    Hi there telerik team,

    I'm using the RadRichTextBox with a RtfFormatProvider inside a RadGridView column like this:

    <telerikGrid:GridViewDataColumn Header="Notes" Name="colNoteText" IsReadOnly="True" IsFilterable="False" IsGroupable="False" IsSortable="False">
          <telerikGrid:GridViewDataColumn.CellTemplate>
              <DataTemplate>
                  <Grid>
                      <telerikDocumentsRtf:RtfDataProvider Name="rtfDataProvider"
                             Rtf="{Binding Path=Note, Mode=TwoWay}"
                             RichTextBox="{Binding ElementName=TextBoxNote}" />
     
                      <telerik:RadRichTextBox Name="TextBoxNote" >
                      </telerik:RadRichTextBox>
                  </Grid>
              </DataTemplate>
          </telerikGrid:GridViewDataColumn.CellTemplate>
      </telerikGrid:GridViewDataColumn>

    The RTF text is displayed as expected. But when I'm sorting the grid based on other columns where the DataMemberBinding was set, the application is terminated with this exception:

    Hi Christian,

    Yes, unfortunately there is such an issue when sorting RadGridView with RadRichTextBox in one of the columns. We will look into the problem and hopefully, fix it soon. As a workaround, you can create a custom control that updates the document when the Text property is changed, and updates the document when the Text property which it is bound to changes its value.
    Please, find attached a sample project illustrating the approach.
    I hope this helps.

    Best wishes,
    Iva

    this: control.Dispatcher.BeginInvoke(new Action(() => { control.richTextBox.Document = document; }),DispatcherPriority.Background);

    makes your GUI much less freezing.
