Using values in combox in windows application

I'm writing a windows application in VB.NET. I'm using a combobox to display text, but I want to store a numeric value with each line. When an item is selected, I want to be able to retrieve the numeric value. I know how to do this in a web application but it appears to be totally different in windows apps. This was fairly easy to do in VB6 but I can't figure out how to do it in VB.NET. Would appreciate any help.

Hi stephenkobrien,

Is your combobox bound to a source?

You normally bind the DisplayMember (value that the user will see) and the ValueMember (your value accessible using SelectedValue).

Cheers!

Dim dsDataset As New DataSet
Dim drNewRow As DataRow

dsDataset.Tables.Add()
dsDataset.Tables(0).Columns.Add("TheDisplayText")
dsDataset.Tables(0).Columns.Add("TheValue")
drNewRow = dsDataset.Tables(0).NewRow

drNewRow.Item("TheDisplayText") = "Item #1"
drNewRow.Item("TheValue") = 1
dsDataset.Tables(0).Rows.Add(drNewRow)

cboComboBox.DisplayMember = "TheDisplayText"
cboComboBox.ValueMember = "TheValue"
cboComboBox.DataSource = dsDataset.Tables(0)

Actually, I found the answer at msdn. You need to create a class that exposes public properties that are assigned to the DisplayMember and ValueMember properties of the control. See the link: http://msdn2.microsoft.com/en-us/library/system.windows.forms.listcontrol.valuemember.aspx
