    We have PDF forms that are specific for each State.  Instead of creating a page for each state, I'd like to pass the state via querystring and then select the appropriate document libraries based on that querystring.  There will be two libraries to select documents from.  One has generic PDFs that are available for all states.  These PDFs are in a separate library.  And the second library will be state specific.  What would be the easiest way to accomplish this?

    Hello Bart Welch,

    By default the document files are shown by download list control. After you append the QueryString to the url with the proper data, you have to create a custom control that inherits from DownloadList. Inside your custom class override CreateChildControls and before calling the base apply ContentFilter

    ContentFilterBuilder filterBuilder = new ContentFilterBuilder(this);
     filterBuilder.AddFilter(new ContentFilterStatement("param", value, ContentFilter.Condition.Equal, ContentFilter.JoinType.And));

    by doing so you will filter the content list and your users should see the proper data.

    Another option is overriding CreateDataSource() method where you could return the items only for a certain library.

    var m = new ContentManager("Libraries");
    // parent ID is the library ID
    IList l = m.GetContent(0, 0, string.Empty, parentID);

    Best wishes,
