如何在asp.net mvc3中显示矩阵表？ [英] How can I display a matrix table in asp.net mvc3?

问题描述

我在一个小项目中涉及使用实体框架和asp.net mvc3在矩阵视图中显示多对多关系数据库。涉及的三个表格是SalesPerson（行标签），产品（列标签）和销售额：

如何在asp.net mvc3中开发/生成这种视图？

 < table> 
< tr> 
< th>< / th> 
 @foreach（模型中的变量）
 {
 foreach（var p in m.Products）
 {
< th> @ p.ProductName< / th> ; 
} 
} 
< / tr> 
 
 @foreach（模型中的var m）
 {
 foreach（var s in m.SalesPersons）
 {
< tr> 
< td> @ s.PersonName< / td> 
 
< / tr> 
} 
} 
 @ *销售：a.Amount * @ 
< / table> 
  

解决方案

使用与此类似的LINQ查询转换数据

  var salesTable = 
 from s in m.S.Sales 
 group s by s.SalesPerson.Label into g 
选择新的
 {
 rowKey = g.Key，
 rowData = g.Select（s => new {Product = s.Product，Amount = s.Amount} ）.OrderBy（s => s.Product.Label）
}; 
  

生成表格行很容易

  @foreach（var tableRow in salesTable）
 {
< tr> 
< td> @ tableRow.rowKey< / td> 
 @foreach（var sale in tableRow.rowData）
 {
< td> @ sale.Amount< / td> 
} 
< / tr> 
} 
  

I'm on a little project that involves using entity framework and asp.net mvc3 to display many to many relationship database in a matrix view. The three tables involved are SalesPerson (Row label), Product(Column label) and Sales:

How can I develop/generate this kind of view in asp.net mvc3 ?

<table>
<tr>
    <th></th>
    @foreach (var m in Model)
    {
        foreach (var p in m.Products)
        {
            <th>@p.ProductName</th> 
        }           
    }
</tr>

    @foreach (var m in Model)
    {               
        foreach (var s in m.SalesPersons)
        {
          <tr>
               <td>@s.PersonName</td>

          </tr> 
         }
     }  
 @*Sales: a.Amount*@    
</table>

解决方案

Transform your data using a LINQ query similar to this one

var salesTable =
    from s in m.Sales
    group s by s.SalesPerson.Label into g
    select new
    {
        rowKey = g.Key,
        rowData = g.Select(s => new { Product = s.Product, Amount = s.Amount }).OrderBy(s => s.Product.Label)
    };

Generating table rows is then easy

@foreach (var tableRow in salesTable)
{
    <tr>
        <td>@tableRow.rowKey</td>
        @foreach (var sale in tableRow.rowData)
        {
            <td>@sale.Amount</td>
        }
    </tr>
}
