How to disable the OnEvent attribute server-side in Ext.Net?

Question

ExtJS/Sencha

My aspx has a button:

<ext:Button runat="server" ID="SaveButton"
                    Text="Save"
                    Icon="PageSave"
                    meta:resourcekey="SaveButton">
                    <DirectEvents>
                        <Click OnEvent="SaveData">
                            <EventMask ShowMask="True"></EventMask>
                        </Click>
                    </DirectEvents>
                </ext:Button>

Due to the architecture of the application, I do not have the right to edit aspx. How can I write an OnEvent cancellation in C# or JS? That is, so that the specified SaveData method does not work?

Answer 1

The answer, it turns out, was simple:
SaveButton.DirectEvents.Click.Event -= SaveData;
