I have a form with TextBox and ToolStrip. I'm handling the data upon leaving the control (through 'Leave' event handler).

When a button on the Toolbar clicked, the TextBox's Leave event is not triggerred.

How do I make sure the Leave event is triggered?

OR How can we find the last control had the focus?

I've found the answer to my real issue.

The issue is, the ToolStrip buttons doesn't cause 'VALIDATION'.

Resolution:

By invoking 'this.Validate()' (this refers the form) from ToolStrip's clicked event forces the validation for all the controls. Thus the data can be handled upon 'OnValidating' event.

Thx. & Good luck everybody.

How do you know that the TextBox "had" the focus? Or do you really want "MouseLeave" instead of "Leave"?

Thx for your response.

I'm expecting the 'Leave' event.

Situation:

Form have several Text Boxes fordata entry. The data is validated and updated upon 'Leave'. After the data modification in any of the TextBox,pressing a button(say Save button)on the toolbar is not triggering the 'Leave' event handler.

It seems the event handler is not attached to the event.. And the better way to validate the entry is to write the code in the Validating event not in the Leave event.
