How To Apply Filters to exsisting LinkToSql Dynamic Data Site

Aug 26, 2009 at 9:12 PM


I have web app that I'm trying to construct, and I would like to include these handy filters to my App.

I have followed the turturiols that you have created from start to finish about 4 times now and I can't get anything to work. 

Below is a copy of my List.aspx page, that I have been trying to get working..this is a page from my custom page folder. I have added in the warning I get when I try to build/run this (it is in the middle of the code...I changed the text black). 

Any Help would be much appreciated..I'm new dynamic data but I have some apps that work great without this filtering, but I would sure like to use it.

Hi, I have been trying the exact same thing using a custom list page and getting the same error.  Any input would be very helpful.

Couple of things:

First, I see that you are suing the QueryExtender which is part of the Dynamic Data Preview.  I am not sure how this is going to work with my Dynamic Data Filters targeting the 3.5 SP1 Framework version. 

Second, based on that error, I believe you need to check you Matrixes\List.aspx.designer.cs file.  I believe it is going to say that GridDataSource is of of type LinqDataSource, not DynamicLinqDataSource which it needs to be.

Hope that helps.

Thanks!!  I will switch to 3.5 SP1 and give it a try.
