Question

Is there any way to turn the damned error provider off when i try to close the form using the windows close button(X). It fires the validation and the user has to fill all the fields before he can close the form..this will be a usability issue because many tend to close the form using the (X) button.

i have placed a button for cancel with causes validation to false and it also fires a validation.

i found someone saying that if you use Form.Close() function validations are run…
how can i get past this annoying feature.

i have a MDI sturucture and show the form using

 CreateExam.MdiParent = Me
        CreateExam.Show()

on the mdi parent’s menuitem click

and have this as set validation

Private Sub TextBox1_Validating(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles TextBox1.Validating
        If String.IsNullOrEmpty(TextBox1.Text) Then
            Err.SetError(TextBox1, "required")
            e.Cancel = True
        End If
        If TextBox1.Text.Contains("'") Then
            Err.SetError(TextBox1, "Invalid Char")
            e.Cancel = True
        End If
    End Sub

Any help is much appreciated.
googling only showed results where users were having problem using a command button as close button and that too is causing problem in my case

Answer 1

The ValidateChildren() method prevents the form from closing. Paste this code in your form to fix that:

protected override void OnFormClosing(FormClosingEventArgs e) {
  e.Cancel = false;
}
