MonoDevelop Cross Platform Using Csharp


MonoDevelop is a revolution in the era of Cross development by using Microsoft .NET programming language like Csharp ( C# ) , Visual Basic and Jsharp ( J# ) . Monodevelop has removed blame that Microsoft .NET software can only run on Windows platforms This makes possible to run .net applications and to build a .Net Application on any platform

MonoDevelop is a cross-platform IDE  developed for Csharp ( C# ) programming language  and other .NET programming languages. MonoDevelop allows programmers to program desktop softwares and ASP.NET Web applications and websites  on Linux, Windows  and Mac OSX. MonoDevelop  makes possible for .net programmers to run , create and deploy their .net software applications on cross-platforms Any  .NET application developed  with Visual Studio can be used in linux or Mac with the help of MonoDevelop

Windows platform is fully supported  for running MonoDevelop and it is fully accepted. In past there were many issues regarding Mono Development but now  Many Windows specific issues have been fixed, and ome add-ins such as debugging and subversion support have been written specifically for Windows and it is fully supported by windows

By developing with mono specifically, you will be able to run your executable on any platform that has mono available for it. That in and of itself is mono's biggest advantage over developing on MSFT's .Net platform. Said differently: If you build you assembly with mono, you're guarantee cross-platform support

Features Of MonoDevelop


  1. Multi-platform support

    It Supports Linux ( ubuntu etc ) , Windows( xp,7,8 etc ) and Mac OS X operating systems
  2. Advanced Text Editing Facilities

    It provides Code completion support for Csharp  4 that is lastest version for csharp

    4. Then parameters are passed to query dynamically using following line of code
      cmd.Parameters.Addwithvalue('parametername' , 'value' );
    5. Then we have used MySqlDataAdapter that act as a pipeline between database and csharp app . It takes or select query from csharp application and then make interface or link to database and execute the query in database and get result returned by query executed in database
    6. Then it fill the returned result in placeholder called DataTable that saves data returned from or retrieved from database into tabulated form
    7. Now if (dt.Rows.Count >0) checks if dt contains some item then put the data in respective text fields

    sql insert , Update , delete using c#


    To connect Database from your Windows Application is required  to make Application for querying the database and retrieve the desired result from database . Database in widely used in management software's  and various applications to save record and search the record .

    Database dependent applications are widely used in the market . ERP projects of organisation are highly Database dependent applications . The main two types of databa se that are widely used in .NET Applications :-

    * Microsoft Access Database
    * MSSQL Server ( Microsoft Structured Query Language )


    The main Languages used in .NET Platform for connecting windows application to database are :-

    * C#
    * VB#

    Sql ( Structured Query Language ) is most widely used Database . It is free and Opensource Database . It has simple query structure to Manipulate data from database in Database applications 

    To Learn About SQL and how to learn SQL you can go to following links first then go forward :-

    SQL Tutorial with Examples and snapshots

    insert , update , delete , select queries sql

    Download Database Script file and execute it in your SQL Server

    Steps To Execute this Script file -

    1. Download Script file from link below .

    2. Now open it with MsSql .
    3. Now Create Database Named  'Accounts_database' in MsSql server 
    4. Now select this database from Dropdown 
    5. And Execute the Script code by clicking F5 .

    Design of Form 

    Download Complete Project File


    1. In Design We have some Fields to be filled to insert Data To database

    2. We are having 3 Buttons - One for Update and Insert Operation , Second For Delete Operation and Third for Exit or close form

    3. We are using Datagrid View to Instantly Showing The data in database and it is updated when we insert new data to database or we delete data from database

                                                       Insertion/Updation In Database 


    1. For insertion of data Fill the fields on form Only Code and Agency Name is required and rest of the fields are optional fields


    2. Now you can see filled data is successfully inserted and it is immediately shown in below datagridview


    CODE For Insert/Update

     {
                    SqlCommand cmd1 = new SqlCommand("select * from Agency_detail where  Agency_code=" + textBox1.Text, con);
                    SqlDataAdapter da1 = new SqlDataAdapter();
                    DataTable dt1 = new DataTable();
                    da1.SelectCommand = cmd1;
                    da1.Fill(dt1);
                    if ((dt1.Rows.Count > 0) && (dt1.Rows[0][0].ToString() != ""))
                    {
                        if (MessageBox.Show("ID Already Exist Do you want to Update It", "Confirm", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)
                        {
                            SqlCommand cmdupdate = new SqlCommand("update Agency_detail set Agency_Name=@p1,Phone=@p2,fax=@p3,Mobile_Number=@p4,DOJ=@p5,opening=@p6,Remark=@p7,Address=@p8,city=@p9,state=@p10,zip_code=@p11,email=@p12 where Agency_code=" + textBox1.Text, this.con );
                            cmdupdate.Parameters.AddWithValue("@p1", textBox2.Text);
                            cmdupdate.Parameters.AddWithValue("@p2", textBox4.Text);

    Implementing Search Functionality in ASP.NET MVC 4

    What we are Going To cover


    * In this Tutrial we are going to cover how to implement search functionality in Asp.Net MVC 4 . In our web applications in MVC we often need to add the functionality to search the database objects for specific data based on some creteria like to find employees with name starting with 'N' or to find data of employees that have Gender Male

    Download Demo App With Database Link Below

    Creating Database For This Application

    1. First create Database

    * Open Microsoft Sql server . Click on New Query . Now execute the query below to create database

    Create Database searchingInmvc

    2. Then Press F5 . This will create Database successfully

    Create Table And Inserting Demo Data


    create table tblEmployee         //creating table
    (
    ID int identity primary key,
    Name nvarchar(50),
    Gender nvarchar(50),
    Email nvarchar(50)
    )
    Implementing Search Functionality in ASP.NET MVC 4
    Creating Table In database 

