I wanted to add buttons to my DataGrid, but I didn't want a button on each line that said 'Edit' or 'Update'. I wanted each button's text value to vary based on cell contents. It just seems more intuitive and less amateurish to use data to populate the buttons as opposed to creating dozens of buttons all of which carry the same text. Why have an 'Edit' button next to some cell value when the cell could contain the button?...

The GridView is a very powerful control and has all the features including paging/sorting etc. But while using GridView in your project, you have to assign the PageSize property of the GridView programmatically, which users then cannot change. Sometimes, users require the feature to change the page size so that they could view more/less records per page. With one of my projects, I was asked to develop such a control with custom paging. I am sharing this with you so that you don't have to rework ...

The GridView control provides you with an easy way to display the number of items on a page without taking much space, with the help of paging. You can enable the paging feature in the GridView control in seconds. The built-in paging is pretty good if you are fetching less than 100 items. As soon as the number of items increases, the performance suffers. The main reason for the performance kill is that whenever you go to a new page of the GridView, it fetches all the items from the database. In ...
