Using WCF to provide data to Grid

[Chris Whisker]

Hi, 

I am attempting to create a grid that uses a WCF service as the datasource it is bound to. This has started well... I am able to pass back the data and have incorporated paging & sorting.

I am now looking at incorporating the Grouping and Filtering features, however this is proving problematic.

What I would like to do is pass the 'DataSourceRequest' directly to WCF as it contains all the arguments regarding the sorting, filtering & grouping in it

e.g. 

public ActionResult Index([DataSourceRequest(Prefix = "Grid")] DataSourceRequest request)

        {

            if (request.PageSize == 0)

            {

                request.PageSize = 10;

            }

 

            MvcApplication3.psr.ProductServiceClient psrc = new MvcApplication3.psr.ProductServiceClient();

 

             ResultData results = psrc.KendoGridQuery(DataSourceRequest);

 

            ViewData["total"] = results.Count;

          

             return View(results.Data);

         

        }

I then tried to add the Kendo.MVC library to my WCF project as a reference library so that I would be able to use the DataSourceRequest type.... However when I add the Kendo.MVC.dll as a reference and then compile the project it is unable to import the Kendo namespace.

I assume this is because the wrapper will only work within a MVC project?

Is it possible to add the data types from the MVC wrapper to my WCF project?

Thanks

Chris

Hi Chris, 

Kendo.Mvc.dll is indeed intended to be used in ASP.NET MVC applications. If you want to refer it from your WCF project you also need to refer to all assemblies that Kendo.Mvc.dll depends on. Those assemblies are:

• Microsoft.CSharp
• System.ComponentModel.DataAnnotations
• System.Configuration
• System.Core
• System.Data
• System.Data.DataSetExtensions
• System.Drawing
• System.Runtime.Serialization
• System.Web
• System.Web.Abstractions
• System.Web.Extensions
• System.Web.Mvc
• System.Web.Razor
• System.Web.Routing
• System.Web.WebPages
• System.Web.WebPages.Deployment
• System.Web.WebPages.Razor
• System.Xml

Also your code currently may not compile because you are using the type DataSourceRequest instead of the request parameter:

old:

ResultData results = psrc.KendoGridQuery(DataSourceRequest); 

new:

ResultData results = psrc.KendoGridQuery(request);
