如何在cshtml视图中使用WebGrid？

Question

我可以在任何控制器中使用WebGrid,例如:

var grid = new WebGrid(emailsFetched, columnNames);

我必须在我的ASP.NET MVC项目中添加一个引用System.Web.Helpers.

但是当我尝试直接在视图中使用这个网格时(为了避免控制器中的实例化和其他设置),它说:The type or namespace 'WebGrid' cannot be found.好的,我也尝试在这里添加一个引用:

@using System.Web.Helpers 但这引发了另一个问题:

There is no build provider registered for the extension '.cshtml'. You can register one in the <compilation><buildProviders> section in the machine.config or web.config. Make sure is has a BuildProviderAppliesToAttribute attribute which includes the value 'Web' or 'All'.

这很奇怪......我在网上看到了足够的例子,它们正在使用WebGrid并且不必在cshtml视图中声明任何内容......

你能告诉我怎么解决这个问题吗？或者为什么我遇到这个非常丑陋的问题？

Answer 1

最后我已经注意到了这一点:

<assemblies> <add assembly="System.Web.Helpers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> </assemblies>

必须添加到web配置,system.web部分下,带有compilation标签,所以它看起来像:

<system.web>
    <compilation debug="true" targetFramework="4.0">
        <assemblies>
            <add assembly="System.Web.Helpers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
        </assemblies>
    </compilation>
</system.web>

尝试按照以前在ASP.NET MVC4项目中测试过的步骤没有任何问题.

1)打开NuGet Package Manager在Visual Studio与搜索"微软网络助手"安装.

2)安装它打开后,web.config在您的解决方案和变化connectionStringName的参数DefaultMembershipProvider,DefaultRoleProvider已经DefaultSessionProvider(如果你不这样做,你可能会遇到"DefaultConnection"没有在应用程序的配置中发现或连接字符串是空的."的错误.

3)重建您的项目,然后在剃刀视图中使用如下所示的smilar定义.

注意:根据您的项目更改"标题","控制器"和"操作"名称Html.ActionLinks.

视图:

@{
var grid = new System.Web.Helpers.WebGrid(
    source: Model,
    columnNames: new List<string>() { "Title" },
    ajaxUpdateContainerId: "myGrid",
    defaultSort: "Name",
    canPage: true,
    canSort: true,
    rowsPerPage: 5
    );
grid.SortDirection = SortDirection.Ascending;
}


@grid.GetHtml(
      tableStyle: "table", /*your class name for this property*/
      headerStyle: "webgrid-header",/*your class name for this property*/
      footerStyle: "webgrid-footer", /*your class name for this property*/
      rowStyle: "webgrid-row-style", /*your class name for this property*/
      alternatingRowStyle: "webgrid-alternating-row",/*your class name...*/                                         selectedRowStyle: "webgrid-selected-row",/*your class name for this property*/

      firstText: "<<",
      lastText: ">>",
      mode: WebGridPagerModes.All,
      fillEmptyRows: true,

      columns: grid.Columns(
       grid.Column("ApplicantID", "No", style: "span1", canSort: true),
       grid.Column("Name", "Name", style: "span2", canSort: true),
       grid.Column("Surname", "Surname", style: "span2", canSort: true),
       grid.Column("Organization", "Org.", style: "span2", canSort: true),
       grid.Column("MeetingId", "Meeting", style: "span1", canSort: true),
        //some format usage samples:
        //grid.Column("Email", "e-mail", style: "span1", canSort: true, format: @<a href="mailto:@item.Email">@item.Email</a>),  
        //grid.Column("BirthDate", format: p=>p.BirthDate.ToShortDateString()),

//for using multiple Html.ActionLink in a column using Webgrid
grid.Column("Operations", format: (item) =>
 new HtmlString(
       Html.ActionLink("Show Details", "Edit", "Admin", new
       {
           applicantId = item.ApplicantID,               
           title = "Detail",
           @class = "icon-link",
           style = "background-image: url('../../Content/icons/detail.png')"
       }, null).ToString() +
       Html.ActionLink("Edit Record", "Edit", "Admin", new
       {
           applicantId = item.ApplicantID, 
           title = "Edit",
           @class = "icon-link",
           style = "background-image: url('../../Content/icons/edit.png')"
       }, null).ToString() +
       Html.ActionLink("Delete Record", "Edit", "Admin", new
       {
           applicantId = item.ApplicantID,
           title = "Delete",
           @class = "icon-link",
           style = "background-image: url('../../Content/icons/delete.png')"
       }, null).ToString()
 )
)
),
numericLinksCount: 5
)

以下是以下css类别Razor.如果您想使用您的css定义,只需将样式属性更改为您的属性(某些属性是可选的,如下所示Razor View).

<style type="text/css">    
    .webgrid-operations { /*for limiting the width of Operations 
                          menu used in the WebGrid*/
    width: 65px;
}

.webgrid-header td {
    text-align: left;
}

.webgrid-header th {
    background-color: #EFEFEF;
    margin-bottom: 2px;
}

.webgrid td {
    padding-right: 15px;
}

.webgrid-footer td {
    font-family: 'open_sanssemibold', sans-serif;

    }

        .webgrid-footer td a:hover {

        }

.webgrid a {
    color: #fff;

.colRowButton {
    width: 70px;
    text-align: left;
}

.webgrid-row-style {
    /*border-bottom: 1px solid #E8EEF4;*/
}

.webgrid-alternating-row td {
    /*background-color: #f9f9f9;*/
}

.webgrid-selected-row {
    /*font-weight: bold;*/
}    

<style type="text/css">

        border: none;
        cursor: pointer;

        height: 16px;
        margin-right: 8px; 
        vertical-align: middle;
    }

    .span5 {
    width:380px
    }
    .span4 {
    width:300px
    }
    .span3 {
    width:220px
    }
    .span2 {
    width:140px
    }
    .span1 {
    width:60px

希望这可以帮助...
