使用 System.Web.Helpers.WebGrid
我正在尝试使用 WebGrid 在我的模型中显示数据，但遇到了大量问题。我的模型包含以下内容：
public IEnumerable<Auction> Auctions { get; set; }
我所做的是：
@{
var grid = new WebGrid(Model.Auctions, rowsPerPage: Model.PagingInfo.ItemsPerPage, defaultSort: "Title", canPage: true, canSort: true)
{SortDirection = SortDirection.Ascending};
grid.Pager(WebGridPagerModes.NextPrevious);
}
我想根据当前行中的拍卖类型在第一列中显示一些文本，因此我在模型中编写了一个方法：
public string GetAuctionType(Auction auction)
{
var type = string.Empty;
if (auction is LubAuction)
{
type = "Lowest unique wins";
}
else if (auction is EsfAuction)
{
type = "Highest wins";
}
return type;
}
现在，我的视图还包含：
@grid.GetHtml(
columns: grid.Columns(
grid.Column("OwnerReference", header: "Owner reference")
)
);
问题是如何在上面添加 grid.Columns 行以显示 GetAuctionType 中的文本？
另外，另一个问题是没有出现寻呼机并且排序不起作用。
我将不胜感激所有的帮助。
谢谢，

I'm trying to use a WebGrid to display data in my model and am having a huge number of issues. My model contains among other things this:
public IEnumerable<Auction> Auctions { get; set; }
What I have done is:
@{
var grid = new WebGrid(Model.Auctions, rowsPerPage: Model.PagingInfo.ItemsPerPage, defaultSort: "Title", canPage: true, canSort: true)
{SortDirection = SortDirection.Ascending};
grid.Pager(WebGridPagerModes.NextPrevious);
}
I want to display some text in the first column depending on the type of the auction in the current row, so I have written a method in the model:
public string GetAuctionType(Auction auction)
{
var type = string.Empty;
if (auction is LubAuction)
{
type = "Lowest unique wins";
}
else if (auction is EsfAuction)
{
type = "Highest wins";
}
return type;
}
Now, my view also contains:
@grid.GetHtml(
columns: grid.Columns(
grid.Column("OwnerReference", header: "Owner reference")
)
);
Question is how do I add a grid.Columns line in the above to display the text in GetAuctionType?
Also, the other issue is that there is no pager appearing and sorting does not work.
I would appreciate all help.
Thanks,
Sachin

我会将 GetAuctionType 逻辑移至部分类，以便您可以像集合中每个对象的普通属性一样访问它。您可能还想看看问题 ASP.NET MVC3 WebGrid 格式：参数 涵盖了 WebGrid 列格式语法的用法。
关于您的其他问题，您在 javascript 控制台中看到任何错误吗？
I would move GetAuctionType logic to a Partial Class so you can access it like a normal property on each object in your collection. You may also want to take a look at question ASP.NET MVC3 WebGrid format: parameter that is covering usage of WebGrid's column format syntax.
Regarding your other issues, do you see any errors in javascript console ?
