Integrating Kendo Sortable In Grid

Introduction

In this article, I am going to discuss how to integrate the Kendo Sortable control in the Grid so that we can drag and drop the records within a Grid. 

Remote Data Source for Kendo Grid

I am going to use the API response given below to construct my remote data source for Kendo Grid which was created in my previous article.

API - http://github-ci-staging.azurewebsites.net/api/Technologies/TechnologiesList

Type - GET.

Testing the APIs, using POSTMAN.

Create a new HTML page. In my case, I named it KendoSortableGrid.cshtml.

  59.   
  60.     </div>  
  61.   
  62.   
  63. </body>

From the code given above, it is obvious that we have constructed a data source for the Kendo Grid using our API, i.e., http://github-ci-staging.azurewebsites.net/api/Technologies/TechnologiesList.

Kendo Sortable

Kendo Sortable makes the DOM element sortable by drag and drop with a mouse or a finger in mobile device.

"Change event" definition of the Kendo Sortable is used to reorder the index of the data item which is in Grid data source.

  • Filter - This determines which items are sortable
  • Container - Determines to which boundaries the hint movement will be constrained
  • autoScroll - To enable scrolling when there is drag and drop within scrollable Grid
