Can't edit any row except the first row in Grid

Problem

The edited/deleted row always getting first row value in the Grid.

Cause

isPrimaryKey property is not set to the primary key column.

Solution

The edited/deleted row always getting first row value can be fixed by setting isPrimaryKey property of "columns" for primary key column in the data source. The editing functionalities can be performed based upon the primary key value in the selected row.
