GridControl.Columns>
   </dxg:GridControl>

Can't find anything on the DevExpress support site yet. Would you please have any idea?

Thank you!

You can accomplish this task via handling the ShowingEditor event. You can set e.Cancel to True if a cell shouldn't be edited:

void TableView_ShowingEditor(object sender, DevExpress.Xpf.Grid.ShowingEditorEventArgs e)
{
    if(...)
    {
        e.Cancel = true;
    }
}

You can also accomplish this task via XAML style:

<Style TargetType="dxg:CellContentPresenter" BasedOn="{StaticResource {dxgt:GridRowThemeKey ResourceKey=CellStyle}}">
    <Setter Property="IsEnabled" Value="{Binding Path=RowData.Row.SomePropertyRelatedToEnabledState}"/>
</Style>
