You can also loop through all the texbox controls and can check if it is empty. if a texbox is empty skip out of the loop and tell the user that the textbox is empty. This will shorten the coding and will fetch the result in a faster way.

In an ASP.NET Web page, you can set to two culture values, the Culture and UICulture properties. The Culture value determines the results of culture-dependent functions, such as the date, number, and currency formatting, and so on. The UICulture value determines which resources are loaded for the page.
