Thanks for your interest in Syncfusion products.
From your code example, we could see that you have specified the “pageSize” property of the Grid pageSettings as string which is supposed to be an integer value.
Since the pageSize property is defined as a string value, upon paging the whole data is fetched thus resulting the reported behavior. So we suggest you define it as integer value. Please refer to the below API documentation link for more information
