Hi Vladimir Abramchuk,
Thank you for contacting us.
In regards to your question, the correct approach is to override the OnMouseDown
) method and put your logic there. Please consider the following code snippet:
MyApplicationMenu : RadApplicationMenu
(e.Button == System.Windows.Forms.MouseButtons.Left)
You can override the OnKeyDown method for the cases concerning keyboard navigation.
Please note that you need to override the ThemeClassName in the custom application menu implementation as well. For additional information, please refer to this article
I hope you find this information helpful. Should you need additional assistance, do not hesitate to contact us.
All the best,
the Telerik team
