mvc example for displaying or Showing dates using DayCalendarPage extension method

Description:-

            In this example we explain that how to create a event dates in List format with event title and event description in mvc4.

In my events web site I need to show event dates in lists format so users can easily see them and understand it.. As there are more than one view where I need this functionality I wrote HTML extension method that outputs day calendar view based on current date. In this posting I will show you my extension method and show you how to use it.

DayCalendarPage extension method

Here is the extension method that generates day calendar page like shown above.

---

public static MvcHtmlString DayCalendarPage(this HtmlHelper helper, DateTime date)
{
    var buffer = new StringBuilder();
    buffer.Append(@"<div class=""dayCalendarPage"">");

    buffer.Append(@"    <div class=""title"">");
    buffer.Append(date.ToString("MMM"));
    buffer.Append(@"    </div>");

    buffer.Append(@"    <div class=""day"">");
    buffer.Append(date.ToString("dd"));
    buffer.Append(@"    </div>");

    buffer.Append(@"</div>");

    return MvcHtmlString.Create(buffer.ToString());
}

---

This method outputs HTML that is made to nice day calendar page using CSS.

CSS

Here is my CSS that makes calendar look nice. It is not very optimal I think but it works.

---

/* DAY CALENDAR PAGE */ 
.dayCalendarPage
{
     clear:none;
     float:left;
     text-align:center; 
     border:1px solid lightgrey; 
     margin-right:10px;
}
.dayCalendarPage .title
{
     background-color:Red;
     color:White;
     width:50px;    
}
.dayCalendarPage .day
{
     font-size:15pt;
     font-weight:bold;
     padding-top: 5px;
     padding-bottom: 5px;
}

---

Now as you have extension method and styles added to your project it is time to use them.

How to redirect to another page from MVC controller in mvc4

Description:-

            In Previous Example We Explain that How to Export Gridview or Webgrid Data to MS Word or MS Excel sheet in MVC4.but now in this example we explain that how to redirect one page to another page in mvc or redirect from Controller to view page in mvc.

This is simple just you can pass the url in controller method and in which we create a code to redirect to the specified URL argument like

<form action="/Home/Goto" method="post">

    <label for="gotourl">url:</label>

    <input type="text" name="gotourl" />

    <input type="submit" />

    </form>

In above code you enter the url of the page that you want to redirect and when click on submit button then it will call the Goto method of the Homecontroller like

public ActionResult Goto(string gotourl)

        {

         

            return Redirect(gotourl);

        }

Look at this method simple redirect the page with  gotourl argument that you can enter in the Textbox.

The main thing keep in mind is that  <input type="text" name="gotourl" /> name of textbox and argument of method both are same like name of textbox gotourl and argument of the method like public ActionResult Goto(string gotourl) must be same that you are define in controller method.

   DataClasses1DataContext dc = new DataClasses1DataContext();

        public ActionResult Index()

        {

            var lst = (from p in dc.movies select p).ToList();

            return View(lst);

        }

Load UserControl Dynamically using Jquery Ajax in Asp.Net without Postback

Description:-

            In previous example we allready expalin that how to perform Insert,Update,Delete in Gridview without Postback using Jquery/Ajax.but now in this example we explain how to Load Asp.Net usercontrol(.ascx control) in aspx webpage without Postback using Jquery Ajax in asp.net.we can also Load the css or javascript that are define in usercontrol.

What is UserControl

.Net provide a  Web server controls by using this in your ASP.NET Web pages, you can easily create our own custom, reusable controls using the same techniques as you use for creating ASP.NET Web pages and these controls are known as user controls.

A user control is a kind of composite control that works much like an ASP.NET Web page andYou can easily embed them in ASP.NET Web pages in which they act as a unit.
 

This is very useful example when that type of problem you faced like

For Example:-

I have a ASP.Net(C#) page. When a user selects a value in dropdownlist, some new controls will be visible to him. I am able to that now, but the page has to reload every time and state has to be maintained between postbacks.

So in this sitution you can easily Load the control without Postback or PageLoad.

Insert, Update, Delete in DetailsView in ASP.NET

DetailsView control in ASP.NET is used to display the Details of the master record in a table format or single record at a time. You can easily insert, update, delete and paging to data items in DetailsView. In this example we explain that how to perform Insert,Update,Delete Operation in Detailview in Asp.Net.

The idea behind using the DetailsView control is nothing but displaying the Details of the master. By default, the DetailsView control displays each field of a record on its own line. The DetailsView control displays only a single data record at a time, even if its data source contain more than one records.

The DetailsView control is typically used for display the detail of master record in a master/detail scenario where the selected record of the master control determines the record to display in the DetailsView control. The DetailsView control does not support sorting but it supports paging.

there are three modes of the Detailsview are as follows:

DetailsViewMode.Edit :-the Detailview is in Editmode and allows user to edit and update record.

DetailsViewMode.Insert :- the Detailview is in Insertmode and allows user to insert the new record.

DetailsViewMode.ReadOnly : the Detailview is in readonly mode and is the normal display mode of Detailview

Handling multiple submit buttons on the same form in MVC

sometimes you faced sitution like more than one submit buttons on the same form in mvc razor. At that time, how we  will handle the click event of each and every buttons on your form?

To overcome this problem  I am going to explain the various techniques for handling multiple buttons on the same form in MVC. Suppose you have a user Login form like as below:

In the above fig. we have Signup,SignIn and cancel buttons. Suppose on Signup button click you have to open Signup window & on SingnIn button click you have to open Login window and on Cancel button click you are returning to home page. For handling all of the above buttons click we have the three methods as mention below:

In this way each submit button will post the form to server but provides the different values Like SighIn, Signup,Cancel and NULL respectively for the commands.so by using this command argument we can easily implement our own logic in the controller's action method.

MVC Example for Display Footer or Grand total in webgrid in mvc4

Description:-

            In previous example we already explain that how to create footer toatal or grand total in Gridview in Asp.Net but now        In this Example we explain that how to Display or maintain footer total or grandtotal in Gridview or webgrid with Paging facility in mvc4.

Here is a code for how to maintain or Display Grantotal or Footer total in Webgrid

<script type="text/javascript">

    $(document).ready(function () {

        var total = 0;

      

        $('#grid .Salary').each(function () {

            total = total + parseFloat($(this)[0].innerHTML.toLocaleString());

          

        });

        $('tbody').append('<tr><td><b>Total</b></td><td><b>' + total.toFixed(2) + '</b></td></tr>');

    });

</script>

Look at this above code we use Jaquery for Append the Footer template in webgrid in which function it will read webgrid row one by one and calculate the total of the all rows and finally append to the webgrid as a Footer.

to do this you have to first create the table like below with name poll and create Linqtosql dataclasses in Model folder and drag and drop this table.

in this example we provide facility to user just browse the Excelsheet database file and click on export button then all data of the Excel Sheet File will be Automatically saved to the Sqlserver Database.

To do this First create the table with same coloumn name as we define in our Excel Sheet File like
