The difference between Partialview and editorfor and displayfor in ASP.

In the same place:

Partialview, Editorfor, and displayfor can all be used to implement the public part of the page, and other pages can be referenced according to the requirements.

The difference:

Partialview is handled from the point of view of the page , so the main page and Partialview generally use the same model, which enables editing of the corresponding fields in the Partialview If Partialview is using the model's sub-model in the main page, then only the display of the model for the partial view can be implemented.

Specific references are: @Html. Partial ("~/views/shared/_productpartial.cshtml")

Editorfor and Displayfor are from the model angle to deal with, at this time Displayfor implementation is the sub-model of the display function, editorfor to achieve the sub-model editing function.

The specific citation is: @Html. editorfor (M = m.products) @Html. displayfor (M = m.products)

Here's a simple example to illustrate

1): Engineering code structure

2): Model structure

     Public classOrdermodel { Public stringOrderId {Get;Set; }  Public stringOrdername {Get;Set; }  PublicList<productmodel> Products {Get;Set; } }     Public classProductModel { Public stringProductId {Get;Set; }  Public stringProductName {Get;Set; }  Public DoublePrice {Get;Set; } }

3): Partialview

3.1): Action Index

         Public actionresult Index ()        {            = getmyorder ();             return View (MyOrder);        }        [HttpPost]          Public ActionResult Index (Ordermodel model)        {            = getmyorder ();             return View (MyOrder);        }

3.2): index.cshtml

@model mvcapplication2.models.ordermodel@{viewbag.title = "Index";} @using (Html.BeginForm ()) {@Html. AntiForgeryToken () @Html. ValidationSummary (True)<Div>        <label>Ordername:</label>@Html. textboxfor (M = m.ordername)</Div>    <Div>@Html. Partial ("~/views/shared/_productpartial.cshtml")</Div>        <inputtype= "Submit"value= "Order" />}

3.3): _productpartial.cshtml

@model MvcApplication2.Models.OrderModel<Div>@foreach (var item in model.products) {<Div>            <label>ProductName:</label>            <inputvalue= "@item. ProductName " />        </Div>                <Div>            <label>Price:</label>            <inputvalue= "@item. Price " />        </Div>    }</Div>

3.4): Run result

4): Editorfor

4.1): Action indexforeditor

         Public actionresult indexforeditor ()        {            = getmyorder ();             return View (MyOrder);        }        [HttpPost]          Public ActionResult Indexforeditor (Ordermodel model)        {            = getmyorder ();             return View (MyOrder);        }

4.2): indexforeditor.cshtml

@model mvcapplication2.models.ordermodel@{viewbag.title = "Indexforeditor";} @using (Html.BeginForm ()) {@Html. AntiForgeryToken () @Html. ValidationSummary (True)<Div>        <label>Ordername:</label>@Html. textboxfor (M = m.ordername)</Div>    <Div>@Html. editorfor (M = m.products)</Div>        <inputtype= "Submit"value= "Order" />}

4.3): productmodel.cshtml

@model MvcApplication2.Models.ProductModel < Div >     @Html. labelfor (M = m.productname)    @Html. textboxfor (M = m.productname)</  div><Div>    @Html. labelfor (M = m.price)    @Html. textboxfor (M = m.price) </ Div >

4.4): Run result

5): Displayfor

5.1): Action indexfordisplay

         Public actionresult Indexfordisplay ()        {            = getmyorder ();             return View (MyOrder);        }        [HttpPost]          Public ActionResult Indexfordisplay (Ordermodel model)        {            = getmyorder ();             return View (MyOrder);        }

5.2): indexfordisplay.cshtml

@model mvcapplication2.models.ordermodel@{viewbag.title = "Indexfordisplay";} @using (Html.BeginForm ()) {@Html. AntiForgeryToken () @Html. ValidationSummary (True)<Div>        <label>Ordername:</label>@Html. textboxfor (M = m.ordername)</Div>    <Div>@Html. displayfor (M = m.products)</Div>        <inputtype= "Submit"value= "Order" />}

@model MvcApplication2.Models.ProductModel < Div >     @Html. labelfor (M = m.productname)    @Html. displaytextfor (M = m.productname)</ Div > < Div >     @Html. labelfor (M = m.price)    @Html. displaytextfor (M = m.price)</  div>

5.4): Run result

6): Public method

        PrivateOrdermodel Getmyorder () {Ordermodel order=NewOrdermodel (); Order. OrderId="o001"; Order. Ordername="Order001"; List<ProductModel> productlist =NewList<productmodel>(); ProductModel product001=NewProductModel (); product001. ProductId="P001"; product001.
