I have a WPF application which contains a Datagrid consisting of a column of buttons. The respective XAML code is as follows.

<DataGridTemplateColumn Header="Closed" Width="60">

    <DataGridTemplateColumn.CellTemplate>

        <DataTemplate>

            <Button>

                <Button.Content>

                    <Image>

                        <Image.Source>

                            <MultiBinding Converter="{StaticResource ImageConverter}"

                                  ConverterParameter="Closed">

                                <Binding Path="IsClosed"/>

                                <Binding Path="DataContext.TickImage" RelativeSource="{RelativeSource AncestorType={x:Type UserControl}}"/>

                                <Binding Path="DataContext.CrossImage" RelativeSource="{RelativeSource AncestorType={x:Type UserControl}}"/>

                            </MultiBinding>

                        </Image.Source>

                    </Image>

                </Button.Content>

                <Button.Command>

                    <Binding Path="DataContext.ClosedClicked" RelativeSource="{RelativeSource FindAncestor, AncestorType={x:Type UserControl}}"/>

                </Button.Command>

            </Button>

        </DataTemplate>

    </DataGridTemplateColumn.CellTemplate>

</DataGridTemplateColumn>

The TickImage and CrossImage are image sources either of which is selected based on the value of IsClosed . Now in the ViewModel I need to write a code to toggle images(b/w TickImage and CrossImage ) when the button is clicked. In other words, I need a way to simultaneously bind the Button with an ICommand and a BitmapImage variable.

Please help!!
