html - 在一个页面中无冗余地添加具有样式的多个 WebGrid

Question

基本上，这是我在 View 中的代码，我不想重复 WebGrid 实例。

我的模型

public class UsersWithDetailsModels
{
    public IEnumerable<ApplicationUser> ApplicationUsers { get; set; }
    public IEnumerable<PersonalInfo> PersonalInfos { get; set; }
    public IEnumerable<CreditHistory> CreditHistories { get; set; }
    public IEnumerable<Transaction> Transactions { get; set; }
}

我的 Controller

[AllowAnonymous]
public ActionResult Index(UsersWithDetailsModels model)
{
    return View(model);  // HERE: I can't get any data from database
}

Index.cshtml

@model IEnumerable<Lml.Models.UsersWithDetailsModels>

@{
    ViewBag.Title = "Home";
    Layout = null;

    // TABLE 1 with pager
    var pg = new WebGrid(Model, defaultSort: "Id", canPage: true, ajaxUpdateContainerId: "borrowersAppliedTable");
    pg.Pager(WebGridPagerModes.All);

    // TABLE 2 with pager
    var hg = new WebGrid(Model, defaultSort: "Id", canPage: true, ajaxUpdateContainerId: "borrowersAppliedAddressTable");
    hg.Pager(WebGridPagerModes.All);

    // TABLE 3 with pager
    var hg = new WebGrid(Model, defaultSort: "Id", canPage: true, ajaxUpdateContainerId: "borrowersAppliedMailingTable");
    hg.Pager(WebGridPagerModes.All);
}

你可以明显地看到它是多么的多余。

此外，我这里有列样式

<!-- TABLE 1 -->
<div class="col-lg-6">
    <h2>Borrowers Applied</h2>
    <div class="table-responsive">
        @pg.GetHtml(
            htmlAttributes: new { id = "borrowersAppliedTable" },
            tableStyle: "table table-bordered table-hover table-striped",
            footerStyle: "table-footer text-center",
            columns:
                pg.Columns(
                    pg.Column(columnName: "Id", header: "Entry ID", format: (item) => item.GetSelectLink(item.Id.ToString())),
                    pg.Column(columnName: "DateApplied", header: "Entry Date"),
                    pg.Column(columnName: "FullName", header: "Full Name"),
                    pg.Column(columnName: "Email", header: "Email address")
            )
        )
    </div>
</div>

<!-- TABLE 2 -->
<div class="col-lg-6">
    <h2>Home Addresses</h2>
    <div class="table-responsive">
        @hg.GetHtml(
            htmlAttributes: new { id = "borrowersAppliedAddressTable" },
            tableStyle: "table table-bordered table-hover table-striped",
            footerStyle: "table-footer text-center",
            columns:
                hg.Columns(
                    hg.Column(columnName: "Id", header: "Entry ID", format: (item) => item.GetSelectLink(item.Id.ToString())),
                    hg.Column(columnName: "Street", header: "Street Address"),
                    hg.Column(columnName: "City", header: "City/Municipality"),
                    hg.Column(columnName: "Zip", header: "ZIP Code"),
                    hg.Column(columnName: "State", header: "Province/State"),
                    hg.Column(columnName: "Country")
        )) 
    </div>
</div>

<!-- TABLE 3 -->
<div class="col-lg-6">
    <h2>Mailing Addresses</h2>
    <div class="table-responsive">
        @hg.GetHtml(
            htmlAttributes: new { id = "borrowersAppliedMailingTable" },
            tableStyle: "table table-bordered table-hover table-striped",
            footerStyle: "table-footer text-center",
            columns:
                hg.Columns(
                    hg.Column(columnName: "Id", header: "Entry ID", format: (item) => item.GetSelectLink(item.Id.ToString())),
                    hg.Column(columnName: "MailStreet", header: "Street Address"),
                    hg.Column(columnName: "MailCity", header: "City/Municipality"),
                    hg.Column(columnName: "MailZip", header: "ZIP Code"),
                    hg.Column(columnName: "MailState", header: "Province/State"),
                    hg.Column(columnName: "MailCountry", header: "Country")
            )
        )
    </div>
</div>

正如您所看到的这些行，我想将其应用于每个表。

tableStyle: "table table-bordered table-hover table-striped",
footerStyle: "table-footer text-center",

我不想再重复一遍。

谁能帮我知道在一个页面中显示多个 WebGrid 的快捷方式或有什么简洁的方法吗？

一种选择是为网格创建配置对象并循环遍历它们以生成实际的 html:

@model Lml.Models.UsersWithDetailsModels

@{
    ViewBag.Title = "Home";
    Layout = null;

    var configs = new[]
    {
        new
        {
            Model = (IEnumerable<object>)Model.ApplicationUsers,
            Id = "borrowersAppliedTable",
            Header = "Borrowers Applied",
            Columns = new[]
            {
                new {Name = "UserId", Header = "Entry ID"},
                new {Name = "DateApplied", Header = "Entry Date"},
                new {Name = "FullName", Header = "Full Name"},
                new {Name = "Email", Header = "Email address"}
            }
        },
        new
        {
            Model = (IEnumerable<object>)Model.PersonalInfos,
            Id = "borrowersAppliedAddressTable",
            Header = "Home Addresses",
            Columns = new[]
            {
                new {Name = "Id", Header = "Entry ID"},
                new {Name = "Street", Header = "Street Address"},
                new {Name = "City", Header = "City/Municipality"},
                new {Name = "Zip", Header = "ZIP Code"},
                new {Name = "State", Header = "Province/State"},
                new {Name = "Country", Header = "Country"}
            }
        },
        new
        {
            Model = (IEnumerable<object>)Model.CreditHistories,
            Id = "borrowersAppliedMailingTable",
            Header = "Mailing Addresses",
            Columns = new[]
            {
                new {Name = "Id", Header = "Entry ID"},
                new {Name = "MailStreet", Header = "Street Address"},
                new {Name = "MailCity", Header = "City/Municipality"},
                new {Name = "MailZip", Header = "ZIP Code"},
                new {Name = "MailState", Header = "Province/State"},
                new {Name = "MailCountry", Header = "Country"}
            }
        },
        ...
    };
    var tables = configs.Select(config =>
    {
        var grid = new WebGrid(config.Model, defaultSort: config.Columns[0].Name, canPage: true, ajaxUpdateContainerId: config.Id);
        grid.Pager(WebGridPagerModes.All);

        return new { Id = config.Id, Grid = grid, Header = config.Header, Columns = config.Columns};
    });
}

@{
    foreach (var table in tables)
    {
        <div class="col-lg-6">
            <h2>@table.Header</h2>
            <div class="table-responsive">
                @table.Grid.GetHtml(
                    htmlAttributes: new {id = table.Id },
                    tableStyle: "table table-bordered table-hover table-striped",
                    footerStyle: "table-footer text-center",
                    columns:
                        table.Grid.Columns(
                            table.Columns.Select((column, i) =>
                            {
                                return i == 0
                                    ? table.Grid.Column(columnName: column.Name, header: column.Header, format: (item) => item.GetSelectLink(item.Id.ToString()))

                            }).ToArray())
                    )
            </div>
        </div>
    }
