HI friends,
I'm using Ext.net 2.0. Then I found a issue as the title. I tried search answer but get none. Below is my code and the enviroment.

First of all, Login form work properly when clicking the LOGIN button.

JS Code:
    <script type="text/javascript">
        var EnterPressHandler = function (field, e) {
            if (e.getKey() == Ext.EventObject.ENTER) {
                Ext.getCmp("btnLogin").fireEvent("click", Ext.getCmp("btnLogin"));
            }
        }
    </script>
aspx code:
<ext:TextField EnableKeyEvents="true" runat="server" FieldLabel="Password" AllowBlank="false" BlankText="Required" ID="txtPassword" InputType="Password">
                            <Listeners>
                                <SpecialKey Fn="EnterPressHandler"></SpecialKey>
                            </Listeners>
                        </ext:TextField>
When press Enter in the password TextField, it do fire a 'click' event to the btnLogin button, I can see the MaskMsg, but has different behavior as Directly Clicking the btnLogin Button which will login correctly. I don't know the reason. Pls. help me. Thank you.
