Hinzufügen von Kontrollkästchen zu jeder Zeile in MVCcontrib Grid

Question

Wie kann ich jeder Zeile eines MVCcontrib-Grids ein Kontrollkästchen hinzufügen. Wenn das Formular veröffentlicht ist, finden Sie heraus, welche Datensätze ausgewählt wurden. Ich finde nicht viel, wenn ich danach suche. Danke

Answer 1

hier, wie Sie vorgehen könnte:

Modell:

public class Product 
{ 
    public int Id { get; set; } 
    public string Name { get; set; } 
    public bool IsInStock { get; set; } 
} 

Controller:

public class HomeController : Controller 
{ 
    public ActionResult Index() 
    { 
     var products = new[] 
     { 
      new Product { Id = 1, Name = "product 1", IsInStock = false }, 
      new Product { Id = 2, Name = "product 2", IsInStock = true }, 
      new Product { Id = 3, Name = "product 3", IsInStock = false }, 
      new Product { Id = 4, Name = "product 4", IsInStock = true }, 
     }; 
     return View(products); 
    } 

    [HttpPost] 
    public ActionResult Index(int[] isInStock) 
    { 
     // The isInStock array will contain the ids of selected products 
     // TODO: Process selected products 
     return RedirectToAction("Index"); 
    } 
} 

Ausblick:

<% using (Html.BeginForm()) { %> 
    <%= Html.Grid<Product>(Model) 
      .Columns(column => { 
       column.For(x => x.Id); 
       column.For(x => x.Name); 
       column.For(x => x.IsInStock) 
         .Partial("~/Views/Home/IsInStock.ascx"); 
      }) 
    %> 
    <input type="submit" value="OK" /> 
<% } %> 

Teil:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<MyNamespace.Models.Product>" %> 
<!-- 
    TODO: Handle the checked="checked" attribute based on the IsInStock 
    model property. Ideally write a helper method for this 
--> 
<td><input type="checkbox" name="isInStock" value="<%= Model.Id %>" /></td> 

Und schließlich ist hier ein Hilfsmethode Sie diese Checkbox verwenden könnte zu generieren:

using System.Web.Mvc; 
using Microsoft.Web.Mvc; 

public static class HtmlExtensions 
{ 
    public static MvcHtmlString EditorForIsInStock(this HtmlHelper<Product> htmlHelper) 
    { 
     var tagBuilder = new TagBuilder("input"); 
     tagBuilder.MergeAttribute("type", "checkbox"); 
     tagBuilder.MergeAttribute("name", htmlHelper.NameFor(x => x.IsInStock).ToHtmlString()); 
     if (htmlHelper.ViewData.Model.IsInStock) 
     { 
      tagBuilder.MergeAttribute("checked", "checked"); 
     } 
     return MvcHtmlString.Create(tagBuilder.ToString()); 
    } 
} 

die die teilweise vereinfacht:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<MyNamespace.Models.Product>" %> 
<td><%: Html.EditorForIsInStock() %></td> 

Answer 2

zur Lösung dieses in jeder bekommen Anfrage Ich bin Anhängen des Kontrollkästchens Wert als kommagetrennte Zeichenfolge. Rufen Sie dann die Werte aus der Abfragezeichenfolge ab.

$("#pageLayout a").click(function() { 
     //Check for the click event insed area pageLayout 
     //get the href of link 
     var link = $(this).attr('href'); 
     var apps = ''; 

     //for all the checkbox get the checked status 
     $("input:checkbox").each(
      function() { 
       if ($(this).attr('name') != 'IsChecked') { 
        if (apps != '') { 
         apps = apps + ',' + $(this).attr('name') + '=' + $(this).is(':checked'); 

        } 
        else { 
         apps = $(this).attr('name') + '=' + $(this).is(':checked'); 
        } 
       } 

      } 
      ) 


     //Used to check if request has came from the paging, filter or sorting. For the filter anchor href doesnt haave 
     //any query string parameter. So for appending the parameter first ? mark is used followed by list of query string 
     //parameters. 
     var index = link.lastIndexOf('?');    

     //If there is no question mark in the string value return is -1 
     if (index == -1) { 
      //url for the filter anchor tag 
      //appList hold the comma sep pair of applicationcode=checked status 
      link = link + '?appList=' + apps + '&profileName=' + $('#ProfileName').val(); 
     } 
     else { 
      //url for sorting and paging anchor tag     
      link = link + '&appList=' + apps + '&profileName=' + $('#ProfileName').val(); 

     } 


     //Alter the url of link 
     $(this).attr('href', link); 


    }); 

Answer 3

weiß nicht, ob das hilft, aber ich habe eine ähnliche Sache unter dem Code:

@Html.Grid(Model.PagedModel).AutoGenerateColumns().Columns(column => { 
column.For(a => Html.ActionLink("Edit", "Edit", new { a.ID })).InsertAt(0).Encode(false); 
column.Custom(a => Html.Raw("<input type='checkbox' name='resubmit' value='" + a.ID + "'/>")); 
}) 

Mein Controller dann in der Lage war, die ausgewählt Checkboxlist Artikel erhalten:

[HttpPost] 
public ViewResult List(string[] resubmit)

In Ihre Ansicht (z. B. ReportList.cshtml) enthält Ihr Raster in einem Formular und definiert eine Aktion für das Formular

<html> 
<form action="/SubmitReportList"> 
      @{Html.Grid((List<NetSheet.Models.Report>)ViewData["ReportList"]) 
     .Sort((GridSortOptions)ViewData["sort"]) 
     .Attributes(id => "grid", @class => "grid") 

     .Columns(column => 
     { 
      column.For(c => Html.CheckBox("chkSelected", new { @class = "gridCheck", @value = c.ReportId })) 
      .Named("").Encode(false) 
      .Attributes(@class => "grid-column"); 


column.For(c => c.ReportName) 
       .Named("Buyer Close Sheet Name") 
       .SortColumnName("ReportName") 
       .Attributes(@class => "grid-column"); 

     }) 
     .Render();} 

<input type="submit" name=" DeleteReports" id=" DeleteReports" value="Delete" class="btnSubmit"/> 

</form> 
</html> 

Dann in Ihrem Controller Ihre Aktion-Methode

public ActionResult SubmitReportList (string ReportListSubmit, IList<string> chkSelected){ 
    // The IList chkSelected will give you a list of values which includes report ids for the selected reports and “false” for the non-selected reports. You can implement your logic accordingly. 
    return View("ReportList"); 
    }
