ASP.Net Programing Laungage

ReorderList is an ASP.NET AJAX control that implements a bulleted, data-bound list with items that can be reordered interactively.This is useful if the data is only to be ordered.The ReorderList is a very powerful piece of the ASP.NET AJAX Control Toolkit. It gives you the ability to interactively reorder a list of items.The ReorderList can handle reorders in two ways, either via a callback or via a postback.the ReorderList can automatically perform reorders.

If the data you are displaying has a field that determines sort order (e.g. the select query is sorted by this column), and that column is of an integer type and if its SortOrderField property is set. The ReorderList can also bind to any data source that implements IList (such as Arrays).
