.net - Winforms Form Constructor vs Load event

Question

When a form loads, the code needs to do things like setup datagrids, comboboxes, set the title, etc. I've tended to always use the load event rather than the new (constructor). Are there any guidelines for which one is best for which activities?

Answer 1

A call to InitializeComponent is automatically inserted in the constructor of your form/page. InitializeComponent is the auto-generated method that

• creates the various UI elements on your winform / XAML page
• initializes their properties with the values stored in the resource file

So anything related to UI arrangement/modifications should go after this call. When you do this in an override of Form.OnLoad , you're assured that the UI is ready to go (InitializeComponent has been called)... so I'd vote for sticking to OnLoad for UI.
Creating non-UI members, constructor would be the place I'd first look at.
