combobox getting value of selected value, winforms

Question

I have combobox cmbBoxA which is populated like this

private void FillComboBox() { foreach (var a in Helpers.Helper.GetData()) { cmbBoxA.Items.Add(a); } }

GetData has this code

public static List<VATMode> GetData() { List<VATMode> vatModes = Enum.GetValues(typeof(VATMode)). Cast<VATMode>().ToList(); return vatModes; }

Now I'm trying to fetch selected combobox item is with

int sel = Convert.ToInt16(cmbBoxA.SelectedValue);

but It's always 0?

update: enum is

public enum VATMode { A = 1, B = 2, C = 3 };

The Enum

public enum Status { Active = 0, Canceled = 3 };

Setting the drop down values from it

cbStatus.DataSource = Enum.GetValues(typeof(Status));

Getting the enum from the selected item

Status status; Enum.TryParse<Status>(cbStatus.SelectedValue.ToString(), out status);

I hope it will help you.. :)

ComboBox.SelectedValue is used when your ComboBox is databound and yours is not.

Change your code like this:

private void FillComboBox() { cmbBoxA.DataSource = Helpers.Helper.GetData(); }

and to get value back:

VATMode value; Enum.TryParse<VATMode>(cbStatus.SelectedValue.ToString(), out value);

and then you can cast it to int
