I have a problem which can be reproduced on the radeditor demo http://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx in Internet Explorer 11. I have tried in Chrome and the problem does not exists there.
The problem is, that when you select an image, then the properties tab and then click on other images, the properties tab width and height aren't being updated.
1. Open the Image Manager in the radeditor
2. Click on a random image.
3. Click on the "Properties" tab.
4. Click on another random image.
The result is that the Width and Height textboxes are blank.
I've tried taking a look at the usercontrol "SetImageProperties.ascx" and it seems that the variable originalImage in function "loadImageProperties" looses the height and width. I suspect that it's using the preview image from the Image Manager which is hidden when the property tab is selected. Do you know if there's a work around for this?
