QuestionCombobox Text Pin

Hi, Folks.

I have a problem and expect you can help me. I use C# in Visual Studio 2019. I have a combobox which I populated with a table data. I used a Datasource to do this. When the user selects a value I need a variable to receive the string value of the combobox.
My snippet is as folows:
private void Cb_Campo_SelectionChangeCommitted(object sender, EventArgs e)
{
    if (_Modo != 0)
    {
        Cb_Campo.DisplayMember = CampoTexto;
        Cb_Campo.ValueMember = CampoChave;
        ValorChave = int.Parse(Cb_Campo.SelectedValue.ToString());
        ValorTexto = Cb_Campo.SelectedItem.ToString();
    }
}

Before selection, the combobox has "Select" as a text. Tha variable ValorChave is receiving the correct value, but the variable ValorTexto, with the code above, receives "System.Data.DataRowView".
If I change that line for
ValorTexto = Cb_Campo.Text

The result is "Select", which is the initial text.
Obviously, what I need is the corresponding value to the SelectedValue.
Can anyone help me solve this?
Thanks a lot.
