Windows Forms Combo Box Text doesn't update when I manually change the text in the SelectedValu-CodePudding

I have the following code

private void cbAddTicketItem_SelectedValueChanged(object sender, EventArgs e)
{
     string[] arr = cbAddTicketItem.Text.Split(' ');
     cbAddTicketItem.Text = arr[0];
}

cbAddTicketItem is the combo box where the user is selecting from a list of items. The text of each item includes a description. I want to get rid of the description and just keep the value. Debugging shows that cbAddTicketItem.Text has the correct value but the text doesn't change on the form.

I think the issue is that either winforms is not firing the textChanged event, or it is overwriting it after my coded event runs.

You're making life rather hard work. It's easier if you do something like this:

var dt - new DataTable();
dt.Columns.Add("Disp");
dt.Columns.Add("Val");
dt.Rows.Add("Mark","1");
dt.Rows.Add("Luke","2");
dt.Rows.Add("John","3");

someCombo.DisplayMember = "Disp";
someCombo.ValueMember = "Val";
someCombo.DataSource = dt;

And then in some button click, let's say:

MessageBox.Show((string)someCombo.SelectedValue); //shows 2 if Luke is selected, etc
