It does not matter if paging is disabled

<kendo-grid name="grdAfdeling" selectable="true" on-change="onChangeAfdeling" deferred="true">
            <datasource server-operation="false" type="DataSourceTagHelperType.Ajax">
                <transport>
                    <read url="/Medarbejder/Hent_Medarbejder_Afdeling" data="hentAfdID" />
                </transport>
            </datasource>
            <scrollable enabled="false" />

It look likes the page-size is default 20 even if I dont use paging

Hi Christian,

By default, if there is no page-size attribute present, the data will be visualized on one page. Can you verify that there is no external logic responsible for the page size of the grid?

If only 20 records are loaded and the page-size attribute is not present, probably the server returns only 20 items at a time. Please ensure that the records returned from the server are more than 20 and they have not been modified before being passed to the grid.

In case the issue persists, please elaborate in further details on the exact set-up of the data source or share any information that you find relevant to the case.


Kind regards,

Hi Tsvetomir

There is  no external logic responsible for the page size  

There is no page-size attribute in the grid

The server loads more than 20 records

If I set a page-size = 999 I get all data

Hi Christian,

I have noticed that you have set the data source type to Ajax. When you set the data source, the Kendo UI Grid provides a fleet of configurations to make the data source compatible with the ToDataSourceResult() method. More information about the method of interest can be found in the Important note of the following article:

https://docs.telerik.com/aspnet-mvc/helpers/grid/binding/ajax-binding

Also, return a plain array from the server since when you set the data source to Ajax, the returned result will be converted to a state which is compatible with the Ajax type data source. Try removing the type attribute from the DataSource declaration. 

As a side note, the pageable attribute by default is disabled and the pageSize attribute has no default value. More information can be found in the following articles:

• pageable
• pageSize

Attached you can find a sample project demonstrating how the grid visualizes the whole data. Check it out and in case the issue persists, please modify the project and send it back to me. 


Kind regards,
