Take Filter and apply as LINQ .Where()

[Justin Hunter]

Hey all,

I was wondering if there was the ability to intercept the Filtering event for the RadGrid and extract the filter and apply it as a Where(...) to a completely separate container. We require this as we have a map and we want the filtering of the grid to affect the aggregation colours of the map.

How difficult / possible is this?

Hello,

We have a public static class with extension methods called Telerik.Windows.Data.QueryableExtensions.

It has a Where extension method for an IQueryable instance which accepts a collection of FilterDescriptors and translates them to a Where LINQ clause on the the IQueryable and returns it:

public static IQueryable Where(this IQueryable source, IEnumerable<IFilterDescriptor> filterDescriptors)

There are a bunch of other methods there as well.
