I have a table that contains rows, obviously. Each of the rows in my table represents a different report. I would like to use role based security to manage which user has access to which report. What I'll do is fill a listview and give them the ability to select and print multiple reports at once. When I fill the listview, I'll only want it to fill it with rows(reports) that this user has access to.

I hope this makes sense.

Yes, you can use the type editor.  It  is just a class within the MicroFOur StrataFrame Extensibility.DLL.  However, this can be used as design-time only.

The UI Type Editor class is called SecurityKeyTypeEditor.  You can also call the form directly and provide the parms which would be the SecurityKeyTypeEditorDialog.
