剑道网格中总和列的总和

Question

我有kendo grid javascript分组如下

group: {
                        field: "ResourceName",
                        aggregates: [
                           { field: "WeekOneUtilization", aggregate: "sum" },
                            { field: "WeekTwoUtilization", aggregate: "sum" },
                             { field: "WeekThreeUtilization", aggregate: "sum" },
                              { field: "WeekFourUtilization", aggregate: "sum" }
                        ]
                    },
                    aggregate: [{ field: "ProjectName", aggregate: "count" },
                                { field: "WeekOneUtilization", aggregate: "sum" },
                            { field: "WeekTwoUtilization", aggregate: "sum" },
                             { field: "WeekThreeUtilization", aggregate: "sum" },
                              { field: "WeekFourUtilization", aggregate: "sum" }]

我希望获得四周的总和

你的代码是用JavaScript完成的，这真是太棒了......现在你可能是最接近上帝（你的网格）的东西...所以让我们来吧工作

1）转到你的数据源模型，并在那里定义一些方便的计算的东西......例如。

var yourDataSource = new kendo.data.DataSource({
    schema:{
        model: {
            // Typical blah blah here
            id: 'your-id-field',
            fields: {
               // Typical field declaration blah blah
            },
            // This handy function will calculate
            // the sum of the 4 weeks in your row
            sumOfAllWeeks: function(){                    
               return this.get('WeekOneUtilization') + 
                      this.get('WeekTwoUtilization') + 
                      this.get('WeekThreeUtilization') + 
                      this.get('WeekFourUtilization');                 
            }
        }     
    }
});

2）现在你可以将这个闪亮的全新计算字段添加到你的聚合配置中，语法有点不同。

{ field: "sumOfAllWeeks()", aggregate: "sum" }

3）但是，如果你想让kendo处理网格中计算属性的聚合，就会出现一个错误（可能现在已修复）......他错误地试图调用你的字段名称＆＃34; sumOfAllWeeks（ ）＆＃34;作为一个函数而不是累加器，不像他用普通场。因此，在您的网格中，您必须将模板用作函数。

让我们通过在您的网格中为您的计算机创建一个新列来说明这一点......

 // Your grid fields declaration
 columns:[
     // Here you may have your columns declared,
     // as shown in your picture... so I save the blah blah
     // Now we declare a column for your computed.
     {
         field: 'sumOfAllWeeks()',
         aggregates: 'sum', 
         // This handles the group footer template
         groupFooterTemplate: function(data){
           return data['sumOfAllWeeks()'].sum;
         },
         // This handles the table footer template
         footerTemplate: function(data){
           return data['sumOfAllWeeks()'].sum;
         }
     }
 ]

Answer 2

您可以使用ClientTemplate：

columns.Bound(p => p.Total).ClientTemplate("#= WeekOneUtilization + WeekTwoUtilization + WeekThreeUtilization + WeekFourUtilization #");
