mvc partial view code example

Example 1: asp net core mvc partial view

<partial name="_PartialName" />

Example 2: c# mvc return partial view

// Create a container for your data
<div id="ViewHolder"><div>

//You can call your method using ajax:
$.ajax({
	type: "POST",
	url: '<Your path to your controller>/GetView',
	contentType: "application/text; charset=utf-8",
	dataType: "text",
	async: false,
	success: function (data) {
		// Populate your container
		$('ViewHolder').html(data);
	}
})

// In your controller 
public PartialViewResult GetView()
{
	//Passing a model is optional
  	MyModel myModel = new MyMyodel();
	return PartialView("<Your View Name>", myModel);
}

Example 3: mvc asp.net partial view from js

//You can call a Partial View through AJAX

<div id="containerId"></div>

$.ajax({
    type: "Get",
    url: '<Your url>/GetView',
    data: mydata,
    contentType: "application/text; charset=utf-8",
    dataType: "text",
    success: function (data, status) {
      	//Use append to add it to the div and not overwrite it 
		//if you have other data in your container
        $('#containerId').append(data);
    },
    error: function (err) {
        console.log(err);
    }
});

//In C#

/// <summary>
/// Renders a single view.
/// NOTE : PARTIAL VIEW CANNOT RENDER MULTIPLE VIEWS!
/// Instead loop through them.
/// </summary>
/// <param name="obj">JSON object containing input data</param>
/// <returns></returns>
[HttpGet]
public ActionResult GetView(string obj)
{
    //Parse the object into a model
    try
    {
        MyModel model = (new JavaScriptSerializer()).Deserialize<MyModel>(obj);
        return View("<Your View name>", obj);

    }
    catch (Exception ex)
    {
        return Json(ex.Message, JsonRequestBehavior.AllowGet);
    }

}

Example 4: partial MVC

<partial name="ThenName" model="object" />

Example 5: mvc view vs partial view

I think the biggest difference is about the use of the _Layout page:

PartialView(): the razor engine will get the view (e.g. index.cshtml) without any layout page (_layout.cshtml).
View(): the engine will get your view (e.g. index.cshtml) and then appends the content of this view inside the layout page (_layout.cshtml)
