In contact list, I want to select all(multiselect) the items automatically for bulk operations.
Because of performance page is having load more option and when ever we query the collection model we are getting only displayed entity list not the complete list.
Is there any way to ready the complete list without multiselection.
Are you attempting to programmatically select all items in the grid? If so, this is currently not something that is supported by the grid control.
Instead, having the end user trigger the “Select All” option in the grid will return all items in the list and not just the current page that is loaded by the UI. In this way, it is possible to perform a bulk operation on all items in a list.
