WinForms combobox with multiple columns (C#)?

Question

I am using currently the following code to populate a combobox:

combobox.DataSource = datatable;
combobox.DisplayMember = \"Auftragsnummer\";
combobox.ValueM         


        

Answer 1

You can add to your dataset a dummy column (Description) and use that as DisplayMember in the combo box databinding.

SELECT Users.*, Surname+' '+Name+' - '+UserRole AS Description FROM Users

ComboBox.DataBindings.Add(new Binding("SelectedValue", bs, "ID"));
ComboBox.DataSource = ds.Tables["Users"];
ComboBox.DisplayMember = "Description";
ComboBox.ValueMember = "ID";

Simple and works.
