I am using the following code as an example. Once the user selects an item
from the combobox (e.g., "Martin"), how can I access the value of that item
(e.g., "1")?

Thank you,

DD

Dim dtAdjuster as new DataTable
dtAdjuster.Columns.add("Names")
dtAdjuster.Columns.add("Keys")

dtAdjuster.loaddatarow(new object() {"Martin", "1"},true)
dtAdjuster.loaddatarow(new object() {"Cor","2"},true)

'This can all in probably hundred other ways, this is the way I do it.

Combobox1.datasource = dt
Combobox1.displaymember = "Names"
Combobox1.Valuemember = "Keys"

Combobox1.SelectedValue.ToString

I tried that, it is returning "System.Data.DataRowView" as the value of the
item. What is wrong? Any idea?
