🧾 Program: Create ASP.NET Web Application for Name, Password, and Age Validation
🪜 Step 1: Create New Web Application

Open Visual Studio → File → New → Project.

Select ASP.NET Web Application (.NET Framework).

Name it, e.g., UserValidation.

Choose Empty → Tick Web Forms → Click Create.

🪜 Step 2: Add a Web Form

Right-click on the project → Add → Web Form.

Name it Register.aspx.

🪜 Step 3: Switch to Design View

At the bottom of the editor, click Design tab.

You can now drag and drop controls visually from the Toolbox.

🧱 Step 4: Add Controls
👉 (a) Name Field

Drag Label → Set Text = "Name", ID = Label1

Drag TextBox → ID = TextBox1

Drag RequiredFieldValidator → set properties:

ControlToValidate = TextBox1

ErrorMessage = Name is mandatory

👉 (b) Password Field

Drag Label → Text = "Password", ID = Label2

Drag TextBox → ID = TextBox2, TextMode = Password

Drag RequiredFieldValidator → set:

ControlToValidate = TextBox2

ErrorMessage = Password missing

👉 (c) Confirm Password Field

Drag Label → Text = "Confirm Password", ID = Label4

Drag TextBox → ID = TextBox4, TextMode = Password

Drag CompareValidator → set:

ControlToValidate = TextBox4

ControlToCompare = TextBox2

ErrorMessage = Passwords do not match

👉 (d) Age Field

Drag Label → Text = "Age", ID = Label3

Drag TextBox → ID = TextBox3

Drag RangeValidator → set:

ControlToValidate = TextBox3

MinimumValue = 20, MaximumValue = 80

Type = Integer

ErrorMessage = Age must be between 20 and 80

🪜 Step 5: Add Submit Button

Drag Button from Toolbox → ID = Button1

Set Text = Submit


🧱 (Email Field)

Drag Controls:

From the Toolbox → Standard, drag a Label control →

Set Text = "Email"

Set ID = LabelEmail

Drag a TextBox →

Set ID = TextBoxEmail

Add Validators:

RequiredFieldValidator

ControlToValidate = TextBoxEmail

ErrorMessage = "Email is required"

RegularExpressionValidator

ControlToValidate = TextBoxEmail

ErrorMessage = "Enter a valid Email Address"

ValidationExpression = ^\w+@[a-zA-Z_]+?\.[a-zA-Z]{2,3}$



🧱 (User ID Field)

Drag Controls:

From Toolbox → Standard, drag a Label →

Set Text = "User ID"

Set ID = LabelUserID

Drag a TextBox →

Set ID = TextBoxUserID

Add Validators:

✅ (a) RequiredFieldValidator

Ensures the User ID field is not left empty.

<asp:RequiredFieldValidator ID="rfvUserID" runat="server"
    ControlToValidate="TextBoxUserID"
    ErrorMessage="User ID is required"
    ForeColor="Red">
</asp:RequiredFieldValidator>

✅ (b) RegularExpressionValidator

Ensures:

At least one uppercase letter

At least one digit

Length between 7 and 20 characters

Regex Expression:

^(?=.*[A-Z])(?=.*\d).{7,20}$
