Filtering

[sitefinitysteve]

What's the best way to do optional filtering?

So for example if this is my main query

List<ViewAllRequest> requests = (from r in scope.Extent<ViewAllRequest>()
                                 select r).ToList();

But the user has specified they want 3 (of 10 possible) filters applied...like Name, or Email...

How do I then filter that result set down, or BETTER, filter with the initial query?

Hi Steve,

I recommend you using our code library example “Using Telerik OpenAccess ORM with Dynamic LINQ”. It demonstrates how to create dynamically Linq queries.
Other approach you could use is the IQueryable interface. It provides functionality to evaluate queries against a specific data source:

IQueryable<Product> query = context.Products;

if (!string.IsNullOrEmpty(searchString))
{
   query = query.Where(c => c.ProductName.Contains(searchString));
}

I hope this solution provides helpful for you.

All the best,
