Question

All,

I have a simple windows form with a combobox and a ‘OK’ button. After clicking the ‘OK’ button, I want to retrieve the selected combobox value.

The GetUserForm has 2 controls:
combobox named cmbUser, with a list of 2 values
button named btnOK

Nothing has been done to the GetUserForm class itself. The class contains:

public partial class GetUserForm : Form
{
    public STAMP_GetUser()
    {
        InitializeComponent();
    }
}

GetUserForm f = new GetUserForm();
f.ShowDialog();
// not sure how to access the combobox selected value?

Do I need to initialize something in the class? Or can I access the controls on the form using the ‘f’ variable above?

Answer 1

You need to expose the value of the ComboBox as a public property. Something like that :

public string SelectedUserName
{
    get { return cmbUser.Text; }
}

Or perhaps :

public int SelectedUserId
{
    get { return  (int)cmbUser.SelectedValue; }
}
