When doing "Range selection" with the DateTimePicker, I think I've found a bug:

Go to http://demos.kendoui.com/web/datetimepicker/rangeselection.html
Clear BOTH pickers
Click the calendar icon in the Start date control
1. Defaults to this month, but no days are displayed for picking
In the Start date picker, type in 2/11/2012 (or today's date) and press ENTER
In the End date picker, use the calendar icon to pick today's date

An entire month is added to the value in End date. For instance, picking toaday's date of 2/11/2012, the End date is actually set to 3/11/2012. Is this a Bug?

How to set grid grouping programatically

Good day,

I have the following scenario:
By default, the grid on my page loads data that is grouped by 4 fields.

The user has the ability to add or remove a grouping if he chooses to. I want to have a button on my page that resets the view to how it was when the page loaded, with the data grouped by the 4 fields.

I want to do this without reloading the page itself, because the call that returns the data takes too long unfortunately. How do I programatically group by a certain field (or group of fields) on the click of the reset button?

Anyone have any ideas?

Chart Visibility / VS2012 MVC 4 Mobile Application Project Template

I created a MVC 4 Mobile Application using the VS2012 Project Template. My page has a Kendo Chart on it. After clicking an ActionLink the chart is not displaying. But, if I simply click "Refresh" the chart is right there. Maybe some of the project template javascript is hiding the chart? I was wondering if someone might have some insight on how keep the chart visible the first time the page loads? My code is below.

HomeController.cs:

using MobileActionLink.Models;

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.Mvc;

namespace MobileActionLink.Controllers

{

public class HomeController : Controller

{

public ActionResult Index(int appID = 1)

{

ViewBag.Message = "App ID = " + appID;

var listHistory = LoginHistoryRepository.ListHistory();

//APPLY THE FREQUENCY RULE

foreach (var item in listHistory)

{

var date = item.LoginDateTime.Date;

var hours = item.LoginDateTime.Hour;

//hourly

var locDT_Hourly = date.ToShortDateString() + " " + hours + ":00:00.000";

//daily

var locDT_Daily = date.ToShortDateString() + " 00:00:00.000";

//round the login datetime to hour or day as specified by the Frequency DD selection

item.LoginDateTime = Convert.ToDateTime(locDT_Hourly);

}

//FILTER THE HISTORY LIST

IEnumerable<ChartHist> myRow = from row in listHistory

where row.LoginApplicationID == appID

select row;

//apply frequency filter

myRow = myRow.Where(f => f.ScriptFrequency == 1).ToList();

//need duration averages now, since datetime of login will not be unique

//also, split up pass/fail statuses

myRow = from row in myRow

group row by row.LoginDateTime into grp

select new ChartHist

{

LoginDateTime = grp.Key,

LoginDuration_Pass = grp.Average(d => d.LoginDuration_Pass),

LoginDuration_Fail = grp.Average(d => d.LoginDuration_Fail)

};

//apply date filters

myRow = myRow.Where(f => f.LoginDateTime >= DateTime.Today.AddDays(-7) && f.LoginDateTime <= DateTime.Today).ToList();

////get the app name and assign it to a view bag property

var appName = "";

var listApps = LoginApplicationRepository.ListApplications();

var appNames = from a in listApps

where a.LoginApplicationID == appID

select a.LoginAppName;

foreach (var item in appNames)

appName = item;

ViewBag.AppName = "APP NAME";

var chartApp = new ChartApp();

chartApp.LoginApplicationID = appID;

chartApp.LoginAppName = appName;

var chartViewModel = new ChartsMobileViewModel();

chartViewModel.ChartHistories = myRow.ToList();

chartViewModel.LoginApplications = listApps.ToList();

chartViewModel.ChartApp = chartApp;

return View(chartViewModel);

}

Kendo dropdown list cascade event can't be bound to a function

//*******************WORKS*************************

$("#dropdownlist").kendoDropDownList({

cascade: alert("works")

});

//*******************DOES NOT WORK**************

$("#dropdownlist").kendoDropDownList({

cascade: function(){

alert("Does not work");

},

});

The cascade event of the kendo dropdown works when there is a single line of code in it, but when I try to bind a function to the cascade event doesn't trigger, is there a problem in my syntax.

I also made a working demostration of the problem in JSFiddle

ToDataSourceResult doesn't preserve the default order when 'sort' http variable is not set

Hi,
I'm using EF and I want to add a default order for items in a grid. To do that I've added a call to OrderBy and after that I convert the result to DataSourceResult:

var data = context.Subjects.OrderBy(x => x.ScreeningNumber).ToDataSourceResult(request);

The problem is that if there is no order set (this.HttpContext.Request.Form["sort"] is "") I expect it to use my default ordering, but for some reason ToDataSourceResult completely removes ordering. How can I keep my default order in such cases?

Thanks in advance.

Choosing a font other than inherited before inserting text

I want to be able to chose a font from the dropdown then start typing in the editor and have it honor this selection. Currently I have to type the text first, then highlight it and then change it to the font I want.

Is there a way to set the font to a font type other than inherited before I type the text?

If so I would also like to be able to set this in Javascript.

Javascript Template Example In Overview doesn't work

Can someone point me to a functional jsFiddle or equivalent that has something like the example shown here: http://docs.kendoui.com/getting-started/framework/templates/overview under External Templates and Expressions

Note the improper <ul> in the example, which to me is indicative of this not being code that was pasted from a successful running example.

Anyway, posting code snippets is not enough - post a link to a working example please : )

Thank You

Kendo Grid footerTemplate disappears after filtering

I have this problem and the best way to describe is through these steps:
Kendo Grid is setup with fixed width columns and filters are enabled.
A column on the far left side of the grid is defined with a footerTemplate
The user scrolls the the right of the grid to see the column with the footerTemplate
The user filters on a column
The footerTemplate disappears however; the horizontal scrollbar appears to not change position.
"Wiggling" the horizontal scrollbar resolves the missing footerTemplate.

I have attached a zip containing the problem that I captured with the Windows Problem Steps Recorder.
