Listbox Display Using BindingSource?

I have a SQL table that contains 2 columns - report names and report category. In my application, I have one listbox that displays these report names. I have several categories for the different reports I have. Is there a way for me to display reports belonging to a particular category in one listbox and then have another listbox for another category? This way, depending on user login, I can selectively disable certain reports from certain users. I was hoping that this can be done during form load and not having to click a button to do any BindingSource.Filter method(). I have command buttons that let me search for a particular report based on user input of either the report name or category using the BindingSource.Filter method(). For my Listbox, I have the DataSource & DisplayMember properties set to Report_NamesBindingSource and ReportName. For one of my tests, I took out these two properties and wrote the ff code -

lstBxReportName.DataSource = "Report_NamesBindingSource"
lstBxReportName.Items.Add(Me.Report_NamesBindingSource.Filter = "ReportCategory = Cath")
lstBxReportName.DisplayMember = "ReportName"

hoping to set these properties programmatically and hopefully filter the dataset based on category but I get an error msg on the first line of code. -[QUOTE]Complex DataBinding accepts as a data source either an IList or an IListSource.[/QUOTE]Obviously, my code is wrong. When I comment out the first line and run it in debug, there is nothing in BindingSource.Filter when I hover my mouse pointer over the second line. So my listbox is empty when I run the program.The filter code below works fine for one listbox but I'd like to have different listboxes for report categories I have.- Me.Report_NamesBindingSource.Filter = "ReportCategory = 'Cath'"But how can I assign this type of filter to a particular listbox.
