Tab not refreshing.

Hi Reader,   I have created a page in which I have used tab container. There are three tabs and each contains data grid 2 displaying data of different status (Inprogress, Completed, Aborted). In each data grid I am using checkbox for different purpose (for selecting items). Now I want if I select checkbox of one tab then others should be false (unchecked). How Can I achieve this? Please suggest
