The BatchEditChangesPreviewShowing event handler receives an argument of the ASPxClientCancelEventArgs type. The following properties provide information specific to this event.
|cancel||Gets or sets a value indicating whether the action which raised the event should be canceled.|
The ASPxGridView control allows you to modify a batch of grid data on the client side and send it to the server in a single request. All user changes are maintained on the client side until the Save changes button is clicked, or all changes are canceled by clicking the Cancel changes button. The Preview changes button allows switching the grid to Preview Changes mode and manage modified rows.
The BatchEditChangesPreviewShowing event occurs when an end-user has clicked the Preview changes command button. To cancel the current operation, set the event parameter's cancel property to true.
