Hey,
I am using a FormView and when I want to update something I have edited, I always get this error:
No value given for one or more
required parameters.
I use a SQLDataSource in combination with a FormView
This is the code of my SQLDataSource
<asp:SqlDataSource ID="sqldsLokaalPrinters" runat="server"
ConnectionString="<%$ ConnectionStrings:connRand2 %>"
DeleteCommand="DELETE FROM [tblComputers] WHERE (([tblArtveldenr] = ?) OR ([tblArtveldenr] IS NULL AND ? IS NULL))"
