Problems with BackColor

I'm using the following method to change the background colors on my scheduler cells.

List<SchedulerDayViewElement> dayViews = ((SchedulerDayViewGroupedByResourceElement)radScheduler1.SchedulerElement.ViewElement).GetDayViewElements();

foreach (SchedulerDayViewElement dve in dayViews) {

foreach (SchedulerCellElement sce in dve.DataAreaElement.Table.GetCells()) {

sce.BackColor = Color.FromArgb(230, 230, 230);

}

This is a simplified example, as I have more logic in my application to figure out what colors certain cells should be.

The problem is when I set that BackColor property the whole cell gets all whacked out. From what I can tell, not only is it changing the backcolor, but also the "hoverbackcolor" and the "selectedbackcolor", both of which I have no idea how to set. Or not set, for that matter.

Also, what is BackColor2, BackColor3, BackColor4?

CellMouseEnter- & CellMouseLeave-Events?

Are there any of those Events?
I need to change the value of a cell (Databound to BindingList with INotifyPropertyChanged) if the mouse enters a cell and reset the value if the mouse leaves the cell.
How is this possible?

Radscrollable Panel

Hi

One
Is there any way I can get the radscrollable panel to do the following three requirements programatically in vb.net
1 - Scroll to the top (of the panel)
2 - Scroll to the middle (of the panel)
3 - scroll to the end (of the panel)

Ideally I want to see a quick animation of the scroll taking place till it reaches the either point.

Two
Can you tell me how the following works (what it does):
Me.RadScrollablePanel1.VerticalScrollbar.PerformScrollTo
(I tried using it as follows: Me.RadScrollablePanel1.VerticalScrollbar.PerformScrollTo(new Point(0,200)) but it did nothing)

Three
Is there any link for more documentation on this control.

DateTimePicker Behaviour

Hello,

I have some issues with the behavoiur of the RadDateTimePicker which confuses me alot.
We are using the 2011.3.11.1219 Version of Telerik.

When I load a form I have an initial value which can be a DateTime or can be null. If the value is null the DateTimePicker on the should display a string lilke "No Value", if you click on the DateTimePicker to specify a Date or if you click on the DropDown Button, the current Day should be preselected. If the initial value is not null the DateTime should be displayed immediately if the form is shown.

If the value is null I have tried the following:

rdtp.NullText = "No Value";
rdtp.NullableValue = null;

Now I have tried to use various combination of the Properties but all the time I get the same result. If you click on the DTP or press the DropDown Button either the minDate is selected or (if not set) 01.01.0001 is selected in the calendar. I have tried to set the value of the DTP to DateTime.Now or setting the NullDate and use the SetToNullValue(); but no matter what the Value will never change and remain as it was (minDate or 01.01.0001).

How can I achieve the desired behaviour?

Any way to make CommandBarSplitButton function like a toggle button?

I've read over this forum post which has a potential solution for RadSplitButton, but I am struggling to apply this to a CommandBarSplitButton.

Basically the behavior I need is:
-when any menu item in the split button is clicked, that item should become the default item AND the button should show a highlighted state like IsMouseOver = true
-when the action button is clicked while it is highlighted, it should un-highlight. (Other "cancel" conditions can cause this as well)

I have tried setting IsMouseOver = true on about every element I could find in the hierarchy. I'd prefer not to have to create a custom theme or change the background colors manually if possible.

We're using Q2 2011 SP1 on our way to Q3 2011.

Thanks,
Adam

Timeline view & horizontal scroll click

I need to detect if the user has clicked the horizontal scrollbar rather than an appointment, cell element, RadSchedulerNavigator or the RadCalendar associated with the RadScheduler.

Have not been able to work out how to attach to the event.

Thanks

RadRibbonBar disable fade animation

Hi,

I'm looking for a way to disable the animation that is used when a user has a collapsed RibbonBarElement (RibbonBarElement.Expanded = false) and then interacts with the RadRibbonTabs. Single clicking a tab in this case opens the tab strip while the tab strip has focus. Once focus has left the control (user clicks elsewhere), the tab strip returns to a collapsed state. When it returns to being collapsed, there is an opacity fade effect being applied. Sometimes when the message pump is busy with other processing going on, this fade effect is looking bad and I can't figure out how to disable it.

Setting AnimatedPropertySetting.AnimationsEnabled = false; does not seem to work in this case. (The particular project I am working with is RadControls WinForms Q1 2010 SP2 - an upgrade is possible in the future for this, but not at this time. I haven't yet been able to investigate whether there is a visible setting in Q3 2011).

If anyone has any insight into how to control this, I'd appreciate it.

Thanks,
Adam
