I have a ComboBox
that gets filled with items from my database. I'm trying to get the ID
of the item that is selected in the ComboBox
, but nothing I've tried seems to be working.
int id = cbbilar.SelectedIndex + 1;
This is how I have it right now, it's very inefficient and stops working if the first items in the database are removed
var cars = (from z in db.Bilar
select new { Value = z.Id, Names = z.Marke.Namn + " " + z.Namn }).ToList();
cbbilar.DataSource = cars;
cbbilar.DisplayMember = "Names";
cbbilar.ValueMember = "Value";
cbbilar.SelectedIndex = 0;
This is the code for my Combobox
. How do I make it fetch the ID
of the SelectedItem
?
You need to use SelectedValue
and int.TryParse
method. Like this:
int id;
bool result = int.TryParse(cbbilar.SelectedValue.ToString(), out id);
Here is what I got done:
comboBoxPickupLoc.DataSource = pickupLocationRepo.GetPickupLocations();
comboBoxPickupLoc.DisplayMember = "LocationName";
comboBoxPickupLoc.ValueMember = "Id";
comboBoxPickupLoc.SelectedIndex = -1;
and then you can get the Id value as shown below
object value = comboBoxPickupLoc.SelectedValue;
MessageBox.Show(value.ToString());
Thanks.
