TrackbackEvery one of us has used paging in our projects to display tabular data in DataGrids or GridViews or in the more recent and more flexible ListViews.
The problem we often face is when the data is less the paging works fine, but as the data starts to increase the page load times start increasing. The main reason for this is because we tend to bind the grids with entire data table and then use the built in functionality for paging.
