For now what I am doing is testing the RichTextbox1.Text value and saving an empty string if that is the case in the the bo.BeforeSave(), of course if would be nice to have this test be done in this SF RichTextbox class instead. Private Sub BizCompany1_BeforeSave(ByVal e As MicroFour.StrataFrame.Data.BeforeSaveUndoEventArgs) Handles BizCompany1.BeforeSave '-- Check if the RTF value is empty, and remove any RTF meta code If String.IsNullOrWhiteSpace(Me.RichTextbox1.Text) Then Me.BizCompany1.QuickOrderFooter = String.Empty End If End Sub Edhy Rijo

The Rtf property is never empty, you always have to test on the Text. Because of this, we have implemented some utility methods in our other applications like so: ''' <summary> ''' Converts an RTF formatted string into plain text ''' </summary> Public Shared Function RtfToText(ByVal rtf As String) As String '-- Establish Locals Using rtfCtrl As New System.Windows.Forms.RichTextBox() Dim r As String = "" '-- Set the text rtfCtrl.Rtf = rtf '-- Get the rtf code r = rtfCtrl.Text '-- Return the results Return r End Using End Function This allows us to pass an RTF string and the RichTextBox will convert it to a regular string for us so we can we can view the raw text (and even test if it's empty).
