I would like to ask the user to save the text before leaving the page. I use the onbeforeunload event for this. But when the user clicks my savebutton in the toolbar,  a beforeunload event is fired before the postback is fired. Does anyone has the solution for this problem?   Thanks, Arno

Can you try this example?   http://richtextbox.com/userexample/ajax-support.aspx    

Hi,   We have found the reason , and will fix this issues in 2 days.   Regards, Terry

Have you guys ever run into the issue with the click for live support graphic sometimes disappears on a partial postback?

 Ps. Trying to do this without a postback.

It appears that setting the .GetItemsTable().Visible = False causes the .Items collection to be empty on postback. Is this the correct behaviour?  

Can you show the source code? Your example seems to require a postback, can't it be done client-side with a basic RequiredFieldValidator control?

Hi,   What's your code ??   in script , you can get the file guid list just from uploader1.value .   If you want to do a AJAX postback , you must add the values of all form elements into the post data.   Regards, Terry

Still no postback with the change. Thanks.

In IE8 the javascript method "CuteWebUI_AjaxUploader_OnInitialize()" is never called. So I suppose the Uploader is never initialized, which would explain why the button performs a postback instead of the desired behaviour.  Any Ideas why Uploader won't initialize?
