BUT, as I give the ability to the user to change the issues whenever they want, this doesn't work. Private void btnSave_Click(object sender, EventArgs e)ĮmployeePresenter.addEmployee(txtFirstname.Text, txtLastname.Text, txtUsername.Text, txtPassword.Text) The error provider works correctly and my user can edit whenever he wants. If (!InputChecks.IsFilledIn(txtFirstname.Text))ĮrrorProvider1.SetError(txtFirstname, "Firstname needs to be filled in!") ĮrrorProvider1.SetError(txtFirstname, "") So, now the code: private void txtFirstname_Leave(object sender, EventArgs e) This because otherwise I noticed you cannot go to another field, until you changed your error. So when there are still errors, the "save" button will keep greyed out or "disabled".īecause I don't want to block my user when he is making an error, and I want him to be able to make the changes whenever he wants im using the event "leave" or on focus lost. Once on the textfields directly, so the user sees that he has made some errors, and once on the button itself. Now I want to have a "double" validation.
