From this post on the Infragistics forums I believe that you have a numeric column. This is not a recommended approach as that variable may change, so I suggest that you submit a new product idea to have the filter row added to the public API.
If this is the case then you should use a Numberic Editor Provider instead. You can do this on the following page: Another thing to note is that the default filter type is "All" so you'll also want to change this.
As far as I get your line of code you are interested in data rows only and the following row-related events are fired only for data rows as far as I'm aware(definitely not for headers or Summary rows from my experience): Server side: The Initialize Row event is raised when the grid binds to the records in the data source. Could you provide more information about your setup?
Web Data Grid offers 2 versions of such events so whatever you are attempting would probably have to do with these. My hunch is that somehow the logic for finding the grid isn't quite working for you, though I'd need to see more of your implementation to know what's going on.Web Data Grid Bug Fix Hidden columns appear visible after refreshing the page and showing the grid.Web Data Grid Bug Fix Exception is thrown on postback when binding grid that has grouped columns.There are more details on enabling filtering in the Filtering topic in the Net Advantage for ASP.
