Client side binding and caching

[Charles]

Hi,

I know it is possible to setup client side caching declaratively with the RadGrid using the ClientSettings.DataBinding.EnableCaching setting.
However, is it possible to do this with programmatic client side binding?
I am using set_dataSource() and dataBind() methods in Javascript to do the client side binding and I would like to also use caching to implement sorting purely on the client side without any server side callbacks.
Is this possible?

Many thanks,
      Charles Gamble.

Hi Charles,

This is possible, you need to cache the data returned from your web service before binding the grid. Then, use RadGrid's client-side OnCommand event to listen for sort commands. You can then retrieve the sorted field and sort order from the command arguments, sort your data using javascript and pass RadGrid the updated data source using RadGrid.get_masterTableView().set_dataSource(). Finally, call the master table .dataBind() method to bind the grid. You should have sorting working OK.

Thanks for the reply.
It would be really nice if the Grid control provided this functionality itself instead of having it to do it by hand :)
Is there anything in the pipeline for this?

Data operations like sorting, filtering and data editing are not implemented on the client-side. With client-side databinding, these operations are performed either in your web service after a request, or the client-side implementation is left to the user to implement. We do not have any specific plans to provide client-side data editing with RadGrid.
