MVCxBatchUpdateValues<T, S>.DeleteKeys Property
Contains a list of keys that correspond to grid records deleted on the client side in batch edit mode.
In batch editing mode, all end-user changes are maintained on the client side until the Update button is clicked, or all changes are canceled by clicking the Cancel changes button. When an end-user clicks Update, the grid extension sends a callback with user changes (the MVCxBatchUpdateValues<T, S> object) to the server side. This callback is handled by an Action in the Controller, defined using the BatchUpdateRouteValues property. This Action method receives the MVCxBatchUpdateValues<T, S> object as parameter and allows you to apply all the changes made on the client side to the grid's data source.
The DeleteKeys property contains a list of keys that correspond to deleted grid records on the client side in batch edit mode.
