Syncfusion Grid - Server side paginated results

[Francis]

Hi all,      I want to show filtered results in a grid gathered from millions of data in our database. I would be handling the loading logic in the server side via ASP.NET Web API and render results via AngularJS.     Could you recommend an approach or solution for loading these million rows into a paginated grid wherein the data are lazy loaded or loaded on demand.             Each page is limited to 10 pages then if I want to go to the next page I would be requesting a call to the server to get data from the database.       Is this possible with Syncfusion Grid? The examples I have seen are only for grids that has all its data loaded already.     Anybody can shed light on this? Thanks.

Hi Francis, 

Thanks for contacting Syncfusion support. 

According to your requirement, you have try to perform server –side paging operation in Grid.  To perform serve side operations(paging, filtering, sorting) in webapi adaptor, use ODataQueryOptions. ODataQueryOptions parameter in server side controller which contains all the required parameters for performing server side operations such as paging, sorting and filtering. 

We have created a sample in Angular JS with Web API and please download from the following link.  

Sample: http://www.syncfusion.com/downloads/support/forum/131642/ze/ServerOperations1927520951 

Find the code example:  

<div class="row"> 

    <div ej-grid id="Grid" e-width="500px" e-datasource="data" e-allowgrouping="true" ------ > 

        <div e-columns> 

            ------------------------------- 

       </div> 

    </div> 

 

</div> 

 

<script> 

    angular.module("GridCtrl", ["ejangular"]) 

        .controller("bodyCtrl", function ($scope) { 

 

        //Provide the datasource to the grid. Here the WebApiAdaptor is used. 

        $scope.data = ej.DataManager({ url: "/api/Orders", adaptor: "WebApiAdaptor" }); 

 

        $scope.tools = ["add", "edit", "delete", "update", "cancel", "search"]; 

 

    }); 

</script> 

 

--------------------------------------------- 

public PageResult<OrdersView> Get(ODataQueryOptions opts) 

        { 

            List<OrdersView> ord = db.OrdersViews.ToList(); 

 

            return new PageResult<OrdersView>(opts.ApplyTo(ord.AsQueryable()) as IEnumerable<OrdersView>, null, ord.Count); 

        }
