In this post i am explaining how to create user registration or signup form in asp.net with sql server database using C# and VB.NET.
For this first of all we need to create a table in sql server database to store user registration data.
I have created a table named Users for this example with columns shown in image below.
Place textboxes on the form for entering name,username,password,address,email etc.
Set Textmode property of password textbox to password to display * character instead of text entered.
Associate RequiredFieldValidators with textboxes as shown in HTML source.
Place one Label and Button to save the data.
