问题描述
我有一个kendo Dropdown列表，它可以正常工作，但是我需要使它成为没有按钮的实时列表.每当我在下拉列表中选择一项时，它就会自动更新网格中的内容或基于网格的查询在下拉列表中选择.
i have a kendo Dropdown list its working but i need to make it a live one without the button... whenever i pick one item inside the dropdown it automatically update whats inside my grid or the query on my grid base on the selected on the dropdown list.
这是我的代码:
@using (Html.BeginForm())
{
<input type="hidden" id="hiddenUser" name="hiddenUser" value="@userId" />
<p>
<input id="ddlWorker" name="ddlWorker" style="width: 250px;" value="@ddlWorker" />
<input type="submit" value="Filter Workers by Position" class="styledButton" />
</p>
}
JS:
var userId = $("#hiddenUser").val();
$("#ddlWorker").kendoDropDownList({
dataTextField: "JobCode",
dataValueField: "ID",
autoBind: false,
optionLabel: {
JobCode: "--- Please Select Position ---",
ID: ""
},
// define custom template
template: '<h5>${ data.JobCode }</h5>',
dataSource: {
transport: {
read: {
url: '/Worker/LoadWorkerDropdownList?userId=' + userId,
dataType: "json",
type: "POST"
}
}
}
});
var dropdownlist = $("#ddlWorker").data("kendoDropDownList");
dropdownlist.list.width(250);
我的网格控制器
public JsonResult LoadWorkerList( string search, int? positionSelected, int? statusValue)
{
// check if search string has value
// retrieve list of workers filtered by search criteria
var list = (from a in db.Workers
where a.LogicalDelete == false

};
wlist.Add(ci);
}
if (positionSelected.HasValue)
{
var workerIdList = new List<Int32>();
var filterList = (from a in db.Client_Worker_Position

|| (posStartTime < availStartTime && posEndTime > availEndTime))
{
workerIdList.Add(row.ID);
}
}
}
}
}
var toBeList = (from a in listSelect
where a.LogicalDelete == false
select a).ToList();
var setToList = toBeList.Select(x => x.ID).Except(filterList.Select(y => y.WorkerAvailabilityId)).ToList();

}).ToList();
var distinctList = selectedPosition.GroupBy(x => x.ID)
.Select(g => g.First())
.ToList();
wlist = distinctList.ToList();
}
if (!search.Equals("Search Worker"))
{
var wolist = (from a in wlist

}
ViewBag.positionSelected = positionSelected;
return Json(wlist.ToList().OrderBy(p => p.FirstName.ToLower()), JsonRequestBehavior.AllowGet);

推荐答案
这是Kendo DropDownList的工作副本，它将更改Kendo Grid的值.
Here is a working copy of Kendo DropDownList which will change the value of a Kendo Grid.
我的HTML:我已经为剑道和常规标记链接了必要的css/js文件，以挂钩剑道控件.
My HTML: I've linked the necessary css/js files for kendo and general markup to hook kendo controls.

<div>
<label class="control-label" for="shiftName">Shift</label>
<div class="controls">

<br />
<div class="box-content">
<label class="control-label" for="shiftName">Operator</label>
<div id="OperatorGrid"></div>
<div class="clearfix"></div>
</div>
</div>
我的JavaScript:
My javascript:
//Initialize Kendo DDL
$(document).ready(function () {
$("#ShiftInputs").kendoComboBox({
dataTextField: "text",
dataValueField: "value",
dataSource: ShiftData,
index: 0,
change: onChange
});
//Loading Kendo Grid with all data
$("#OperatorGrid").data("kendoGrid").dataSource.read();
});
//DDL values
var ShiftData = [{ text: "ALL", value: "ALL" }, { text: "DAY", value: "DAY" }, { text: "NIGHT", value: "NIGHT" }];
//DDL change event function, hitting Home controller, function StatusCmbChanged.
function onChange() {
var statusValue = $("#ShiftInputs").val();
$.ajax({
url: 'Home/StatusCmbChanged',
type: "POST",
data: { "statusValue": statusValue },
dataType: "json"
}).done(delayedRefresh());
}
function delayedRefresh() {
window.setTimeout(Refresh, 500);
}
function Refresh() {
$("#RefreshMessage").show("slow").delay(5000).hide("slow");
$("#OperatorGrid").data("kendoGrid").dataSource.read();
}
//Main Kendo Grid
$("#OperatorGrid").kendoGrid({
dataSource: {
transport: {
read: {

