Hi,
Sorry for the delay in getting back to you.
In the sample which is given in the previous post the DataSourceCachingMode is set as ViewState and not as None. Each and every time that you are clicking the checkbox the grid get rebinded with datasource. It is important to note that the callback is enabled for the Grid. And also the values are persisted and displayed through the Listbox. Please refer the video clip of this process from the below link:
