WPF XAML Style markup shortcuts?
Is it possible to write this out in a slicker/shorter way? all it is doing is setting 3 properties and taking too much room IMO..
<Style x:Key="CellStyle" TargetType="{x:Type DataGridCell}" BasedOn="{StaticResource BasicFont}">
<Setter Property="Foreground">
<Setter.Value>
<Binding>
<Binding.Converter>
<local:ForegroundColorConverter />
</Binding.Converter>
</Binding>
</Setter.Value>
</Setter>
<Setter Property="Background">
<Setter.Value>
<Binding>
<Binding.Converter>
<local:ColorConverter />
</Binding.Converter>
</Binding>
</Setter.Value>
</Setter>
<Setter Property="BorderBrush">
<Setter.Value>
<Binding>
<Binding.Converter>
<local:ColorConverter />
</Binding.Converter>
开发者_开发百科 </Binding>
</Setter.Value>
</Setter>
</Style>
Sort of, first you have to define the Converters before the Style:
<local:ColorConverter x:Key="colorConverter" />
Then you can use them as StaticResources in your style:
<Setter Property="BorderBrush" Value="{Binding Converter={StaticResource colorConverter}}" />
Full example
C#:
using System;
using System.Windows;
using System.Windows.Data;
using System.Windows.Media;
namespace WpfApplication1
{
/// <summary>
/// Interaction logic for Window1.xaml
/// </summary>
public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
}
}
// The converter
public class ColorConverter : IValueConverter
{
#region IValueConverter Members
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return Brushes.Red;
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
throw new NotImplementedException();
}
#endregion
}
}
XAML:
<Window x:Class="WpfApplication1.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WpfApplication1"
Title="Window1" Height="300" Width="354">
<Window.Resources>
<local:ColorConverter x:Key="colorConverter" />
<Style TargetType="{x:Type Button}">
<Setter Property="Background" Value="{Binding Converter={StaticResource colorConverter}}" />
</Style>
</Window.Resources>
<Grid>
<Button Margin="8" Content="A button" HorizontalAlignment="Center" VerticalAlignment="Center" />
</Grid>
</Window>
Btw, now that I think about it, not sure if you simplified your code, but you don't actually need a converter for that. You can set a SolidColorBrush instead of a Converter (unless you're doing some code in the converter), something like this:
<Window.Resources>
<SolidColorBrush Color="Red" x:Key="redSolidColorBrush" />
<SolidColorBrush Color="White" x:Key="whiteSolidColorBrush" />
<Style TargetType="{x:Type Button}">
<Setter Property="Background" Value="{StaticResource redSolidColorBrush}" />
<Setter Property="Foreground" Value="{StaticResource whiteSolidColorBrush}" />
</Style>
</Window.Resources>
<Grid>
<Button Margin="8" Content="A button" HorizontalAlignment="Center" VerticalAlignment="Center" />
</Grid>
Try this:
<Style x:Key="CellStyle" TargetType="{x:Type DataGridCell}" BasedOn="{StaticResource BasicFont}">
<Setter Property="Foreground" Value="{Binding Converter={local:ForegroundColorConverter}}"/>
<Setter Property="Background" Value="{Binding Converter={local:ForegroundColorConverter}}"/>
<Setter Property="BorderBrush" Value="{Binding Converter={local:ForegroundColorConverter}}"/>
</Style>
Not sure this is supported (don't have VS right here to test), but try it - that's at least a little less verbose :).
