    The current ASP.NET Grid example demonstrates RadGrid's capability for inserting new data, updating existing data and deleting data against an EntityDataSource. The only thing that is required of you is to configure the entity data source by incuding the correpsonding database tables in the entity data model and set the following properties of the grid to true to propagate automatic update/insert/delete operations:

    • AllowAutomaticUpdates
    • AllowAutomaticInserts
    • AllowAutomaticDeletes

    What is on this example:
    • You can insert a new item using the [Add new record] button in the Command row.
    • You can edit an item using the Edit button (the first button in each row).
    • You can delete an item, using the Delete button (at the end of each row).
    • DefaultCS.aspx
    • DefaultCS.aspx.cs
    • styles.css
