Hi there telerik team,
I'm using the RadRichTextBox with a RtfFormatProvider inside a RadGridView column like this:
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:
Have you seen such problems before?
Regards
Christian Kleinheinz
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

</

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:
