wpf DataGrid disable cell edit for specific row except first column

I have a binding to a generic DataTable where some rows may contain problems and should not be modified. There seems to be a very easy way to accomplish that by simple setting IsEnabled in DataGrid_LoadingRow or by a Trigger with Binding in XAML. However, I also have a “Info”-Column which has a Button in it so that the user can view the problem… Setting IsEnabled to false also disables my button… I already tried: IsManipulationEnabled but this has no effect. How can I accomplish this? Is the only way for doing that by traversing the VisualTree of the DataRowView and set IsEnabled for all Cells except the first?

For your first column, use this Button,

public class EnabledButton : Button
{
    static EnabledButton()
    {
        UIElement.IsEnabledProperty.OverrideMetadata(typeof(EnabledButton),
                new FrameworkPropertyMetadata(true, FrameworkPropertyMetadataOptions.None,
                    UIElement.IsEnabledProperty.DefaultMetadata.PropertyChangedCallback,
                    new CoerceValueCallback(IsEnabledCoerceCallback)));
    }

    private static object IsEnabledCoerceCallback(DependencyObject d, object baseValue)
    {
        return (bool)baseValue;
    }
}

Usage : 

<DataGrid.Columns>
    <DataGridTemplateColumn>
        <DataGridTemplateColumn.CellTemplate>
            <DataTemplate>
                <local:EnabledButton IsEnabled="True" Content="Modify"/>
            </DataTemplate>
        </DataGridTemplateColumn.CellTemplate>
    </DataGridTemplateColumn>
    ...
</DataGrid.Columns>

This overrides the inheritance of DataGridCell.IsEnabled property.
