By design, the Change event fires every time when a table row/cell in the grid is selected including the already selected row/cell. However, in the Change event handler, the currently selected row can be conditionally checked if is equal to the last selection using a global variable. For more information please refer to the following forum thread discussing this topic:
Let me know if you have any questions.
