我目前正在对其他人开发的应用程序进行一些修改。该应用程序使用KendUI在网格上呈现数据。默认情况下，假设网格应该能够进行过滤和排序。当我打开网格过滤器并选择要过滤的特定字段时，出现状态500错误；
GET http://localhost/RFG/Workpermits?take=10&skip=0&page=1&pageSize=10&filter%5Blogic%5D=and&filter%5Bfilters%5D%5B0%5D%5Bfield%5D=Id&filter%5Bfilters%5D%5B0%5D%5Boperator%5D=eq&filter%5Bfilters%5D%5B0%5D%5Bvalue%5D=7&filter%5Bfilters%5D%5B1%5D%5Bfield%5D=ContractorName&filter%5Bfilters%5D%5B1%5D%5Boperator%5D=contains&filter%5Bfilters%5D%5B1%5D%5Bvalue%5D=Sor 500 (Internal Server Error)

有人可以帮我找出问题所在吗？
答案 0 :(得分：0)
我可以看到您已经将网格配置为使用“ serverFiltering”，并且您正在使用两种不同的配置，第一种是使用变量，然后在网格配置本身内部，我建议只使用一种，已将您的网格配置更新为：
$("#workPermitsGrid").kendoGrid({
autoBind: false,
dataSource: {
transport: { read: PTWApp.getSitePrefix() + "/Workpermits" },
schema:{
model:{
id: "Id",
fields:{
Id:{type:"number" },
StartDate:{type:"date" },
EndDate:{type:"date" }
}
}
},
pageSize: 10,
},
scrollable: {
virtual: true
},
sortable: true,
dataBound: WorkPermitsListView.onDataBind,
pageable: {
numeric: false,
previousNext: false
},
noRecords: { template: "<div class='noRecordsDiv'>No permits to display. Use search for more or contact the administrator for assistance.</div>" },
filterable: true,
columns: [
{
command: {
click: WorkPermitsListView.editWorkPermit,
name: "modify",
text: gridDefaultActionName
},
width: "70px"
},
{
field: "Id",
title: "Permit #",
width: "7%" ,
headerAttributes: { style: "white-space: normal"}
},
{
field: "Status",
title: "Status",
template: "#= WorkPermitsListView.addStatusImg(data)#",
width: "7%",
filterable:false,
headerAttributes: { style: "white-space: normal"},
editor: workPermitsListView.selectPermit
},
{
field: "StartDate",
title: "Start Date",
template: "#= PTWApp.ConvertDate(data.StartDate)#",
width: "7.5%",
filterable:false,
headerAttributes: { style: "white-space: normal"}
},
{
field: "EndDate",
title: "End Date",
template: "#= PTWApp.ConvertDate(data.EndDate)#",
width: "7.5%",
filterable:false,
format:"{0:MMM dd yyyy}",
headerAttributes: { style: "white-space: normal"}
},
{
field: "ContractorName",
title: "Contractor",
width: "8.5%",
headerAttributes: { style: "white-space: normal"}
},
{
field: "ContractorSupervisorName",
title: "Supervisor",
width: "8.5%",
filterable:false,
headerAttributes: { style: "white-space: normal"}
},
{
field: "ContractorSupervisorPhone",
title: "Phone #",
template: "#: WorkPermitsListView.formatPhone(ContractorSupervisorPhone) #",
width: "7.5%",
filterable:false,
headerAttributes: { style: "white-space: normal"}
},
{
field: "RequestedBy",
title: "Requester",
width: "7.5%",
filterable:false
},
{
field: "Attachments",
title: "Files",
template: "#= WorkPermitsListView.addFileImg(data)#",
filterable:false,
width: "6%"
},
{
field: "IsEvent",
title: "Events",
template: "#= WorkPermitsListView.addEventImg(data)#",
width: "5.5%"
},
{
field: "Description",
title: "Work Description",
width: "33.5%"
//, attributes: { "class": "shortText" } }
}
]
});
尝试一下，让我知道它是否有效。
