Data Grid - Editing

This sample demonstrates how the igGrid Updating feature can communicate with the Grid MVC Helper wrapper to persist the changes on the server.

This sample is designed for a larger screen size.

On mobile, try rotating your screen, view full size, or email to another device.

Transactions used to log any changes made to the grid are kept locally in the browser until the igGrid.saveChanges API method is called to send a POST request to the Url indicated by the igGrid.updateUrl option. The Grid MVC Helper wrapper greatly simplifies the task of parsing and processing these changes on the server. The OrdersSaveData controller method uses a GridModel.LoadTransactions(string postdata) to deserialize the changes from the grid and processes them. Use the grid to add, edit, or delete single or multiple records. Press the "Save Changes" to send the changes to the server with an Ajax call.
