Azure SQL Manager

Azure SQL Manager is a simple management portal for the remote developers to add their own IP address to Azure SQL Server. No need to ask them what is their IP address let them assign it!

How Do You Use It?
1. First create an account for your users or developers using ASP.NET MVC Identity. 
2. Create a certificate and upload the certificate in azure subscriptions and also put it to your App_Data folder. There are two files if you create the certificate, .cer and .pfx

Code Please!

in /Infrastructure/AzureSqlManagerRepository.cs

private SubscriptionCloudCredentials getCredentials(string subscriptionId, string path){
     var cert = new X509Certificate2(path, "CERTIFICATE_PASSWORD_HERE", X509KeyStorageFlags.MachineKeySet);
     return new CertificateCloudCredentials(subscriptionId, cert);
change the CERTIFICATE_PASSWORD_HERE to your certificate password.

and in 

private string BuildPath(){
    return Server.MapPath("~/App_Data/your_certificate_name.pfx");

private static string _subscriptionId = "azure_subscription_id_here";
Assign the path, point it to your certificate and change the value in _subscriptionId to your Azure Subscription ID

Knockoutjs CRUD

A friend ask me to create a sample CRUD in knockoutjs, so I decided to put it in my blog and share it.

First Step: 
Add knockoutJS to your project you can download it to knockoutjs website then start with view model script.

var viewModel = function(){
    var self = this;


    var model = new viewModel();


Next the letter C in CRUD, Create. Let's add a html view for our create.

<form data-bind="submit:Create">
    <input type="hidden" data-bind="value:id">
    <input type="text" data-bind="value:description">
    <input type="submit" value="submit">

for our create knockoutjs script, Add id and description property as observables. Then function for saving the data into array that is observableArray.

self.list = ko.observableArray([]); = ko.observable("");
self.description = ko.observable("");
self.action = ko.observable("add");

self.Create = function(){
    if(self.action() == "add"){
        var id = (self.list().length) + 1;
           Description: ko.observable(self.description())

Next is Read, and let's add static data in observableArray and read function: = ko.observableArray([
   {"ID":1, "Description":"Tops"},
   {"ID":2, "Description":"Dresses"},
   {"ID":3, "Description":"Tees"},
   {"ID":4, "Description":"Blouses"},
   {"ID":5, "Description":"Shorts"},
   {"ID":6, "Description":"Pants"},
   {"ID":7, "Description":"Denim"},
   {"ID":8, "Description":"Bags"},
   {"ID":9, "Description":"Jackets"},
   {"ID":10, "Description":"Skirts"},
   {"ID":11, "Description":"Accessories"}]

self.Read = function(){
         Description: ko.observable(item.Description)

Let's add <table> html tag to display our data

    <tbody data-bind="foreach:list">
        <td data-bind="text:ID"></td>
        <td data-bind="text:Description"></td>
            <a href="#" data-bind="click:$root.Delete">Delete</a> | 
            <a href="#" data-bind="click:$root.Edit">Edit</a>

Now we have a data, let's do an U in CRUD as Update:

self.Edit = function(data){


Then the D as Delete

self.Delete = function(data){
   if(confirm("Are you sure you want to delete this data?")){

Overall this is what it looks like in fiddle

Overall a simple approach for CRUD in KnockoutJS

Happy Coding!

How to pass data from knockoutjs to ASP.NET MVC view model

You can pass a data using your model in knockoutjs to ASP.NET MVC View model as argument in your action methods.  

First create your model in knockoutjs

var model = function(){
     var self = this:
     self.FirstName = ko.observable();
     self.LastName = ko.observable();

Then use this knockout model to pass the data through ajax.

var viewModel = function(){
     var self = this:

     self.Param = new model();
     self.SendData = function(){
	var param = ko.toJS(self.Param);
            url: "controller/CreateData",
            type: "POST",
            contentType: "application/json; charset=utf-8",
            data: ko.utils.stringifyJson(param),
            success: function (result) {
                //success process in here...

Create a viewmodel class:

public class DataViewModel{
    public string FirstName{get;set;}
    public string LastName{get;set;}

And in your controller

public ActionResult CreateData(DateViewModel param) {
	//process here..

Now you can get the data from args param and use that for your transactions.

Happy Coding
