Hi,

I need somebody from Telerik to answer these questions:

1. A grid with AllowPaging property to True and PageSize=15, and filtering, groping, etc, where exactly store all the records?

2. The same grid in question 1, when go to the next page, from where the grid load the next 15 records?

3. A grid with AllowPaging property to True and PageSize=15, and no filtering, no groping, etc, where exactly store all the records?

4. The same grid in question 3, when go to the next page, from where the grid load the next 15 records?

Note: We are not using LinqDataSource or EntityDataSource and we are using build-in paging.

thanks.

Hello Marietta,

Concerning questions 1 & 3:
Regardless of Paging, Filtering and Grouping being enabled, all the 15 records are always rendered on the server and sent to the client, so essentially in run time they are contained in the browser in the form of html mark-up. 

Regarding questions 2 & 4:
No matter if filtering, sorting and grouping are enabled, the page command is one of RadGrid's commands that implicitly require the grid to rebind. The latter means that the on each page change the grid will query its data source and fetch the records from there.

I hope this helps.

Kind regards,
