Hierarchical Grid - Editing
In this sample the igHierarchicalGrid Updating feature communicates with the Grid MVC Helper wrapper to persist the changes on the server in a DataSet object.
This sample uses CTP (Community Technical Preview) features. The API and behavior may change when these features are released with full support.
This sample is designed for a larger screen size.
On mobile, try rotating your screen, view full size, or email to another device.
The igHierarchicalGrid Updating feature uses transactions to log any changes made to the grid. These transactions are kept locally in the browser until the igHierarchicalGrid.saveChanges API method is called to send a POST request to the URL indicated by the igHierarchicalGrid.updateUrl option. On the server, these transaction should be parsed and processed, and the Grid MVC Helper wrapper greatly simplifies this task. The EditingSaveChanges 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 in either the root or child layout. Press "Save Changes" to send the changes on the server with an Ajax call.
