Я использую kendoDropDownList и имею следующий код:
<div id="memberNotInit-grid"></div>
<script>
$(document).ready(function () {
$("#memberNotInit-grid").kendoGrid({
dataSource: {
type: "json",
transport: {
read: {
url: "@Html.Raw(Url.Action("MemberNotInitList", "RandomPoolInit"))",
type: "POST",
dataType: "json",
data: function() {
var data = {
};
addAntiForgeryToken(data);
return data;
}
}
},
schema: {
data: "Data",
total: "Total",
errors: "Errors"
},
error: function(e) {
display_kendoui_grid_error(e);
// Cancel the changes
this.cancelChanges();
},
pageSize: @(Model.PageSize),
serverPaging: true,
serverFiltering: true,
serverSorting: true
},
pageable: {
refresh: true,
pageSizes: [@(Model.AvailablePageSizes)],
@await Html.PartialAsync("_GridPagerMessages")
},
editable: {
confirmation: "@T("Common.DeleteConfirmation")",
mode: "inline"
},
scrollable: false,
columns: [
{
field: "FirstName",
title: "@T("PoolMemberList.Fields.FirstName")",
width: 150
},
{
field: "LastName",
title: "@T("PoolMemberList.Fields.LastName")",
width: 150
},
{
field: "Status",
template: columnTemplateFunction
},
{
field: "Reason",
width: 150,
template: "<input data-bind='value:Reason' class='reasonTemplate' />",
//hidden: true
}
],
dataBound: function (e) {
var grid = e.sender;
var items = e.sender.items();
items.each(function (e) {
var dataItem = grid.dataItem(this);
var ddt = $(this).find('.dropDownTemplate');
$(ddt).kendoDropDownList({
value: dataItem.value,
dataSource: ddlDataSource,
dataTextField: "displayValue",
dataValueField: "Status",
change: onDDLChange
});
var reason = $(this).find('.reasonTemplate');
$(reason).keydown(reasonChange);
reason.hide();
});
}
});
var ddlDataSource = [
{
Status: @((int)DriverRandomPoolStatus.Enrollment),
displayValue: "Enrollment"
},
{
Status: @((int)DriverRandomPoolStatus.Active),
displayValue: "Active"
},
{
Status: @((int)DriverRandomPoolStatus.Excused),
displayValue: "Excused"
}
];
function columnTemplateFunction(dataItem) {
var input = '<input class="dropDownTemplate"/>'
return input
};
function onDDLChange(e) {
var element = e.sender.element;
var row = element.closest("tr");
var grid = $("#memberNotInit-grid").data("kendoGrid");
var dataItem = grid.dataItem(row);
dataItem.set("Status", e.sender.value());
//alert(e.sender.value());
if (dataItem.Status == @((int)DriverRandomPoolStatus.Active)) {
$.ajax({
method: "POST",
url: "@Html.Raw(Url.Action("ChangeMemberStatus", "RandomPoolInit"))",
data: { id: dataItem.Id, status: dataItem.Status }
}).done(function () {
grid.tbody.find("tr[data-uid=" + dataItem.uid + "]").hide();
grid.pager.refresh();
});
}
if (dataItem.Status == @((int)DriverRandomPoolStatus.Excused)) {
grid.tbody.find("tr[data-uid=" + dataItem.uid + "]").find('.reasonTemplate').show();
var ddl = grid.tbody.find("tr[data-uid=" + dataItem.uid + "]").find('.dropDownTemplate');
//ddl.value(dataItem.Status);
}
};
function reasonChange(event) {
if (event.keyCode === 13) {
var element = event.target;
var row = element.closest("tr");
var grid = $("#memberNotInit-grid").data("kendoGrid");
var dataItem = grid.dataItem(row);
var r = grid.tbody.find("tr[data-uid=" + dataItem.uid + "]").find('.reasonTemplate').val();
$.ajax({
method: "POST",
url: "@Html.Raw(Url.Action("ChangeMemberStatus", "RandomPoolInit"))",
data: { id: dataItem.Id, status: dataItem.Status, reason: r }
}).done(function () {
grid.tbody.find("tr[data-uid=" + dataItem.uid + "]").hide();
grid.pager.refresh();
});
}
}
});
</script>
, но когда мы выбираем «Исключено» из выпадающего списка, значение выпадающего списка сбрасывается до Enrollment (первое значение из выпадающего списка). Почему так и как это исправить?
