Yuseff,

You cannot know when the user closes the browser or navigates away from your web site. In the same way, you do not need to clear a data grid. Once the browser has finished loading the page, the data grid doesn't exist on the server anymore. It's already unloaded from memory, so there is no reason to clear it.

If you want to prevent the datagrid from automatically reloading with the same data, just set the EnableViewState property of the grid control to False.
