Question

I am implementing a WinForms form in a C# project.
My form is a child of a MDI form.
My form contains a user control.
My user control contains some buttons including a validation button and a cancel one.

I want to implement the following logic :

• When my form is active and the user presses the enter key then I want the validation button clicked event to be fired automatically.
• When my form is active and the user presses the escape key then I want the cancel button clicked event to be fired automatically.

If my validation and my cancel buttons were not included in a user control then I would probably set the AcceptButton and CancelButton properties of my form.

Answer 1

Here is the code I have written in the Load event handler of my user control according to a tip given by Arthur in a comment to my first post :

// Get the container form.
form = this.FindForm();

// Simulate a click on the validation button
// when the ENTER key is pressed from the container form.
form.AcceptButton = this.cmdValider;

// Simulate a click on the cancel button
// when the ESC key is pressed from the container form.
form.CancelButton = this.cmdAnnulerEffacer;
