Re: Add Signature link disappeared after removed signature programmatically

Any idea what is the appropriate way to remove a signature programatically?

Hi Willy Loman,

I don't think the signatures were meant to be removed in that way. You will invalidate the form and that may be the reason why it's broken.

Using the following code I can remove a signature.

Dim xnDoc As XPathNavigator = MainDataSource.CreateNavigator()

If (Me.Signed) Then 'unsign it

Dim xSignedSection As XPathNavigator = xnDoc.SelectSingleNode("my:meineFelder/my:signaturen1/my:signaturen2", Me.NamespaceManager)

If (xSignedSection.HasChildren) Then

xSignedSection.MoveToChild(XPathNodeType.Element)

xSignedSection.DeleteSelf()

Me.CurrentView.ForceUpdate()

End If

But after this procedure the link "click here to...." under the regarding group disappears.

ForceUpdate() shows no effect.

If open the menu 'Tools / Digital Signatures' or 'File / Save' the link appears in the form again.

Does anybody has a clue?
