You want to use a
GridView with sorting and paging.
Enable the sorting and paging functions of the
GridView and add custom coding to display the sort order in the header of the current sort column. Figure 2-16 shows a typical
GridView with sorting and paging implemented. Examples 2-39, 2-40 through 2-41 show the .aspx file and the code-behind files for an application that produces this output.
Figure 2-16. Combining sorting and paging in a GridView output
GridView provides the ability to perform sorting and paging without having to write any custom code. But because the
GridView does not provide any indication of the current sort column or order, you may want to write a small amount of custom code to accomplish this, as described in this recipe.
