How would one have a tick line drawn to represent the current time?

I am looking to have a red line drawn (on current day) on the scheduleview that represents the current time when the schedule is refreshed. This would have to work for all views except the month view. Is this possible?

Problems copy/paste of a phone number

Using the RadMaskedTextInput with Mask="(###) ###-####", I type in a phone # of (111) 222-3333, then copy it. The clipboard has "(111) 222-3333", but when I paste it into another RadMaskedTextInput control with the same properties or even copy it back to the same control the result value is "(111) 22-2333". It doesn't seem to know what to do with the space between the ")" and the "2". Is there some property I need to set to make the control work properly?

Yes, I know I can extend the control and override the HandlePaste to remove the spaces of the clipboard text before pasting into the control, but there must be another way to make it work.

Thanks in advance.

CPU Usage when Idle Due to Timer

I have observed that any application with a RadGridView consumes CPU time even when the application is idle. Using Spy++, you can verify this and see thousands of WM_TIMER messages being posted when a RadGridView is added to an application. I have a simple repro app. Full XAML below. Just comment out the RadGridView, and the behavior goes away. You can see using Process Explorer that even when the application is idle there is CPU usage, and using Spy++ you can see the timer events being fired rapidly. This causes a large number of context switches and slows down performance noticeably.

Framework: .Net 4.5
Telerik Version: 2014.1.331.45

<Window x:Class="GridViewTimer.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
        Title="MainWindow" Height="350" Width="525">
    <telerik:RadGridView />
</Window>

Resizing textboxes and comboboxes

1.

I have a radgridview, which contains RadRibbonGroups, which contains comboxboxes and textboxes.

However, I would also like to be able to resize the textboxes and comboboxes in the medium state. I could program it in XAML if I knew how to bind to the RadRibbonGroup to get the current variant used. Or how to use wrap my controls in RadCollapsiblePanel inside the ribbongroup and bind to a property which contains the current state (small, medium, large).

? Is there a way to bind to the the current size variant of the group? I dont know which property to use.

2.

On another RadGridView, the RadRibbonGroups does not contain RadCollapsiblePabel and when it collapses, it collapses into a single collapse into a single button with an (ugly) standard picture.

? Is there any way to change this picture?

Thanks

CurrentTimeIndicador in UTC

Hi,

I am working on an application where I have to display the Current Time Indicator in UTC but there is no option or property to set it on the control.

Is there a way to do this? Do you plan to have this in the next release (The R2 2017 release of UI for WPF)?

I found a similar issue here: http://www.telerik.com/forums/currenttimeindicator-in-utc

Kind regards,

Soares

DateTimeContinuousAxis Ticks

Hi,

The scenario: a zoommable chart with a DateTime axys that contains a lot of points, approxymately one each 5 or 6 minutes for years.

I set the X Axys MaximumTicks property to 10 and all work good.

But:

1) If I'm looking a range of years the time is not interesting for me
2) If I'm looking a range of years I prefer that any ticks go exaclty to one day (1/3/2013 00:00:00 instead of 1/3/2013 12:23:45)
3) If I'm looking a range of hours the time is really important

How to menage manually the parameters MajorStepUnit and MajorStep?
The ActualRangeChanged event don't exists!

Thank's
marc.
