[Solved] Codebehind binding with Converter in C#

[jay]

Because I wanted to use multiple instances of the same control I decided to move the below implementation (which works) from xaml to codebehind.

<telerik:GridViewDataColumn

Header="Duration"

DataMemberBinding="{Binding Converter={StaticResource DurationConverter}}"

Width="85"/>



public class DurationConverter: IValueConverter

{

public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)

{

return ((myEntity)value).DurationValue + " " + ((myEntity)value).durationType;

}

public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)

{

throw new NotImplementedException();

}

}



This converter combines two fields to give me something like "3 Weeks" or "5 days"

Now, in my codebehind, I have the following which works for "normal" GridViewDataColumns but not for columns that bind with a static converter.

private void rgvEmpSubControl_Loaded(object sender, RoutedEventArgs e)

{

GridViewDataControl dataControl = (GridViewDataControl)sender;

dataControl.Columns.Clear();

bnd = new Binding();

bnd.Mode = BindingMode.TwoWay;

bnd.Path = new PropertyPath("SelectedItem");

bnd.Source = _viewModel.EmpTrainings;

dataControl.Columns.Add(DataColummParameters("Duration", "abc", 85));

dataControl.SetBinding(GridViewDataControl.SelectedItemProperty, bnd);

}

private GridViewDataColumn DataColummParameters(string _Header, string _Binding, int intWidth)

{

GridViewDataColumn GVDC = new GridViewDataColumn();

GVDC.DataMemberBinding = new Binding(_Binding);

GVDC.Header = _Header;

GVDC.Width = intWidth;

return GVDC;

}

My questions is

how can I structure "abc" to produce the codebehind equivalent of [DataMemberBinding="{Binding Converter={StaticResource DurationConverter}}" ] ?

Hello jay,

You may set the converter in the code-behind as follows:

GridViewDataColumn column = new GridViewDataColumn();
column.DataMemberBinding = new Binding("Gender"){Converter = new GenderConverter()};
this.playersGrid.Columns.Add(column);

Hello, 

 Here is my code xaml.  

<telerik:GridViewDataColumn TextAlignment="Left" IsReadOnly="True"
                Header="Etat" HeaderTextAlignment="Center" Width="*" UniqueName="etat">
      <telerik:GridViewDataColumn.CellTemplate>
          <DataTemplate x:Name="etatCell">
            <StackPanel>
               <Image x:Name="imageEtat" Source="{Binding Mode=OneWay, Converter={StaticResource EtatToImageConverter}}" Width="50" Height="50" />
           </StackPanel>
         </DataTemplate>
      </telerik:GridViewDataColumn.CellTemplate>
</telerik:GridViewDataColumn>

  I want to know how to bind the converter whitch is in the DataTemplate  in the code behind.