    //Inserting Demo Data

    Here , we are inserting 4  Rows in Database table

    insert into tblEmployee values('John','Female','john@geeksprogrammings.blogspot.in')
    insert into tblEmployee values('funky','Male','funky@geeksprogrammings.blogspot.in')
    insert into tblEmployee values('wiley','Male','wiley@geeksprogrammings.blogspot.in')
    insert into tblEmployee values('ceren','Female','ceren@geeksprogrammings.blogspot.in')

    Implementing Search Functionality in ASP.NET MVC 4
    Inserting Data in Table 

    Showing All Inserted Data

    Download Database script file

    In link below you can download the script file and then double click on file it will open in sql server . It will create the database automatically for you when you execute it

    Create New MVC 4 Application in Visual Studio

    1. Start Visual Studio with language selected as C#
    2.Click on File --> Then click on New Project
    3. Scroll down and select ASP.NET MVC 4 Web Application

    4. Give appropriate Name,Path and solution Name and Hit Enter
    5. choose Empty Template
    6. Choose Razor View Engine and Hit Enter
    7. Now New MVC 4 web application is started

    Adding Models to MVC 4 Application

    1. In solution Explorer -- > Right click on Models --> Then click on New item

    Implementing Search Functionality in ASP.NET MVC 4

    2. Then select ADO.NET Entity Data Model --.> Give it a valid name like 'sampledatamodel'
    3. Click Add

    9. Now Model is successfully Added

    Adding Controller and Views To MVC 4 Application

    To add controller to database --

    1. Right click on Controllers folder in solution folder
    2. click on Add --> Then click on Controller

    3. Now Add controller Dialog Box appears
    4. Give your controller a name like 'HomeController'
    5. In template choose  'MVC controller with read/write and views using Entity  Framework'
    6. The Reason behind choosing this is it will automatically generate some pages to insert,delete , update data of model to which we are associating this controller
    7. Now give the Model name that we have added in previous step 'Employee'
    8. Now Choose dbcontext class from dropdown menu and finally  click ADD
    9. This autimatically add Views for insert , update, delete and index view in views folder under controller named folder

    Adding Style And Look To Application

    So we are going to search the database and retrieve data from database and then show the retrieved result to user. For this we have to get some controls and code . The GUI design that are going to give to this application is as below :-

    1. In solution Explorer under Index view Double click on Index.cshtml
    2. Now just before the line '<h2>Index</h2>' add a line 

    <div style='font-family:Arial'>
    and close this div right below the code after table tag 

    Other UpdationAre in Demo Project Downlao And Use it

    3. Update your Index.cshtml file under view folder in solution Explorer with the code below

    @model IEnumerable<SearchInMVC.Models.Employee>
    @{
        ViewBag.Title = "Index";
    }
    <div style="font-family:Arial ">
    <h2>Index</h2>

    <p>
        @Html.ActionLink("Create New", "Create")
    </p>
    <p>
    @using (Html.BeginForm ("Index","Home",FormMethod.Get ))
    {
    <b>Search by:</b>@Html.RadioButton("searchBy","Name")<text> Name</text>
    @Html.RadioButton("searchBy","Gender")<text>Gender</text><br />
    @Html.TextBox("Search");<input type="submit" value="Search" />
        }
    </p>
    <table border="1">
        <tr>
            <th>
                @Html.DisplayNameFor(model => model.Name)
            </th>
            <th>
                @Html.DisplayNameFor(model => model.Gender)
            </th>
            <th>
                @Html.DisplayNameFor(model => model.Email)
            </th>
            <th>Action</th>
        </tr>
        @if (Model.Count() == 0)
        {
            <tr>
            <td colspan ="4">No Rows Match Search Criteria</td>
            
            </tr>
        }
        else
        {
    foreach (var item in Model)
    {
        <tr>
            <td>
                @Html.DisplayFor(modelItem => item.Name)
            </td>
            <td>
                @Html.DisplayFor(modelItem => item.Gender)
            </td>
            <td>
                @Html.DisplayFor(modelItem => item.Email)
            </td>
            <td>
                @Html.ActionLink("Edit", "Edit", new { id = item.ID }) |
                @Html.ActionLink("Details", "Details", new { id = item.ID }) |
                @Html.ActionLink("Delete", "Delete", new { id = item.ID })
            </td>
        </tr>
    }
        }
    </table>
    </div>




    Now Run your Application and you can see the change with output below :-

    Implementing Search Functionality in ASP.NET MVC 4
    Implementing Search Functionality in Asp.Net MVC 4

    Code Description

    In code above we have used Razor code and instead of using <form> tag that we usually use in html we have used Html Helper below


    @using (Html.BeginForm ("Index","Home",FormMethod.Get ))
    {
    <b>Search by:</b>@Html.RadioButton("searchBy","Name")<text> Name</text>
    @Html.RadioButton("searchBy","Gender")<text>Gender</text><br />
    @Html.TextBox("Search");<input type="submit" value="Search" />
        }




    In Html.BeginForm ("Index","Home",FormMethod.Get )

    Here, Html.BeginForm  is used in place of using form tag . Html.BeginForm  Received 3 arguments .
    Here, "Index" is Name of action that will be executed on posting form  to server
    Here, "Home" is name of controller to which this link will be redirected when clicked
    Here, " FormMethod.Get" type of encoding method that applied on data we are posting 

    Now Open Controller And Add code below to Index Action of home controller

     if (searchby == "Gender")
                {
                    return View(db.Employees.Where(x => x.Gender == search || search ==null).ToList());
                }
                else
                {
                    return View(db.Employees.Where(x => x.Name.StartsWith(search)).ToList());
    }
