How to delete all record from DataSource without looping?

[Ambica]

Hi all,

I am wondering is there any method to remove all record from dataSource ? and then sync(), so that it'll clear all record from DB .

Have scenario like i want to delete 500 records then add 20 - 30 records. I can do it with loop it causing delay. 

Please help me out

Thanks in Advance

Hello Ambica,

 Currently the Kendo DataSource doesn't provide any API fore deleting all records. Looping is the only supported way.

You could set the DataSource batch mode to true. That way all of your deleted records are sent in one request to the server. And then all of your added records are sent in a separate request to the server. Then on the server-side you would have to loop through each record to add/remove them from your data store. The benefit here is that the looping is done on the server, and since the requests are asynchronous, the client is not held up.
