Thread: Programmatically Select Item in ListBox or DropDownList

A common question that I see posted all over the place is "How can I programmatically select an item in my dropdownlist or listbox based off a certain value?"

It's actually quite simple and here's how to do it:

Code:

For Each Item As ListItem In MyListBox.Items
    If Item.Value = "4" Then
        Item.Selected = True
    End If
Next

This is useful when, for example, you're reading values from a DataReader and what to pre-select an option based off of that value.
