Hi,

I have placed an input button (by default disabled) and radeditor in my screen. I want to fire a command on click of the button when it got enabled. But the button throwing me a javascript error when it is disabled. The exception details are as follows,

Line :    5949
Error:    Sys.ArgumentException: Value must be a DOM element.
Parameter Name: element.


And it is observed that, when no editor is placed in the form and clicking the button is not throwing any exception.

Please give me some suggestions to resolve this problem.

Hello Sambasiva,

Please, open a support ticket and send a sample working project that demonstrates the problem. I want to examine your code and reproduce the problem. Once I am able to reproduce the problem I will try to provide a solution.

Looking forward to hearing from you,

Hi Sambasiva,

Thank you for the provided project in your support ticket.

I examined it and found that the problem is due to a well known bug in ASP.NET AJAX which appears only with disabled elements. It has nothing to do with RadEditor and can be reproduced with the following code:

<head runat="server">
    <title>Untitled Page</title>
    <script>
    function ExecuteCommand(cmd)
    {
         alert(1);
    }
    </script>
</head>
<body>
    <form id="form1" runat="server">
        <telerik:RadScriptManager ID="RadScriptManager1" runat="server"/>
       
        <input type="button" value="Bold" onclick="ExecuteCommand('Bold')"/>
        <input type="button" value="Italic" onclick="ExecuteCommand('Italic')" disabled/>
       
        <telerik:RadEditor ID="RadEditor1" runat="server" EditModes="Design">
        <Tools>
            <telerik:EditorToolGroup Tag="Bold"></telerik:EditorToolGroup>
        </Tools>
        <Content>
            Sample application
        </Content>
        </telerik:RadEditor>
    </form>
</body>
</html>

The problem is logged in ASP.NET AJAX bug tracking system and the guys from MS should fix it.

Hi Sambasiva,

As I wrote in my earlier reply this is an issue with the ASP.NET AJAX framework in general (when having disabled elements) which is confirmed in the following public forum post:

http://forums.asp.net/p/1151199/1918939.aspx

The bug should be resolved by Microsoft.
