I am currently working on a project which uses the RadGridView, part of the required functionality is to hide and show records based on various user interaction with the grid, it would appear the best way to get this to work is using a CompositeFilterDescriptor and add and remove the filters as required.

My issue is as follows, the project has been written using MVVM and from all the reading i have done it doesn't seem possible to use binding for the indvidual FilterDescriptor lines, the RadGridView in question is contained with in a datatemplate (and there maybe more than one on the screen at one time) so it's can't be accessed directly from the code behind.

So my question is, is there anyway of changing the FilterDescriptor lines with out directly accessing the grid from the code behind.

Hi,

 You could directly change the instance of the CompositeFilterDescriptor you have added to the FilterDescriptors collection of the GridView.
