In this example, I am going to retrieve values from categories table of Northwind database.

Explore the Telerik Public Issue Tracking system and vote to affect the priority of the items I understand by using the Data Member Binding attribute the column is visible in the Old Values, which is great.

The event handler receives an argument of type SQLite Row Updated Event Args containing data related to this event.
The following SQLite Row Updated Event Args properties provide information specific to this event.

By performing above coding we would avoid the error - Specified cast is invalid.
Then we need to override the gridview's Row Updating event.
In this event you can write code to get the newvalue of checkbox's checked property only.
A datakey represents the primary key field or field of a record that can uniquely identify it in a data-bound control. Row Index represents the index of the particular row.
