This article explains how to create a multi-step registration form with Kendo UI MVVM pattern using Web API2 and Entity Framework 5.
Just create a Web API project as shown in Figure 1 and Figure 2.
Figure 1
In my case I named the project MultiStepRegistration.
Figure 2
The Project structure will be as shown in Figure 3.
Figure 3
Here I am using the Entity Framework Code First technique to connect with the database.
Create a model class and name it RegistrationMultiStep.cs.
Use the following code in that class:
- public class RegistrationMultiStep
-
- {
-
- [Key]
-
- [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
-
- public int UserID {
- get;
- set;
- }
-
- [Required]
-
- public string FirstName {
- get;
- set;
- }
-
- [Required]
-
- public string LastName {
- get;
- set;
- }
-
- [Required]
-
- public string Email {
- get;
- set;
- }
-
- [Required]
-
- public DateTime DOB {
- get;
- set;
- }
-
- public string State {
- get;
- set;
- }
-
- public string City {
- get;
- set;
- }
-
- [Required]
-
- public string Country {
- get;
- set;
- }
-
- [Required]
-
- public string UserName {
- get;
- set;
- }
-
- }
Create one more model class and name it MultiStepRegistrtionContext.cs.
Use the following code in that class:
- public class MultiStepRegistrtionContext: DbContext {
- public MultiStepRegistrtionContext(): base("name=TestConnection") {}
- public DbSet < RegistrationMultiStep > MultiPathRegistration {
- get;
- set;
- }
- }
Modify your connection string in the web config file as in the following:
- <connectionStrings>
-
- <add name="TestConnection" connectionString="Data Source=Server name;Initial Catalog=Database Name;Integrated Security=True" providerName="System.Data.SqlClient" />
-
- </connectionStrings>
Build your application once before starting scaffolding. Add a controller as shown in Figures 4 & 5.
![]()
Figure 4![]()
Figure 5
The preceding procedure will scaffold the REST full service in the RegistrationMultistepsController.
You will get some pre-defined HTTP GET, POST, PUT and DELETE requests/responses in the RegistrationMultiSteps Controller. Modify the code based on your application requirements. For this example I did not modify the code.
To insert a record into the RegistrationMultiStep table we should use HTTP POST requests and responses.
Before implementing it in the Kendo UI once check that the service is in Postman / Fiddler.
Design the UI to consume the service.
I have used KendoUI with the MVVM pattern.
Here is my design:
The View Model Script:
- $(document).ready(function() {
-
- var viewModel = kendo.observable({
-
- firstName: "",
-
- MiddleName: "",
-
- Email: null,
-
- selectedDate: null,
-
- isPrimitive: false,
-
- isVisible: true,
-
- isEnabled: true,
-
- confirmed: false,
-
- City: null,
-
- State: null,
-
- Country: null,
-
- UserName: null,
-
- Passsword: null,
-
- ConfirmPwd: null,
-
- });
-
- kendo.bind($("#example"), viewModel);
-
- });
KendoValidation and Ajax script:
- function RegisterUser() {
- var validator = $("#RegistrationForm").kendoValidator({
- rules: {
- PasswordRequired: function(input) {
- var ret = true;
- if (input.is("[id=Password]")) {
- ret = $("#Password").val().length > 0;
- }
- return ret;
- },
- PasswordLength: function(input) {
- var ret = true;
- if (input.is("[id=Password]")) {
- ret = $("#Password").val().length > 6;
- }
- return ret;
- },
- ConfirmPasswordRequired: function(input) {
- var ret = true;
- if (input.is("[id=Confirmpassword]")) {
- ret = $("#Confirmpassword").val().length > 0;
- }
- return ret;
- },
- CheckConfirmPassword: function(input) {
- var ret = true;
- if (input.is("[id=Confirmpassword]")) {
- ret = $("#Password").val().trim() == $("#Confirmpassword").val().trim();
- }
- return ret;
- },
- RequiredEmail: function(input) {
- var ret = true;
- if (input.is("[id=Email]")) {
- ret = $("#Email").val() != '';
- }
- return ret;
- }
- },
- messages: {
- PasswordRequired: "Please enter confirm password",
- PasswordLength: "Password must be of minimum 7 characters",
- CheckConfirmPassword: "Your passwords do not match",
- ConfirmPasswordRequired: "Please enter confirm password",
- RequiredEmail: "Email is required",
- }
- }).data("kendoValidator");
- if (validator.validate()) {
- alert("validation Success")
- $("#Uploadwindow").kendoWindow({
- content: {
- template: "<div class=\"form-inline\"><div class=\"col-lg-5\"><p>Please wait while we register your account. You will be redirected to home page automatically.</p></div>"
- },
- modal: true,
- width: 500,
- title: "User Registration"
- });
- uploadWindow.open();
- $.ajax({
- cache: false,
- async: false,
- type: "POST",
- url: "http://localhost:61832/api/MultiStepRegistrations",
- data: {
- FirstName: $("#fname").val(),
- LastName: $("#lname").val(),
- Email: $("#Email").val(),
- DOB: $("#Dob").val(),
- City: $("#City").val(),
- State: $("#State").val(),
- Country: $("#Country").val(),
- UserName: $("#UserName").val(),
- },
- success: function() {
- alert("Your Record Has Been Saved SuccessFully!");
- uploadWindow.close();
- window.location = SubmitURL;
- },
- error: function(xhr, status, error) {
- alert("This is inside Error function of Ajax Call For Update Event Function");
- }
- });
- }
- }
The registration form consists of three steps.
Step 1: Personal Details
In the browser it is as shown in Figure 6.
