Selecting item in databound combobox

Question

I believe this question is kinda new-bie, but I can't solve it in correct way.

Brief description:

1. I have an inherited from ComboBox class that does some data bindings in constructor:

var mdl = new Model();

    ValueMember = "id";
    DisplayMember = "unit";
    DataSource = mdl.getUnits();

All good here. The combobox is filled by required data.

1. Then I have another form with a function editIngridient. The function is following;

public bool editIngridient(int id)
    {
    currentId = id;

    var row = mdl.getIngridient(id);

    txtIngridient.Text = (string)row["ingridient"];
    cmbUnit.ID = (int)row["unitId"];
    numNotifyQty.Value = (int) row["notifyQty"];

    ShowDialog();

    return true;
    }

1. Now, when the form popups, textbox and number box filled by needed values, while combobox is filled by first value.

2. If I will run the combobox data bind function as the first line inside editIngridient function - all works good.

Please point me to my stupidity.

Thanks a lot!

YOu didnt say what is your dataSource, but I assume thats DataTable, so you can do it:

DataRowView rowData = comboBox1.SelectedItem as DataRowView;
int id = Convert.ToInt32(rowData["id"]);
string name = rowData["unit"].ToString();
