So... in the code below (from ArticleListBase.ascx.vb)...
Protected Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Try
'TODO: 4.1- Need option to display username or full name or displayed name for author (This can be done with template change)
'TODO: 4.1- Search results should include image thumbnail
'TODO: 4.1- Get DNN Export and Import functionality working
If rptArticles Is Nothing And lstArticles Is Nothing Then
Exit Sub
End If
FilterByCategory = Settings("FilterByCategory") = "True"
If FilterByCategory Then
MustHaveOneCategoryList = Settings("CategoryID")
End If
all that I need to do is change
MustHaveOneCategoryList = Settings("CategoryID")
to
MustHaveAllCategoryList = Settings("CategoryID")
and I am done?
