Bind the entire row object to a single column
posted

Hi,

I am using xamwebgrid. In the grid I want to show an image column so I am using the TemplateColumn and applying datatemplate that contains four images. Now based on two properties in my Object that is bound to the row, I want to show only two of the images.

I can use a value converter to show/hide the images. The only problem is I can bind my column to only one property in my Object. So in the valueconverter I can pass only one property as multibinding is not present in silverlight.

Is there anyway I can bind my entire Object out of the List to one column. That way I can write all the show/hide logic in a single valueconverter.

    Hi,

    You can pass the entire object to the value converter like that:

    <ig:XamGrid>
	<ig:XamGrid.Resources>
		<local:MyConv x:Key="MyConv" />
	</ig:XamGrid.Resources>
	<ig:XamGrid.Columns>
		<ig:TemplateColumn Key="MyColumnKey">
			<ig:TemplateColumn.ItemTemplate>
				<DataTemplate>
					<Image ... other settings ...
						   Visibility="{Binding Converter={StaticResource MyConv}}" />
				</DataTemplate>
			</ig:TemplateColumn.ItemTemplate>
		</ig:TemplateColumn>
	</ig:XamGrid.Columns>

    public class MyConv : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        return [... condition ...] ? Visibility.Visible : Visibility.Collapsed;
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        return DependencyProperty.UnsetValue;
    }
}
