问题描述

我正在开发一个Kendo Grid,它有一个Status列,它是几个其他列的状态汇总。我将各个状态跟踪为整数值,聚合列应显示最少的状态。现在,使用模板,我能够很好地呈现Status列的文本,但问题是我希望此列可以过滤。在计算该值时,这不起作用。

I am working on a Kendo Grid which has a Status column that is an aggregate of statuses of several other columns. I track the individual statuses as integer values and the aggregate column should show the least of the statuses. Now, using template, I am able to render the text for the Status column fine, however, the problem is that I want this column to be filterable. This is not working as the value is calculated.

在DataSource中,这是我声明自定义字段的方式,

In DataSource, this is how I have declared the custom field,

schema: {
    model: {
        Status: function () {
            return helper.GetStatus(this.EntriesStatus);
        }
    }
}

这是我用它的方式在列定义中,

This is how I used it in the Column definition,

{
    field: "Status",
    title: "Status",
    width: "100px",
    filterable: true,
    template: kendo.template("#if (HasError) {# <strong class='clrRed' > \#= Status() #\ </strong> #} else { # \#= Status() #\ #} #"),
    hidden: false,
    menu: false
}

有人能指出我出错的地方或更有效的出路吗?

Could anyone point out where I am going wrong or a more efficient way out?

推荐答案

而不是将 Status 定义为中的函数model ,将其作为计算字段添加到 model.parse 中。例如:

Instead of defining Status as a function in the model, add it in model.parse as a computed field. Ex:

schema: {
    parse: function (d) {
        $.each(d, function (idx, elem) {
            elem.Status = helper.GetStatus(elem.EntriesStatus);
        });
        return d;
    }
}

然后在模板中删除()

template: kendo.template("#if (HasError) {# <strong class='clrRed' > \#= Status #\ </strong> #} else { # \#= Status #\ #} #"),
