Access Combobox Selecteditem Windows Forms C#

Question

I put the items inside the combobox as follows:

cmbSituacao.DisplayMember = "Text";
cmbSituacao.ValueMember = "Value";
cmbSituacao.Items.Add(new {Text = "TODOS", Value = "000000"});

foreach(var sit in recSituacao)
{
  cmbSituacao.Items.Add(new {Text = sit.DESCRICAO, Value = sit.ID_SITUACAO });
  cmbSituacao.SelectedIndex = 0;
}

But I can’t access the values, follow the code:

object ss = cmbSituacao.SelectedItem;
if (cmbSituacao.GetItemText(cmbSituacao.SelectedItem).Equals("TODOS"))
  filtro = filtro.And(s => s.ID_SITUACAO == cmbSituacao.SelectedValue.ToString());

Actually your code needs several improvements. First you should use the property DataSource of the component ComboBox to fill in the items so that you can use the component’s resources correctly. To do this, create a class ViewModel to the ComboBox:

public class ComboViewModel
{
    public string Text { get; set; }
    public string Value { get; set; }
}

This class will be your template so create a temporary list that will receive your items and then seven this list as the property DataSource of the component.

List<ComboViewModel> listaTemporaria = new List<ComboViewModel>()
{
    new ComboViewModel { Text = "TODOS", Value = "000000" }
};

listaTemporaria.AddRange(recSituacao.Select(sit => new ComboViewModel{  Text = sit.DESCRICAO, Value = sit.ID_SITUACAO }).ToList());

cmbSituacao.DataSource = listaTemporaria;
cmbSituacao.DisplayMember = "Text";
cmbSituacao.ValueMember = "Value";
cmbSituacao.SelectedIndex = 0;

Before this when accessing the selected value in Combobox use the code below:

ComboViewModel itemSelecionado = cmbSituacao.SelectedItem as ComboViewModel;

if (itemSelecionado != null && itemSelecionado.Text != "TODOS")
  filtro = filtro.And(s => s.ID_SITUACAO == itemSelecionado.Value);

Any questions let me know, I am without Visual Studio now and I did in the notebook, there may be some mistake.
