kendoui grid cell editor of dropdownlist - kendo-ui

Question

I created a KendoUI grid where the first column uses a custom editor. After editing, it doesn't call request of update, however if it is not using editor it will call request of update. Why?
var columns = [
{ field: 'AccountId', title: '客户名称', locked: false, template: '#= me.detail.brandName(data, \'ID\') #', editor: accountGridEditor, width: 200 },
{ field: 'BankNo', title: '付款银行', template: '#= me.detail.format(data, \'Bank\') #', attributes: { style: 'text-align: left;' }, width: 150 },
{ field: 'UnLinkedAmount', title: '未分配', template: '#= me.detail.format(data, \'UnLinkedAmount\') #', attributes: { style: 'text-align: left;' }, width: 100 },
{ command: ["edit", "destroy"], title: " ", width: "250px" }
];
var dataSource = c.dataSourceOption({
transport: {
read: { url: url.api('Finance/FundJournal') },
update: { url: url.api('Finance/FundJournal', { action: 'post' }) },
destroy: { url: url.api('Finance/FundJournal', { action: 'delete' }), type: 'delete' },
parameterMap: function (data, type) {
console.log(type);
console.log(data);
if (type === 'read') return getReadParameters();
if (type === "update") return data;
if (type === 'create') return data;
if (type === 'destroy') return { id: data.Id };
return data;
}
},
schema: {
model: {
id: "Id",
fields: {
AccountId: { editable: true, nullable: false, validation: { required: true } },
BankNo: { editable: false},
UnLinkedAmount: { editable: false }
}
}
},
filter: [{ field: 'SubType', operator: 'neq', value: 'Id' }]
});
var grid = $("#result").kendoGrid({
dataSource: dataSource,
height: 550,
columns: columns,
editable: "inline",
save:function(e){$.ajax();}
}).data('kendoGrid');

Answer 1

If record property is set from dropdownlist something like this:
change: function() {
options.model.Name = this.value();
options.model.dirty = true;
}
it is necessary explicitly to set that model as dirty, to say to datasource that this record was modified and need to be updated. Otherwise, you can use set().
change: function() {
options.model.set('Name',this.value());
}
That way record is automatically marked as dirty in datasource.
