Default ListView Gridview question

What are the advantages of using a listview over a gridview and vice a versa? And do not listviews use specialized item and group placeholders that gridviews don't use? Secondly real quick what is the advantage that LINQ and ETF, entity framework have over heavily typed datasets? Are not heavily typed datasets, more apt to require bigger footprints than LINQ and ETF? Are not heavily typed datasets more apt to eat more resources like Network Bandwidth and CPU cycles? Also are heavily typed datasets are the same as .xsd files or am I mistaken about that?

Thanks once again.

Hi there,

The ListView supports more scenarios such as multiple columns using ul and i elements. The GridView is better at true tabular data with paging and sorting.

With regards to DataSets (which are called *strongly* typed DataSets): they carry a lot of overhead (try serializing one to xml to see what I mean,) are harder to configure, don't support complex object graphs, don't allow you to define your classes, don't allow fleible sql queries, to name a few disadvantages. In other words, they are not the recommended data access technology anymore.

And no, xsds are not the same as DataSets, although a strongly typed DataSet uses an xsd.

Hope this helps,
