asp.net-mvc – 有条件地在webgrid中显示图像 – mvc 3

在我的网格网格中,我需要根据值显示图像.代码如下

@model TraktorumMVC.Models.ManagePhotos
@{
    ViewBag.Title = "ManagePhotos";
    Layout = "~/Views/Shared/_Layout.cshtml";
    var grid = new WebGrid(Model.AdPhotos);
}


    @grid.GetHtml(
       displayHeader: false,columns: grid.Columns(
             grid.Column(format: (item) =>
                 {
                     if (item.IsMainPreview == true)
                     {
                         return @<text><img src="@Url.Content("~/Content/images/preview-photo.gif")" alt="Image "/></text>;
                     }
                     else
                     {
                         return @<text><img src="@Url.Content("~/Content/images/non-preview-photo.gif")" alt="Image "/></text>;
                     }
                 }
                ),grid.Column(format: (item) => Html.ActionLink("Remove Photo","RemovePhoto","Images",new { photoID = @item.Id },new { @class = "RemovePhoto" }))
         ));

我不知道如果在webgrid我如何使用.我刚刚尝试,它不工作.getting以下错误

The best overloaded method match for 'System.Web.Helpers.WebGrid.Column(string,string,System.Func<dynamic,object>,bool)' has some invalid arguments

解决方法

@grid.GetHtml(
    displayHeader: false,columns: grid.Columns(
            grid.Column(format: (item) =>
                {
                    if (item.IsMainPreview == true)
                    {
                        return Html.Raw(string.Format("<text><img src="{0}" alt="Image"/></text>",Url.Content("~/Content/images/preview-photo.gif")));
                    }
                    else
                    {
                        return Html.Raw(string.Format("<text><img src="{0}" alt="Image"/></text>",Url.Content("~/Content/images/non-preview-photo.gif")));                         
                    }
                }
            ),new { photoID = item.Id },new { @class = "RemovePhoto" }))
        ));

同样在最后一行,而不是新的{photoID = @ item.Id},您应该写新的{photoID = item.Id}
