Tim,

At the beginning of this particular form's code, at the top of the class, I've included the following lines:

Public oReportCat as New Bus.ReportCatalog
Public dtReportCat as DataTable = oReportCat.GetAllData()
Public dvReportCat as DataView = me.dtReportCat.DefaultView

...so, yes, dtReportCat is a DataTable

The workaround in the form load method didn't intentionally avoid using the mmListBox properties. We're pretty new to MM.Net here and I apparently grabbed the first thing out of IntelliSense that made some sense. It also worked, by the way.

Having received your last note, I went back and tried the following code in the form's load method:
me.dtReportCat = oReportCat.GetAllData()
me.lstReportCat.BindingSource = me.dvReportCat
me.lstReportCat.BindingSourceDisplayMember = "strReportName"
me.lstReportCat.BindingSourceValueMember = "strReportFile"
me.lstReportCat.Enabled = True
me.optAllReports.Select()

This gives me an error at the line where the binding source is assigned because dvReportCat is a view and can't be converted to a string, which the bindingSource property expects. Does the same thing if I use dtReportCat.

If I remove the BindingSource line, I don't get an immediate error, but every line in the list box shows the same thing, specifically:
System.Data.DataRowView

I don't know what we're doing wrong. I be happy if we've just been stupid and have missed something obvious.

Any further clues?

Thanks,
Frank
