How do I underline text between two given offsets in the EditControl ?


Please refer to the code snippets and the test sample attached below that illustrates how this can be done.


// Starting offset converted to virtual point

Point pt1 = this.editControl1.ConvertOffsetToVirtualPosition(inputDialog.Point1);

// Ending offset converted to virtual point

Point pt2 = this.editControl1.ConvertOffsetToVirtualPosition(inputDialog.Point2);

this.editControl1.SetSelection(pt1.X, pt1.Y, pt2.X, pt2.Y);

ISnippetFormat format = editControl1.RegisterUnderlineFormat(Color.Red, UnderlineStyle.Wave, UnderlineWeight.Thick);

this.editControl1.SetUnderline (this.editControl1.Selection.Top, this.editControl1.Selection.Bottom, format);



' Starting offset converted to virtual point

Dim pt1 As Point = Me.editControl1.ConvertOffsetToVirtualPosition(inputDialog.Point1)

' Ending offset converted to virtual point

Dim pt2 As Point = Me.editControl1.ConvertOffsetToVirtualPosition(inputDialog.Point2)

Me.editControl1.SetSelection(pt1.X, pt1.Y, pt2.X, pt2.Y)

Dim format As ISnippetFormat = editControl1.RegisterUnderlineFormat(Color.Red,UnderlineStyle.Wave,UnderlineWeight.Thick)

Me.editControl1.SetUnderline (Me.editControl1.Selection.Top, Me.editControl1.Selection.Bottom, format)
