Currently, when you instantiate the Articles module and set it to filter by category, it ORs together the categories selected. I would like to see a switch in the settings to allow this to be selectable AND/OR so that you can use categories for different purposes.

In recent versions, we added the ability to specify MustHaveAllCategories (i.e. And) vs. MustHaveOne (i.e. Or) on the backend. Currently this isn't used by any of the released pieces of the interface. We hope to release a Category Tab bar that makes use of the functionality in the next version.

Cool David! Is there anyway to accelerate this development? I could really use this like -- right now ;-)

Conversely -- since I have the source to the categories module -- I could probably figure out how to do it myself... eh?

The functionality is already there. It's really just a matter of styling it all nicely. The MustHaveOneCategory and MustHaveAllCategories is already released. We've built the Category Tab bar a couple different ways for different clients but want to tweak it some before releasing it. But, if you include the Categories module on the Articles page and then click on a category, it will append the category to the QueryString and that will filter the Articles module by that category as a MustHaveAll. So, you could either modify the display listing of Categories or you could copy the rendered code generated by the Categories module and then tweak it to meet your needs until we release the Category Tab Bar.

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?

you never really stated what you were trying to do, but that should cause the module to only show articles that match all of the specified categories.

David: Is this the only change required to get the AND vs OR behavior? I am not seeing any change in behavior...

OK - Never-mind my last post. I screwed up the fiilename. I've fixed that, and now I am getting this error when I try to logon to the portal: Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.
