Automatic CRUD Operations

RadDataForm provides built-in support for automatic CRUD operations thus allowing you toinsert/update/delete records using very little code. In order to take advantage of this functionalityyou should configure the control as follows:

1. Bind it to a DataSource control that supports automatic data source operations.

2. Add the primary key field from the database table as a DataKeyName.

3. Define the respective edit and insert templates and assign appropriate commands for the buttons.
