About

The GetFiltersData command is passed through rs.aspx via an AjaxRequest. This returns JSON formatted data related to the filters included in the reportSet. It can be used to identify and display filter information on the web page.

Here is the AJAX call to use:

AjaxRequest('./rs.aspx', 'wscmd=getfiltersdata', GotFiltersData, null, 'getfiltersdata');

Here is the hierarchy of the object keys sent back:

  • returnObj
    • Filters
    • [0]...[n]
      • Description
      • ControlType
      • Type
      • Value
      • Values
        • [0]...[n]
      • ExistingLabels
        • [0]...[n]
      • ExistingValues
        • [0]...[n]
      • uid
      • ColumnName
      • Parameter
      • OperatorFriendlyName
