Ajax Grid and ServerOperation(false)

[Robert Madrian]

Hi,

I have tested the differences between setting ServerOperation(true) and ServerOperation(false)...

• if I set it to false no progress spinner is displayed during request the of the data - why?
• if I set false it is not enough to use $("#grid").data("kendoGrid").dataSource.page(1) to refresh the data - I have to set:
  

   

  $("#grid").data("kendoGrid").dataSource.read();
  $("#grid").data("kendoGrid").dataSource.page(1);

   

this is because of the Client side paging?

Are there other differences between this modes which I have to consider?
(I didn't find detailed information about ServerOperation(true/false)) and it's consequences)

Hello Robert,

When ServerOperation is enabled, all data operations like paging, sorting, grouping, etc. will be performed on server-side. When they are disabled, those operations will be performed on client and the entire data set will be available for the DataSource:

• http://docs.telerik.com/aspnet-mvc/helpers/grid/binding/ajax-binding#enable-client-data-processing

As for the progress indicator, since no requests are made when the server operations are disabled, no progress indicator will be displayed.

If any other questions arise on this matter, please feel free to contact us again.

I'm binding server side data with kendo grid data source on ajax success.But i also want refresh grid after data binding with grid.datasource and also need to reset page number. But i don't want to call read method for server side request. i want to refresh grid with existing updated datasource. Every time when i trying to reset page using grid.datasource.page(1) , it's calling read method that i don't want. Please suggest me..

Hi, Afshin,

When the UI for ASP.NET MVC Grid is configured for server operations, the only available data is the current page and pageSize. It is expected that when the data source page() method is used, the grid must make a request to obtain that data.

To start using client-side data and not make requests when paging, you should change the data source with the setDataSource() method:

https://docs.telerik.com/kendo-ui/api/javascript/ui/grid/methods/setdatasource

In case you require further assistance, provide any code snippets that are related to the scenario.
