面板自动滚动

Question

I have an UserControl and inside it I have some controls and one of these controls is a CheckBox . This CheckBox performs a CheckedChanged action that calls a method and this method sets some of the controls of the Panel to Enabled or Visible .

When I click to check the CheckBox the Panel where all these controls are inserted scrolls down automatically like the images below.

How could I stop the Panel scrolling down after checking the CheckBox ?

Inicial position

Position after checking the CheckBox

The code is below

The CheckBox Action

private void usuarioMedicoCheckBox_CheckedChanged(object sender, EventArgs e)
        {
            if(usuarioMedicoCheckBox.Checked)
            {
                carregarMedicos();
            } else
            {
                medicos = null;
            }

            usuarioMedicoComboBox.Enabled = usuarioMedicoCheckBox.Checked;
            cadastrarMedicoButton.Enabled = usuarioMedicoCheckBox.Checked;
        }

Method carregarMedico

            ParseQuery<Classes.Medico> query = new ParseQuery<Classes.Medico>();

            query.OrderBy("nomeCompleto").FindAsync().ContinueWith(resultado => {
                if (resultado.IsCompleted && !resultado.IsFaulted)
                {
                    medicos = resultado.Result.ToList();

                    atualizarMedicosComboBoxDelegate atualizarMedicosComboBoxD = new atualizarMedicosComboBoxDelegate(atualizarMedicosComboBox);
                    this.Invoke(atualizarMedicosComboBoxD, new object[] { });
                } else
                {
                    MessageBox.Show("Houve um erro ao buscar os médicos", "Erro", MessageBoxButtons.OK, MessageBoxIcon.Error);
                }

                processandoDadosDelegate processandoDadosD = new processandoDadosDelegate(processandoDados);
                this.Invoke(processandoDadosD, new object[] { false });

                {

Answer 1

Changing visible property of the button at the bottom of the panel, set the focus on that item. Try just to enable/disable that button instead.
