In normal web applications, we all have used Entry forms where Add, Edit and Delete
operation on records needs to be performed. But this always involves a server postback
for each operation. So the user has to wait until the operation is complete and
page is reloaded.
The following demonstrates a complete Entry system with the ability to display data
in a grid, add, update and delete the records without reloading the page. This has
been achieved through Update Panels and Triggers. The overall experience gives a
total desktop application feel.
