[Solved] Add FilterDescriptors to Grid when Initializing

[mike]

I have a Grid that I am trying to pass filterdescriptors to when the page loads. The initial load is server side, then the subsequent loads will be ajax requests. 

My Model contains a GridCommand Property, I just don't know how to set the Filters on the view based on the filterdescriptors in the GridCommand.

Has anyone done this?

Hi,

You should be able to access the filter descriptors in the view and then configure the grid. How to enumerate the filter descriptors is shown in our custom binding demo (check the BindingHelper tab and the ApplyFiltering method).

Atanas,

I would like to do add a the filter descriptors that I set on my Model in the controller for the view so that they are initially set on grid.

.Filterable(filtering => filtering.Filters(filters =>
           filters.AddRange(_model.MyBuGridCommand.FilterDescriptors)))

Something like the above example.

Hi,

Unfortunately I have misunderstood your requirements and have mislead you with my previous reply. Please accept my apologies for that.

Currently there is no AddRange method and setting the filter requires an expression e.g.

filters.Add(o => o.ContactName).StartsWith("Paul");

There is a protected collection of FilterDescriptors however which perhaps can be used if made public. Would you like to try a build where this property is exposed so you can set it?

Sure that would be great to have that as public.

Atanas, did you find the solution to make the filters public? I changed the properties and tried to set like the following:

.Filterable(filtering =>  new GridFilteringSettings(){Enabled=true, Filters =  Model.MyBuGridCommand.FilterDescriptors} )

The problem I'm running into is that the Filters on a GridCommand are

IList<IFilterDescriptor> and the Filters on the GridFilteringSettings are 
List<CompositeFilterDescriptor>. Is there an internal method that will have the grid accept an Ilist
of IFilterDescriptors? I imagine this would be
similar to when you apply a filter manually during initializing.
