Hi Loren,

There's still no news on ASPNET-176. I will give you an update if I hear any news regarding this. For a workaround, you could run the following javascript on WebScheduler Client side event:

function WebScheduler1_OnInitialize(controlId) {	if (window.Event && !window.Event.prototype.preventDefault)
		Event.prototype.preventDefault = function () {
			this.returnValue = false;
		}
	if (window.MSEventObj && !window.MSEventObj.prototype.preventDefault) {
		window.MSEventObj.prototype.preventDefault = function () {
			this.returnValue = false;
		}
	}
}

Please note that this workaround won't work on IE 7.

Best Regards,
Leo

Hi Loren Devine,

Sorry for my late response. I have submit this issue under "ASPNET-175" For IE11 on Edge Compatibility View, and "ASPNET-176" Drag to resize issue. I will keep you update regarding this issue.

In compatible mode for IE 11, IE 10, IE 9, IE 8, and IE 7, the drag to resize time duration throws a javacript error "Object doesn't support property or method 'preventDefault'". This prevents the resize from saving to the database which is causing issues for our users.

Is there a timeline on when support will be added for compatible mode for IE11 or Edge?

Hi Loren,

Compatible mode for IE11 or Edge still not supported currently. For your information, Compatible mode for Edge or IE11 have some compatibility changes to several of it's api features. In this case, the 'attachEvent' issue that you are facing was caused by attachEvent API feature was removed.

If I click and drag to create an appointment in IE11 with X-UA-Compatible Set to Edge, I will receive an "Object doesn't support property or method 'attachEvent'" javascript error. This will also happen if I click on the event and then click Edit as well.

If I perform these sames actions in IE11 or IE11 with X-UA-Compatible Set to 10, I don't receive any errors and everything works correctly.

What is X-UA-Compatible? https://www.modern.ie/en-us/performance/how-to-use-x-ua-compatible

Due to a previous issue, we forced our IE 11 users to add our site to their Compatibility View Settings and we added the meta tag described in the above article to force the user into IE9 mode. The issue is now resolved, and I'm looking to force our users into Edge mode. This is when I discovered the 'attachEvent' issue described above with the WebScheduler.
