Potential bug with UpdatePanel and firefox

[Michael Onstad]

I have a button inside an UpdatePanel with an OnClick Event set that updates a DataList.

If I use the RadFormDecorator to style my button, the Click event doesn't seem to work under FireFox. As soon as I take the RadFormDecorator out, my button works as expected under firefox.

Hi Michael,

Thank you for bringing this issue to our attention. We investigated it and here are our findings:

1. The problem does not exist if UpdatePanel is not used.
2. The setup works under IE in all cases.
3. Ultimately the reason for the problem is in the Firefox implementation. It can be reproduced if no RadControls are used as well.

Here is a sample setup that reproduces the problem without RadFormDecorator - it actually represents how the RadFormDecorator works. When you click a "decorated" button, RadFormDecorator finds the corresponding real button and call its click() method:

<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="panel1" runat="server">
    <ContentTemplate>
        <script type="text/javascript">
            function submitForm()
            {
                var input = $get("<%=Button1.ClientID %>");
                input.click();
            }
        </script>
        <button onclick="submitForm();return false;">
            Click to submit</button>
        <asp:Button ID="Button1" runat="server" Text="test" OnClick="Button1_Click" /><asp:Label
            ID="lbl1" runat="server"></asp:Label>
    </ContentTemplate>
</asp:UpdatePanel>

The good news is that there is an easy solution for this case - you only need to set the button's UseSubmitBehavior property to false (it is true by default). Then the button will be rendered as <input type="button" .. element and everything will work as expected.

Is this the only solution, because UseSubmitBehaviour can't be set in skin file so you have to change manually every button and be careful with new one.

I am having an identical issue but i'm using an imagebutton to switch a panel on which contains 5 radeditors which are not displaying correctly. If i cancel the panel then switch it on again the radeditors display properly.

THe UseSubmitBehavior solution is not working for me...any other way to solve this.  Again this is only in Firefox and Chrome.

Stephen
