We have the latest update for Ajax installed today and have found an issue with the RadSpell control. If you type a value of 'tha' into a textbox/text area control that spell check will target, you will get an error 'Uncaught SyntaxError: Unterminated string in JSON' error in the console. This is able to replicated within the demo page of the Spell control.

https://demos.telerik.com/aspnet-ajax/spell/examples/overview/defaultcs.aspx?_gl=1*19wdrka*_gcl_au*NTA5NTg2MDEuMTc0MDYwNDU5NQ..*_ga*MjA4NzU2NTg4MC4xNzQwNjA0NTkx*_ga_9JSNBCSF54*MTc0MDYwNDU5MS4xLjEuMTc0MDYwNjI5Mi42MC4wLjA.

Remove the text in the first textbox in this page and replace it with 'tha' and in the console you will see the error shoot off.

The error (Uncaught TypeError: Cannot read property 'mouseup' of undefined or SCRIPT5007: Unable to get value of the property 'mouseup': object is null or undefined ) manifests in Chrome and IE9 only and only if you have a debugger on, otherwise the page simply disposes without issues.

Wave Structure/Order is giving an error for RadSpell Control at "Not in Dictionary" label and Suggestions label. Hence our 508 testing is not passed. 

Please find the attachment for more details.

Missing <h1> of Spell Check at the top of the dialog.

Not in Dictionary and Suggestions should not be headings they should be form labels.


Thanks

FIX Setting Enalbled="false" for RadSpell does not have effect on the control.

The disabled="disabled" attribute is applied to the main wrapper of the control instead of to the button.

The following script is a possible workaround:
	<asp:TextBox ID="Textbox1" runat="server" />
	<telerik:RadSpell ID="RadSpell1" ControlToCheck="Textbox1" Enabled="false" OnClientLoad="OnClientLoad"
		runat="server" />
	<script type="text/javascript">
		function OnClientLoad(sender, args)
		{
			if ($telerik.$(sender.get_element()).attr("disabled") == "disabled")
			{
				$telerik.$("input[type='button']", sender.get_element()).attr("disabled", "disabled");
			}
		}
	</script>

It will work as-is for a regular push button. If the ButtonType is changed the script needs to change to get the appropriate element (e.g. anchor for the LinkButton).
