Thank you for writing.
According to the provided information, I am not sure how exactly you set up your application. That is why I have prepared a sample project following the demonstrated approach in the following help article: https://docs.telerik.com/devtools/winforms/menus/menu/working-with-radmenu-items/nesting-controls-in-menu-items
Indeed, the Validating
event is not fired for the hosted textbox. I have logged this for further investigation because RadMenu
is a non-selectable control and hosting focusable elements is a very specific case. You can track its progress, subscribe for status changes and add your comments on the following link - feedback item
I have also updated your Telerik points.
Currently, I can suggest you using the LostFocus
event which seems to be fired on my end when another control is focused. There, you can simulate the validation.
I hope this information helps. Should you have further questions I would be glad to help.
