errorprovider won't let me exit the form until I clear the error

Question

Why is it when I first come to my window which is a form with a user control and combo box set to blank. I can click Cancel without any problem and window closes. However, if I touch the combo box and then leave it blank and I try to click Cancel the cancel event doesn't fire?

All you actually need is

 e.Cancel = False;

in your FormClosing event.

I had to use container.AutoValidate = .EnableAllowFocusChange

I had the same issues, but then I solved it by

Setting the CausesValidation property of the button to False.
Re-setting all the controls on the form.

Closing the Form.

while (Controls.Count > 0)
      {
          Controls[0].Dispose();
      }
      this.Close();

I added this code to the Button_Click() event as well as the From_Closing event. Regards, Kshitij Thube

Rod's answer leads to the solution. If the forms (container of the error-provider) AutoValidate-property is set to EnableAllowFoucsChange, button events are handled and in the Click-Event now it is possible to check if the form has invalid children:

Private Sub Button2_Click(sender As System.Object, e As System.EventArgs) Handles Button2.Click
    If Not ValidateChildren() Then Exit Sub
End sub
