Hi Jimmy, when I open a form it also loads the method of the DropDown change (public void drpChantier_Changed(object sender, XmlEventArgs e)). Can you give me a hand on avoiding that? thanks

Thanks Jimmy. That's what I decided to do and it works just fine.

There isn't a way to turn an OnChange event off and on dynamically. You can, however, add logic to the event that inspects the form's XML and only runs the relevant code only under a certain condition.

Is it possible to disable the code I've written for an onchange event and then re-enable it?

I've got a browser based form that populates a repeating table with a set of questions. The user can then select an answer from a list (Yes, No, N/A). Yes is the default answer. I then write the answers with the corresponding questions to a sharepoint list. I'd like to only write back the answers that have changed. Below is my code for determining if a change has been made. However, it is always triggered when I write the questions to my table. Is there a way to make it so that the Changed Event is inactive until all of the questions have been loaded the first time?

public void gpSection2_2E_1_Changed(object sender, XmlEventArgs e)

{

// Get a reference to the form's XmlNamespaceManager object.

XmlNamespaceManager ns = this.NamespaceManager;

// See if values have been changed.

if (e.Operation == XmlOperation.ValueChange)

{

e.Site.SelectSingleNode("my:Updated2.1", ns).SetValue("true");

}
