DataGrid

Hi Community,

I've set a own Class-Object to my DataContext.

this Object contains a Property called "MergedGerman", Type: System.Data.DataTable.

In each Cell of this DataTable, there is no simple string, but a own created class-object called "Text".

This Text-Class contains a "Caption" property, Type: System.String

public class Text: DependencyObject
{
   public static readonly DependencyProperty CaptionProperty =
   DependencyProperty.Register("Caption", typeof(string), typeof(Text));


   public string Caption
   {
      get { return (string)GetValue(CaptionProperty); }
      set { SetValue(CaptionProperty, value); }
   }

   // other Properties
   // ....
}

I've bound a dataGrids ItemSource to the "MergedGerman"-Property of my DataContext

<DataGrid x:Name="Dgrid_Original" Margin="0,5,0,0" Width="198"  AutoGeneratingColumn="Dgrid_Original_AutoGeneratingColumn"  ItemsSource ="{Binding Path=MergedGerman}">
</DataGrid>

My DataGrid displays the Text-Object by using the ToString()-Method.

But I want to display the Caption-Property of my Text-Object.

How works it ?


I've tried the following:

1.)

<DataGrid x:Name="Dgrid_Original" Margin="0,5,0,0" Width="198"  AutoGeneratingColumn="Dgrid_Original_AutoGeneratingColumn"  ItemsSource ="{Binding Path=MergedGerman}">

<DataGrid.Columns>
   <DataGridTextColumn Header="Test" Binding="{Binding Caption}"/>
</DataGrid.Columns>
</DataGrid>

2.)

<DataGrid x:Name=quot;Dgrid_Original" Margin=&
quot;0,5,0,0" Width="198"  AutoGeneratingColumn="Dgrid_Original_AutoGeneratingColumn"  ItemsSource ="{Binding Path=MergedGerman}">

<DataGrid.Columns>
   <DataGridTemplateColumn Header="Test">
      <DataGridTemplateColumn.CellTemplate>
      <DataTemplate>
         <TextBox Text="{Binding Caption}"/>
      </DataTemplate>
      </DataGridTemplateColumn.CellTemplate>
   </DataGridTemplateColumn>
</DataGrid.Columns>
</DataGrid>

The result of 1.) and of 2.) is a empty textbox :-(

Do you have an idea ?
