Asp.net mvc razor render partial view using ajax helper

This is the extension to my blog in which I demonstrated rendering of the partial view using jquery Ajax . I want to demonstrate here yet another way by which partial view can be rendered without page refresh. Here is the implementation.

Step 1:

I will again be using DisplayData class in my demo. Here is it.

  
    public class DisplayData
    {
       public int ID { get; set; }
       public DisplayData(int ID)
       {
              this.ID = ID;
       }
    }

Step 2:

Create a PartialDemo page

@model IEnumerable<MvcApplication5.Models.DisplayData>
@{
    ViewBag.Title = "PartialDemo";
}


@Ajax.ActionLink("Click 1", "PartialDemo", "PartialDemo", new {Data= "1" }, new AjaxOptions { UpdateTargetId = "rsvpmsg" })
@Ajax.ActionLink("Click 2", "PartialDemo", "PartialDemo", new {Data= "2" }, new  AjaxOptions { UpdateTargetId = "rsvpmsg" })

<div id="rsvpmsg">
@{ Html.RenderPartial("PartialDemoUC", this.Model);}
</div>


Step 3:

Create a User Control PartialDemoUC.cshtml

@model IEnumerable<dynamic>

@foreach(var items in Model)
{
   @items.ID    
}


Step 4:

In a PartialDemo controller create an Action method for rendering the partial view on the first call to the method and then on an ajax call(on the click of the link)

  
    public ActionResult PartialDemo(string Data)
    {
       List<DisplayData> Display = new List<DisplayData>();

       if (Request.IsAjaxRequest())
       {
          if (Data == "1")
          {
             Display.Add(new DisplayData(3));
             Display.Add(new DisplayData(4));
          }
          else
          {
            Display.Add(new DisplayData(5));
            Display.Add(new DisplayData(6));
          }
          return PartialView("PartialDemoUC",Display);
       }
       else
       {
           Display.Add(new DisplayData(1));
           Display.Add(new DisplayData(2));
           return View("PartialDemo", Display);
       }
    }

  1. Many examples like this on the internet are too complicated to follow without their whole project.
    This was simple and easy to follow from scratch.
    Great work, thanks.

Asp.net mvc razor render partial view using jquery Ajax

I will going to demonstrate how we can render PartialViews using Jquery Ajax. I will be clicking an a href link ,then I will be calling the controller through jquery Ajax which will fill the partialview for a really nice user experience. Step 1: First of all we will be creating an DisplayData class for the use for this example in the model. public class DisplayData { public int ID { get; set; } public DisplayData(int ID) { this.ID = ID; } } Step 2: We will create a Clicks page and write the following code on it. Specially note empty here which will going to empty and then fill partialview with new records. $(document).ready(function () { $('.msg').click(function () { var id = this.id; $.ajax({ url: "/Category/Display", data: { data: id }, success: function (mydata) { $("#link").empty().appe

Asp.net mvc DataAnnotation ValidateAttribute two properties comparison.

Using Datannotion is great but there are scenarious in which the current attributes compare, range etc becomes inadequate especially for the comparisions. So we create here our own custom validation using ValidationAttribute class which is the base class for all the annotation attributes. So by deriving from it and overriding the Isvalid method we can create our custom attribute for the model. So here is the scenario in which I will be validating the Username against the password which should not be equal. Compare attribute cannot be used in this scenario so I have created a custom attribute for that. Here is the model with the attribute. User View Model [CompareUserPass("UserName", "Password", ErrorMessage = "UserName and password cannot be equal")] public class UserView { [Required(ErrorMessage = "UserName Required")] public string UserName { get; set; } [Required(
