将对象数组绑定到Kendo网格弹出式多选对象 [英] Binding array of object to Kendo grid popup multiselect
问题描述
我正在尝试将一组ID值对绑定到kendo网格弹出编辑器.
I'm trying to bind an array of id-value pairs to a kendo grid popup editor.
让一切都可以用来创建新记录.弹出编辑器将加载自定义编辑器,并成功将数据提交到控制器.
Got everything to work for creating a new record. Popup editor loads the custom editor and successfully submits the data to the controller.
问题是当我尝试编辑记录时.记录正确显示在该行中,但是当我尝试对其进行编辑时,multiselect无法保存这些值.
The problem is when I try to edit records. The records displays properly in the row, but when I try to edit it, the multiselect does not hold the values.
网格标记
$("#ProjectSites-SubContract-grid").kendoGrid({
dataSource: {
type: "json",
schema: {
data: "Data",
total: "Total",
errors: "Errors",
model: {
id: "Id",
fields: {
DateOfContract: { type: 'date', editable: true },
DateOfCompletion: { type: 'date', editable: true },
AmountOfContract: { type: 'number', editable: true },
Contractor: { defaultValue: { id: "", name: "" } }
}
}
},
},
columns: [
{
field: "ScopeOfWork",
title: "Scope of Work",
template: "#=parseScopeOfWork(ScopeOfWork)#",
editor: scopeOfWorkEditor
},
]
});
});
工作范围编辑器
function scopeOfWorkEditor(container, options) {
$('<input data-text-field="name" data-value-field="id" data-bind="value:ScopeOfWork"/>')
.appendTo(container)
.kendoMultiSelect({
dataSource: {
data: [
@foreach (var scopeOfWork in Model.AvailableScopeOfWork)
{
<text>{ id : "@scopeOfWork.Value", name : "@scopeOfWork.Text" },</text>
},
]
}
});
parseScopeOfWork- 伙计们使用此方法遍历对象列表并合并名称.
parseScopeOfWork - this method guys iterates through the object list and concats the name.
function parseScopeOfWork(scopeOfWork) {
var result = "";
for (var i = 0; i < scopeOfWork.length; i++) {
result += scopeOfWork[i].Name;
if (i < scopeOfWork.length - 1)
{
result += ", <br/>";
}
}
return result;
}

推荐答案
您要将SpaceOfWork
绑定到新的小部件,但是该小部件如何知道您的模型?我的意思是,仅使用data-bind
不会将模型绑定到小部件,它本身无法确定.我有两个建议:
You're binding the SpaceOfWork
to the new widget, but how that widget knows your Model ? I mean, just using data-bind
doens't binds the model to the widget, it can't figure that by itself. I have two suggestions:
-
在小部件的初始化中设置值:
Set the value in the widget's initialization:
.kendoMultiSelect({
value: options.model.ScopeOfWork
将模型永久绑定到小部件:
Bind the model to the widget for good:
let $multiSelect = $('<input data-text-field="name" data-value-field="id" data-bind="value:ScopeOfWork"/>');
kendo.bind($multiSelect, options.model);
$multiSelect
.appendTo(container)
.kendoMultiSelect({ ...
