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

Month Picker

Hi,

is it possible to change the date/time picker into a year/month picker? I noticed you can do this very easily with the WPF DateTimePicker but cannot see a way to do this on the winforms

thanks

Theming don't work properly

Hi,

after switching to the SP2 (2010.1.10.504) I have a lot problems using themes. When I add the Office black theme and start my application I get two errors that resources are missing (TabOffice12Shape and another one). When I add the Office 10 theme and start the application I get a System.ArgumentException "Specified resource does not exist.". This only happens when I start the application without debugging. If I use the debugger, it works fine. So I think there is a major timing problem when themes are loaded. My I solution is now to remove the Telerik controls and switch back to normal Windows Forms controls.

Hi,

I have a RadGridVIew with a GridViewTextBoxColumn with AcceptsReturn, Multiline, WrapText properties set to true.
When the user hits the return key after typing in a line in this column, I want the row height to increase. This way they can see what they have already typed in and continue typing in.

I have set AutoSizeRows property on the RadGridView to true but this takes affect after editing the cell is finished.

Please help in this regard.
