I'm looking for a way to connect my open source Kendo UI Scheduler to a local database using javascript.
I've already started but got stuck because I can't find any helpful documentation on how to do this using javascript.
$(function () {
$('#scheduler').kendoScheduler({
views: [{type:"day", selected:true}],
dataSource:
{
transport:
{
read: { url: "@Url.Action("GetTasks","Schedules")", dataType: "json" },
update: { url: "@Url.Action("UpdateTask","Schedules")", dataType: "json" },
create: { url: "@Url.Action("CreateTask","Schedules")", dataType: "json" },
destroy: { url: "@Url.Action("DeleteTask","Schedules")", dataType: "json" },
parameterMap: function (options, operation) {
if (operation !== "read" && options.models) {
return { models: kendo.stringify(options.models) };
}
}
},
schema:
{
/* Define your actual models for your events here */
model:
{
/* See the available documentation for more information */
}
}
I've been looking on the Telerik documentation without any success besides that I looked for some clues here on stackoverflow but besides this thread https://stackoverflow.com/questions/23322409/how-to-bind-datasource-to-the-scheduler-in-kendo-ui-using-javascript I couldn't find anything helpful.
Can anybody point me in the right direction concerning useful documentation or an illustrative example binding the Kendo UI Scheduler to a local database using javascript?
Thanks in advance
