New Post: Applying Styles to each column in Grid Dynamically

Hi,

1) If you want to apply a red foreground color only to the cell with Value equals "CC" in Column Firstname, you can use a DataTrigger in the "test1Template" :

<DataTemplate x:Key="test1Template">
                  <TextBlock x:Name="_textBlock"
                             Text="{Binding}"
                             Foreground="{Binding Foreground, Source={StaticResource View1}}"/>
                  <DataTemplate.Triggers>
                     <DataTrigger Binding="{Binding Path=.}"
                                  Value="CC">
                        <Setter Property="Foreground"
                                Value="Red" 
                                TargetName="_textBlock"/>
                     </DataTrigger>
                  </DataTemplate.Triggers>
</DataTemplate>

If you want to apply it to all the cells that contains "CC", you can use a converter in the binding of the DataTrigger to get them.

2) I tried it with FontSize, and it worked :

<DataTemplate x:Key="test1Template">
                  <TextBlock Text="{Binding}"
                             Foreground="{Binding Foreground, Source={StaticResource View1}}"
                             FontSize="{Binding FontSize, Source={StaticResource View1}}"/>
</DataTemplate>

 public class MyViewModel : DependencyObject
  {
    //.....

    public double FontSize
    {
      get
      {
        return ( double )GetValue( FontSizeProperty );
      }
      set
      {
        SetValue( FontSizeProperty, value );
      }
    }

    public static readonly DependencyProperty FontSizeProperty = DependencyProperty.Register( "FontSize", typeof( double ), typeof( MyViewModel ),
                                                                  new UIPropertyMetadata( 11d ) );
  }

private void Button_Click( object sender, RoutedEventArgs e )
    {
      MyViewModel viewModel = this.Resources[ "View1" ] as MyViewModel;
      if( viewModel != null )
      {
        viewModel.Foreground = new SolidColorBrush(Colors.Yellow);
        viewModel.FontSize = 20d;
      }
    }
