剑道 UI 网格批量编辑需要显示布尔值 true（复选框需要选中） false（复选框需要取消选中）

Question

Employee.cs 类就是这样的

 public class Employee
 {
     public int EmployeeID;
     public string Name;
 }

Order.cs 类就是这样的

 public class Order
 {
     public int OrderID { get; set; }
     public DateTime OrderDate { get; set; }
     public string OrderDescription { get; set; }
     public int EmployeeID { get; set; }
     public bool checker { get; set; }
     public bool Maker { get; set; }
     public bool Supervisor { get; set; }
 }

Home Controller 是这样的

 public class HomeController : Controller
 {
     public static List<Order> orderList = new List<Order> { 
             new Order {OrderID = 1, OrderDate = new DateTime(2012,8,1), EmployeeID = 1, OrderDescription = "Order Food",checker=true,Maker=true,Supervisor=true },
             new Order {OrderID = 2, OrderDate = new DateTime(2012,8,1), EmployeeID = 2, OrderDescription = "Order Office Materials",checker=false,Maker=true,Supervisor=true },
             new Order {OrderID = 3, OrderDate = new DateTime(2012,8,2), EmployeeID = 1, OrderDescription = "Order Production Materials",checker=true,Maker=true,Supervisor=true },
             new Order {OrderID = 4, OrderDate = new DateTime(2012,8,3), EmployeeID = 4, OrderDescription = "Order Food",checker=true,Maker=true,Supervisor=true },
             new Order {OrderID = 5, OrderDate = new DateTime(2012,8,4), EmployeeID = 3, OrderDescription = "Order Production Materials" ,checker=false,Maker=true,Supervisor=true},

         };

html页面Index.cshtml是这样的

@(Html.Kendo().Grid<GridSyncChangesWithOneRequest.Models.Order>()
 .Name("Grid")    
 .Columns(columns => {        
     columns.Bound(p => p.OrderID);
     columns.ForeignKey(p => p.EmployeeID,(System.Collections.IEnumerable)ViewData["employees"], "EmployeeID", "Name");
     columns.Bound(p => p.OrderDescription);
     columns.Bound(p => p.Maker);
     columns.Bound(p => p.checker);
     //columns.Bound(p => p.checker).HeaderTemplate("Checker").ClientTemplate("<input type='checkbox' id='#= ID#,#= Name#' class='grid_checkbox'/>");      
     columns.Bound(p => p.Supervisor); 
     columns.Bound(p => p.OrderDate).Format("{0:d}");
     columns.Command(c => {
         c.Destroy();
     });
 })    
 .ToolBar(toolBar => toolBar.Create())
 .Editable(editable => editable.Mode(GridEditMode.InCell))
 .Pageable()
 .Sortable()
 .Scrollable()
 .Filterable()
 .DataSource(dataSource => dataSource        
     .Ajax()      
     .ServerOperation(false)
     .Model(model => { 
         model.Id(p => p.OrderID);
         model.Field(p => p.OrderDescription).Editable(false);
         model.Field(p => p.EmployeeID).Editable(false);
         model.Field(p => p.OrderID).Editable(false);
         model.Field(p => p.Maker).Editable(false).DefaultValue(true);           
         model.Field(p => p.OrderDate).Editable(false);               
     })
     .Create(create => create.Action("Create", "Home"))
     .Destroy(destroy => destroy.Action("Delete", "Home"))
     .Read(read => read.Action("Read", "Home"))
     .Update(update => update.Action("Update", "Home"))       
 ) )

按下 saveChanges 会将所有当前更改发送到 服务器：

<button onclick="sendData()">Save Changes</button>

<script>  
 function sendData() {
     var grid = $("#Grid").data("kendoGrid"),
         parameterMap = grid.dataSource.transport.parameterMap;

     //get the new and the updated records
     var currentData = grid.dataSource.data();
     var updatedRecords = [];
     var newRecords = [];

     for (var i = 0; i < currentData.length; i++) {
         if (currentData[i].isNew()) {
             //this record is new
             newRecords.push(currentData[i].toJSON());
         } else if(currentData[i].dirty) {         
             updatedRecords.push(currentData[i].toJSON());
         }
     }

     //this records are deleted
     var deletedRecords = [];
     for (var i = 0; i < grid.dataSource._destroyed.length; i++) {
         deletedRecords.push(grid.dataSource._destroyed[i].toJSON());
     }

     var data = {};
     $.extend(data, parameterMap({ updated: updatedRecords }), parameterMap({ deleted: deletedRecords }), parameterMap({ new: newRecords }));

     $.ajax({
         url: "/Home/UpdateCreateDelete",
         data: data,
         type: "POST",
         error: function () {
             //Handle the server errors using the approach from the previous example
         },
         success: function () {
            alert("update on server is completed");

             grid.dataSource._destroyed = [];
            //refresh the grid - optional
             grid.dataSource.read();
         }
     })
 } </script>

我只需要显示 checkBox 而不是 True of False 而 编辑。有什么可能的解决方案吗？ !enter image description here

Answer 1

检查客户端模板中检查器字段的真假

columns.Bound(p=> p.checker).ClientTemplate("# if(checker==true){#" + "<input  type='checkbox'  checked='checked'  />" + "#}else{#" + "<input type='checkbox' />" + "#}#");

Answer 2

你可以使用这个 Telerik answer

或来自documentation：

columns.Bound(p => p.Enabled).ClientTemplate(
    "<input type='checkbox' value='#= ProductID #' " +
        "# if (Enabled) { #" +
            "checked='checked'" +
        "# } #" +
    "/>"
);
