    What is not working? Do you have any errors in the output window?

    Hi Pankaj,

    When using a Trigger (or DataTrigger) in your Style, the Setter must be set on the Trigger and not on the Style.

    For example :

      Style style = new Style(typeof(Xceed.Wpf.DataGrid.DataRow ));
      DataTrigger styleDataTrigger = new DataTrigger();

      System.Windows.Data.Binding binding = new System.Windows.Data.Binding();
      binding.Path = new PropertyPath("OrderID");
      binding.Source = Orders;

      styleDataTrigger.Binding = binding;
      styleDataTrigger.Value = "10249";

      Setter setter = new Setter(Xceed.Wpf.DataGrid.DataRow.BackgroundProperty, Brushes.Yellow );
      styleDataTrigger.Setters.Add(setter);

      Style.Triggers.Add(styleDataTrigger);

    Re: problem in BackgroundColor of datarow c# code

    I have tried Diane's method as well, but it doesn't seem to work and there are no errors shown in the Output window.  I have put together a sample application demonstrating this method (as well as some others) at this post: http://xceed.com/CS/forums/23510/ShowThread.aspx#23510

    It is invoked by pressing the 'Method 3' button.

    Any assistance with this would be greatly appreciated.

    Many thanks,

    Hi Jason,

    see if the following is make scense.

    Style style = new Style(typeof(Xceed.Wpf.DataGrid.DataRow));

    DataTrigger styleDataTrigger = new DataTrigger();

    System.Windows.Data.Binding binding = new System.Windows.Data.Binding();

    binding.Path = new PropertyPath("MyProp1");

    binding.Source = MyDataList;

    styleDataTrigger.Binding = binding;

    styleDataTrigger.Value = "Val5";

    Setter setter = new Setter(Xceed.Wpf.DataGrid.DataRow.BackgroundProperty, Brushes.Yellow);

    styleDataTrigger.Setters.Add(setter);

    style.Setters.Add(setter);

    style.Triggers.Add(styleDataTrigger);

    dgcMyData.ItemContainerStyle = style;

    ((DataGridCollectionView)this.dgcMyData.ItemsSource).Refresh();

    Hi Suresh,

    I tried this, but all the cells in my DataGrid just appeared yellow.  The Style DataTrigger doesn't seem to have an effect.  However, I have updated the example including this method (Method3) in the following thread, and it looks like I might be getting further doing it via XAML rather than programmatically:
