display just keeps repeating and I have to write a bunch of code to change the sort order
of the data. How do I create a table-like display that will show a set number of rows at a
time and let me sort the data?
Technique
The DataGrid control is by far the most flexible and powerful of the controls used in
ASP.NET for displaying data on your Web page. It gives you the ability not only to list
data, but also to page through it and sort it nicely with headers, and even to edit data. This
last feature will be saved for the next How-To.
To perform the other tasks, you will use a combination of setting properties at design
time and programming some events. In particular for the DataGrid control, you will add
code to events raised by sorting and paging.
This How-To will use the DataGrid bound at design time. You will also see a simple
example of using the DataView object for sorting your data.
