In my DataGrid, each row contains a RichTextBox.
EDIT : Here is how the RTB is placed in the DataGrid
<DataGrid>
<DataGrid.Columns>
<DataGridTemplateColumn x:Name="columnText" x:Uid="columnText"
Header="Text"
Width="*"
IsReadOnly="True"
SortMemberPath="Text"
CellTemplate="{StaticResource mainFormGridCell_columnText}"/>
</DataGrid.Columns>
</DataGrid>
The DataTemplate is defined in a ResourceDictionary and looks roughly like this :
<DataTemplate x:Key="mainFormGridCell_columnText">
<RichTextBox x:Name="rtbDiff" x:Uid="rtbDiff"/>
</DataTemplate>
What I need to do at runtime is fill the richtextbox of the SelectedItem with a FlowDocument. I now use the extension methods described here to find the Cell that contains that Control. With that I do the following :
DataGridCell cell = this.dgTexts.GetCell( this.dgFreetexts.GetSelectedRow(), 0 );
object ob = cell.Template.FindName( "rtbDiff", cell );
No matter how, I never find any Child with that Name - FindName always returns NULL. Does anybody have any ideas how I can improve my search for the RichTextBox?
Thanks in advance!