type: "POST",
contentType: "application/json",
dataType: "json"
},
update: {

contentType: "application/json; charset=utf-8",

dataType: "json"
},
parameterMap: function (data, operation) {
if (operation != "read") {
return kendo.stringify(data.models);
}
}
},
serverPaging: false,
pageSize: 10,
schema: {
model: {
id: "ID",
fields: {
ID: { editable: false },
Title: { validation: { required: true } },
Name: { editable: true },
Hours: { editable: true, type: "number", validation: { required: true, min: 0, step: 0.25 } },
Shift: { editable: true },
Comments: { editable: true }
}
}
}
},
pageable: {
refresh: true,
pageSizes: true
},
sortable: true,
autoBind: false,
columns:
[
{ field: "Title", width: 100 },
{ field: "Name", width: 120 },
{ field: "Hours", width: 100 },
{ field: "Shift", width: 100 },
{ field: "Comments", width: 100 },
]
});
我的MVC代码: 控制器:
My MVC Codes: Controller:
public ActionResult Index()
{
return View();
}
我的网格数据表:
static DataTable GetTable()
{
DataTable table = new DataTable();
table.Columns.Add("ID", typeof(int));
table.Columns.Add("Title", typeof(string));
table.Columns.Add("Name", typeof(string));
table.Columns.Add("Hours", typeof(int));
table.Columns.Add("Shift", typeof(string));
table.Columns.Add("Comments", typeof(string));
table.Rows.Add(0, "Mr", "Indocin David", 12, "DAY", "Good sprit");
table.Rows.Add(1, "Mr", "Enebrel Sam", 8, "NIGHT", "");
table.Rows.Add(2, "Dr", "Hydralazine Christoff", 12, "DAY", "");
table.Rows.Add(3, "Mrs", "Combivent Janet", 12, "DAY", "");
table.Rows.Add(4, "Miss", "Dilantin Melanie", 8, "NIGHT", "Lazy");
table.Rows.Add(5, "Mr", "Tim Melanie", 14, "DAY", "");
table.Rows.Add(6, "Mr", "Robin Sriboski", 6, "NIGHT", "");
table.Rows.Add(7, "Mrs", "Anna Frank", 13, "NIGHT", "");
table.Rows.Add(8, "Mr", "Dimitri Petrovich", 9, "DAY", "Hard worker");
table.Rows.Add(9, "Mr", "Roberto Carlos", 7, "NIGHT", "");
table.Rows.Add(10, "Mrs", "Stepheny Abraham Lincoln", 13, "DAY", "");
return table;
}
我的Kendo网格阅读:
My Kendo Grid Read:
[HttpPost]
public ContentResult GetOperatorData([DataSourceRequest]DataSourceRequest request)
{
string OperatorJsonData = "";
DataTable table = GetTable();
string Shift = Session["CurrentShift"] as string;
if (!string.IsNullOrEmpty(Shift) && (Shift == "DAY" || Shift == "NIGHT"))
{
OperatorJsonData = JsonConvert.SerializeObject(from myRow in table.AsEnumerable()
where myRow.Field<string>("Shift") == Shift
select new
{
ID = myRow.Field<int>("ID"),
Title = myRow.Field<string>("Title"),
Name = myRow.Field<string>("Name"),
Hours = myRow.Field<int>("Hours"),
Shift = myRow.Field<string>("Shift"),
Comments = myRow.Field<string>("Comments")
});
}
else
{
OperatorJsonData = JsonConvert.SerializeObject(table);
}
return new ContentResult { Content = OperatorJsonData, ContentType = "application/json", ContentEncoding = Encoding.UTF8 };
}
我的Kendo DropDownList onChange Ajax调用命中点:
My Kendo DropDownList onChange Ajax call hit point:
[HttpPost]
public void StatusCmbChanged(string statusValue)
{
if (!string.IsNullOrEmpty(statusValue))
{
Session.Remove("CurrentShift");
Session["CurrentShift"] = statusValue;
}
}
