EmptyDataText and EmptyDataTemplate properties of asp.net gridview control - Part 27

By default an asp.net gridview will not display anything on the webform, if there are no rows in the datasource to which the gridview is bound. For example, let us say we are binding a gridview control to tblProduct table. If there are no rows in this table, then the gridview does not render any thing on the webform. If there are no rows, I want the gridview to display a message stating - "There are no products to display". There are 2 ways to achieve this.
1. Set EmptyDataText property of the gridview control

OR

2. Use EmptyDataTemplate

EmptyDataRowStyle Property can be used to set the display styles of the empty data row.

If you set both, EmptyDataTemplate is used instead of EmptyDataText. The difference, between the 2 is that, if you want to have greater on what you want to display, then use EmptyDataTemplate.

For example, I want the gridview to render an HTML table with a header and a message

To achieve this I would use EmptyDataTemplate
