Kendo网格控件中的DropDownList(通过ClientTemplate) [英] DropDownList in kendo grid control (by ClientTemplate)

问题描述

我需要像对待EditorTemplateName一样对ClientTemplate采取行为. 所以我想做这样的事情:

I need to make behavor for ClientTemplate like we have for EditorTemplateName. So I want to make something like this:

模板:

@(
     Html.Kendo().DropDownListFor(m => m)        
            .BindTo((SelectList)ViewData["ExamResults"])
                .Template("#:Value# #:Text#")
                .DataTextField("Text")
                .DataValueField("Value")
            .Events(e => e
                .Change("examResultOnDropDownChange")
                .Open("examResultOnOpen"))
 )

并将列添加到网格中:.EditorTemplateName("ExamResultGridForeignKey")

And adding column into grid: .EditorTemplateName("ExamResultGridForeignKey")

但我要:.ClientTemplate("ExamResultGridForeignKey") 或类似的东西(但它不起作用):

but I want to: .ClientTemplate("ExamResultGridForeignKey") or something like that (but it doesnt work):

.ClientTemplate(
                Html.Kendo()
                    .DropDownList()
                    .Name("#=Id#")
                    .BindTo((SelectList)ViewData["ExamResults"])
                    .Template("#:Value# #:Text#")
                    .DataTextField("Text")
                    .DataValueField("Value")
 )

使用DropDownList以不可编辑的方式(当我们显示值时)创建字段的所有操作看起来就像可编辑的DropDownList.

All that I need to make field with DropDownList in not editable mode (when we display value) looks like editable DropDownList.

推荐答案

这是呈现我的下拉列表的方式. IsInForecast是一个布尔字段. If If所做的所有事情都是根据IsInForecast属性的值选择正确的ddl值(对/错).您将不得不根据需要对其进行调整.

This is how my dropdown list is being rendered. IsInForecast is a bool field. All the If else is doing is having the correct ddl value (true/false) selected based on the value of the IsInForecast property. You're gonna have to tweak it to your needs.

columns.Bound(m => m.IsInForecast).Title("Is Forecasted").ClientTemplate(

   "# if (IsInForecast == true) { #" +

                          "<select id='#= OrderId #' onchange=save('#= OrderId #'); style='Width: 80px; color: 'navy' > " +
                            "<option id='yes' selected value='1'>Yes</option>" +
                            "<option id='no' value='0'>No</option>" +

                            "</select>" +
                     "# } else { #" +
                          "<select id='#= OrderId #' onchange=save('#= OrderId #'); style='Width: 80px; color: 'navy' > " +
                            "<option id='yes'  value='1'>Yes</option>" +
                            "<option id='no' selected value='0'>No</option>" +
                         "# } #" 
            );             

在看到"<select id='#= OrderId #'的位置，该位置将ddl ID字段设置为，以便您知道正在编辑的下拉列表/记录. onchange=save('#= OrderId #');正在调用JS函数，该函数将模型属性OrderId传递给该方法.要获得刚刚更改的正确ddl的选定值，可以执行此操作.

Where you see "<select id='#= OrderId #' that is setting the ddl ID field to so you know which dropdownlist/record you are editing. onchange=save('#= OrderId #'); is calling a JS function that passes the model property OrderId to the method. To get the selected value of correct ddl you just changed you can do this.

save(orderId) function{
  var ddl = # + orderId;
  var getSelectedValue = $(ddl).val();
}  

这将呈现标准DDL.您可以在此处查看文档

This will render a standard DDL. You can check out the documentation here
