Just add a line to filter out the Delete.

Thanks for the reply, Patrick. It does seem very strange to me that both of those events would raise the OnAfterChange event though. Do you know of a better way to perform the action that I'm attempting?

I have noticed similar things in the past with the events being raised. Seems a little weird. This is an event that is raised off the XML DOM? If so, do you know where I can go read up on this topic? W3C?

Checkboxes receive an e.Operation of Delete and then Insert.

Why is OnAfterChange firing twice?

DC Ross — Fri, 23 Sep 2005 17:44:22 GMT

I have some checkboxes in a form that can perform a couple of functions depending on the value of a textbox. Things work correctly, except that OnAfterChange is firing twice, and I have no idea why...

Here's a simplified snippet:

[InfoPathEventHandler(MatchPath="/my:Form/my:Checkbox", EventType=InfoPathEventType.OnAfterChange)]
public void Checkbox_OnAfterChange(DataDOMEvent e)
{
string myTextboxText = thisXDocument.DOM.selectSingleNode("/my:Textbox").text;
if(myTextboxText != "")
thisXDocument.UI.Alert("Please enter something in the textbox");
}

Any help you can provide is greatly appreciated.

Thanks,
