[Solved] Bind Grid Datatable using Boolean Converter

[Jayesh Valla]

Hi,

I seem to have a small problem when data binding a RadGridView Control with a Data Table via a Boolean Converter. The scenario is as follows .... I have  a DataTable of which one of the columns is of type Boolean. I would like to convert the True value to YES and False to NO. When I bind the DataColumn of the grid via a Converter class, no value is displayed. However, when I click on the filter icon of the column I can filter by YES and NO. I have gone through the forums and documentation and applied the solutions to similar problems with no success.

Converter Class

   [ValueConversion(typeof(Boolean), typeof(String))]
   class IsWhiteAreaConverter : IValueConverter
   {
       public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
       {
           return (bool)value ? "Yes" : "No";
       }

       public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
       {
           if ((string)value == "Yes")
           {
               return true;
           }
           else
           {
               return false;
           }
       }
   }

XAML

  <Grid.Resources>

            <my:IsWhiteAreaConverter x:Key="isWhiteAreaConverter" />

        </Grid.Resources>

 

 

 

 <telerik:RadGridView Grid.Column="0" Grid.Row="0" Grid.ColumnSpan="2" Name="rgvPlan" ItemsSource="{Binding}" AutoGenerateColumns="False">

      <telerik:GridViewDataColumn Header="HalfLevel" DataMemberBinding="{Binding HalfLevelName}" />

<telerik:GridViewDataColumn Header="Is White Area" DataMemberBinding="{Binding IsWhiteArea, Converter={StaticResource isWhiteAreaConverter}}">

      <telerik:GridViewDataColumn.CellTemplate>

             <DataTemplate>

                      <TextBlock Text="{Binding IsWhiteArea, Converter={StaticResource isWhiteAreaConverter}, Mode=Default}" Foreground="AliceBlue" />

             </DataTemplate>

      </telerik:GridViewDataColumn.CellTemplate>

      <telerik:GridViewDataColumn.CellEditTemplate>

              <DataTemplate>

                     <TextBox Text="{Binding IsWhiteArea, Converter={StaticResource isWhiteAreaConverter}}" />

              </DataTemplate>

      </telerik:GridViewDataColumn.CellEditTemplate>

</telerik:GridViewDataColumn>
