  DataGrid: How to change cell foreground after LoadingRow?

  Jan 06, 2009 07:19 AM | LINK

  In the post: http://silverlight.net/forums/t/42372.aspx I make cell foreground change. After that, when the data in cell is changed, I need change foreground again. But the LoadingRow can not be raising after first load. Does anyone have a good way to do this?

   thanks

  Thank preishuber.

  Finnally, I use Foreground Binding a property in my dataclass

  In my data class, add ForeColor

      public class MyData : INotifyPropertyChanged
      {
          #region Static Brush
  
          private static Brush _highPriceBrush;
          public static Brush HighPriceBrush
          {
              get
              {
                  if (null == _highPriceBrush)
                      _highPriceBrush = new SolidColorBrush(Colors.Red);
                  return _highPriceBrush;
              }
              set { _highPriceBrush = value; }
          }
  
          private static Brush _lowPriceBrush;
          public static Brush LowPriceBrush
          {
              get
              {
                  if (null == _lowPriceBrush)
                      _lowPriceBrush = new SolidColorBrush(Colors.Blue);
                  return _lowPriceBrush;
              }
              set { _lowPriceBrush = value; }
          }
  
          #endregion
  
          private float _price;
          public float Price
          {
              get { return _price; }
              set
              {
                  _price = value;
                  PropertyChanged(this, new PropertyChangedEventArgs("Price"));
                  PropertyChanged(this, new PropertyChangedEventArgs("ForeColor"));
              }
          }
  
          public Brush ForeColor 
          {
              get
              {
                  if (Price > 100.0f)
                      return _highPriceBrush;
                  else
                      return _lowPriceBrush;
              }
          }
  
          #region INotifyPropertyChanged
  
          public event PropertyChangedEventHandler PropertyChanged;
  
          #endregion
  
      }
  

   in Page.XAML like this:

                      <data:DataGridTemplateColumn Header="Price" IsReadOnly="True">
                          <data:DataGridTemplateColumn.CellTemplate>
                              <DataTemplate>
                                  <TextBlock Text="{Binding Price}" Foreground="{Binding ForeColor}" HorizontalAlignment="Right" VerticalAlignment="Center" Margin="5,0,5,0"/>
                              </DataTemplate>
                          </data:DataGridTemplateColumn.CellTemplate>
                      </data:DataGridTemplateColumn>
  

   

  It works, but I think it is not a best way.
