I am trapping the onsign event and performing some actions on the form. I ned to reverse the actions when (if) the form signature is revoked or removed? Is there an event corresponding to that?

You can place an OnAfterChange event handler on the signature node to have your code notified when a change (add / delete / etc) occurs. You'll have to keep track, in code, of the current signature count so that you can compare it against the change in order to know whether an add or delete occurred.

Good luck.

i tried out your suggestion Greg. But for some reason, the OnAfterChange is triggered before the signed state of the form is altered.
I put in a
thisXDocument.UI.Alert(thisXDocument.IsSigned.ToString());
statement at the end of the eventhandler for OnAfterChange and the value in the messagebox is not the final value.
e.g. when signing the form, the box pops up with a 'false' vaue and when removing the signature, it pops up a 'true' value.

So are you signing the entire form or sections within the form?

Entire form

Hi Shukla,
Here is how you can find out
In the OnAfterChangeEvent, get the signeddatablock and look for the count of signatutes on the block. This will tell you if the form is signed or unsigned.

SignedDataBlock signedDataBlock = thisXDocument.SignedDataBlocks[0];
signedDataBlock.Signatures.Count;
this will give you the number of signatures on the given block.

I hope this helps!

I did and that's the interesting thing. When the OnAfterChangeEvent id generated (on the user doing a remove sign action), the form is still signed.
