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/TechnologiesLimitedList
  • Type - GET.

 Test the APIs using POSTMAN.

Build a Kendo Grid with remote datasource

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

From the above code, you can notice that the Kendo Grid is constructed based on our remote datasource which is formed from REST API.

Pager Visibility in Kendo Grid

Pager Visibility attribute in a page-able property is used to make the pager visible or not, based on its requirement, just by changing the status of the attribute.

By default, the pager visibility will be true, which means that the pager is always visible in Grid even when the total amount of items in the datasource is less than a pageSize.

The Pager will be hidden when the total amount of items in the datasource is less than pageSize, by setting pager visibility as false.

Result
 
 
FIgure 3
 
So, by default, the pager alwaysVisible attribute is true .
 
Making alwaysVisible as false.
