Many thanks, I realise I need the continuity of a Dataset. I have not
Datasets for a while, could you point me to a good article?

I am filling a ListBox from a stored proc and a SQLDataReader which works fine.

Private pCateg As SqlCommand

pCateg.CommandType = Data.CommandType.StoredProcedure
pDR = pCateg.ExecuteReader
ListBox1.DataSource = pDR
ListBox1.DataTextField = "Category"
ListBox1.DataValueField = "Category"
ListBox1.Databind

I am trying to use the Value/Text of the Selected Item but am failing to get
that value which is coming back as a Null:
ListBox1. SelectedValue

How should I test that an Item has been selected and then get the value for
further use?
With thanks

You are using the wrong type of object as a DataSource (It should
throw an exception).

Recommend a DataSet (one created in the App_Code folder as an XSD
file). Create a TableAdapter that uses the "pLodge" stored procedure
as its select command.
