  • WPF Snippet - Detecting Binding Errors
    10/08/2009 - 17:39

    I added a reference to this error tracer to the SOTC_DataGridExample tutorial, also on your site.

        public Window1()
        {
            SOTC_BindingErrorTracer.BindingErrorTraceListener.SetTrace();

          _GameData = new DataTable();
          _GameData.Columns.Add(new DataColumn("Game Name", typeof(string)));
          _GameData.Columns.Add(new DataColumn("Creator", typeof(string)));
          _GameData.Columns.Add(new DataColumn("Publisher", typeof(string)));
          _GameData.Columns.Add(new DataColumn("On Xbox", typeof(bool)));

    When I executed the project I get an exception.

    InvalidOperationException:
    Dispatcher processing has been suspended, but messages are still being processed.

    on line 54:

          MessageBox.Show(final, "Binding Error", MessageBoxButton.OK, MessageBoxImage.Error);

    Here is the content of the "final" string:
    System.Windows.Data Error: 39 : BindingExpression path error: 'Publisher' property not found on 'object' ''Object' (HashCode=27253481)'. BindingExpression:Path=Publisher; DataItem='Object' (HashCode=27253481); target element is 'TextBlockComboBox' (Name=''); target property is 'SelectedItem' (type 'Object')

    What do you suggest?
