Hi Cooper,

Thank you for writing.

You can override the ValidateInput method of the EditAppointmentDialog an validate your data in there. This method is called once the OK button is clicked and if it returns false, the dialog will not be closed. Here is a small sample:

protected override bool ValidateInput()
{
    bool result = base.ValidateInput();

    if (txtEmail.Text == string.Empty)
    {
        this.errorProvider.SetError(this.txtEmail, "Emails field cannot be empty");
        return false;
    }
    return result;
}

I hope that you find this information useful.

Thanks, it solved my problem.  

I have the same question with the delete button.

Hi Cooper,

There is a method for the DeleteButton as well. It is called OnDeleteButtonClicked. Here is what is does:

protected virtual void OnDeleteButtonClicked()
{
    this.DeleteEvent();
    this.DialogResult = DialogResult.Abort;
    this.Close();
}

I hope this helps.
