Listbox selectedvalue is nothing 1

[xenology]

I have four listbox controls on my page. Each is bound to a dataset (listbox.datasource to the dataset, listbox.datatextfield to dataset.column, listbox.datavaluefield to dataset.keycolumn). In form load I set the parameter to the data adapter, fill the dataset, and listbox.databind. When running the page shows and the listboxes display their data. When you click on a row in the listbox and click the 'Add' button, I am trying to get the one they selected and insert that info into the table. However, listbox.selectedvalue = "" and listbox.selecteditem = Nothing even though it is showing as highlighted on the page.
Any Ideas?

Try

ListBox1.SelectedItem.Value

enabledviewstate = true must be on for the page if you're getting the value on a button click or some other form of postback.

checkai,

I disagree actually! Using ListBox1.SelectedItem.Value will still return the selected value if the enabledviewstate is set to False.

It was actually still the code of listbox.selectedvalue.

my problem was in Form Load. It seems the page was refreshing before the click event of the button. To correct the problem, I encased the data adapter / dataset / listbox binding with an IF NOT thisPage.PostBack THEN statement. At that point, selected value started returning the info.

thanks for the thoughts though!~
