UserRegistration Login and Forget Password with Database in asp.net

UserRegistration Login and Forget Password with Database in asp.net


Create User Registration Form In Asp.Net


Creating User Registration Form Example In Asp.Net

In this post i am explaining how to create user registration or signup page in asp.net with sql server database using C# and VB.NET.

Creating user registration form in asp.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.







We can also Create Users with Membership Provider programmatically Or usingCreateUserWizard, You will also need a Login Page

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.

HTML SOURCE OF PAGE
   1:  <table>
   2:  <tr>
   3:  <td>First Name:</td>
   4:  <td><asp:TextBox ID="txtFirstName" runat="server">

Create Login Page Example In Asp.Net

To create Login Page Example, i have added a new form and placed 2 textboxand one button on it.
