How to "call" and event

Question

I have a form containing a textbox and a button. The textbox has code in the Validating and Validated events. The validation code is only called if the textbox gains focus so that the Leave event fires. I want the text box validation to fire if the button is clicked and the textbox never had focus. Is there a way to do this? Thanks

Call YOUR event handler not system handler: myTextBox.myTextBox_Validating(this...); But You can call system handler after creating Your own control inherited from TextBox. Next create a new method calling OnValidating() etc. methods in it: public class VTextBox: TextBox { public void UnconditionalValidating() { System.ComponentModel.CancelEventArgs e=new System.ComponentModel.CancelEventArgs(...); this.OnValidating(e); ... } }

How do I find the event handler for a system event? Do you have a code sample I could use as a guide?

Call Your event handler not event.

There's probably a direct way of doing it but I don't know it offhand. A quick and dirty way would be to set the focus to the textbox in the button click event and then set the focus right back to the button. It might do the trick.
