Can't use RadSplitButton normally

Hello guys.

I want to add to my app RadSplitButton, but I can't configure it normally. I was looking to example code from telerik how to use this type of buttons. But when I added it to my project with all settings, buttons behavior was diffrenet from the telerik example. Allways when I am pressing on the button in all the places(Arrow button, Action button) the DropDownMenu is opened (the differance is that in the telerik example DropDownMenu opened only when Arrow button pressed).

The 1st question is why example has't all the settings? And I think I am not telling about one property that has be forgotten, because selection of the button in example was modified too.

I tried to find a property that can disable menu popupping, but my attempt was failed.

I found ugly solution:

- Set property DropDownButtonElement.DropDownMenu.PopupElement.Visibility = ElementVisibility.Collapsed

- Add click method to Click Event for DropDownButtonElement.ActionButton, and add to the start of the method this function: DropDownButtonElement.DropDownMenu.Hide()

This solution works fine, but I believe that there is another way to disable menu popup on. Have you guys any ideas?

Virtual GridView + sorting etc.

I'm new to using Kendo and have tried the following example that allows for a GridView in Virtual Mode to have sorting etc.

http://www.telerik.com/support/kb/winforms/gridview/details/high-performance-with-radgridview-and-virtual-mode-including-filtering-sorting-and-grouping

Using the latest version of Kendo with this example, the Grid still throws the 'Operation not supported in Virtual Mode' exceptions.

Has this functionality been changed / broken / replaced? Whilst I have a virtual mode grid working with a large data source through service interfaces using linq incl. paging, I can't even override the header sorting myself without these exceptions being thrown which kind of makes the grid not very useful for paging large result sets. The articles on the subject saying what to do no longer seem to work unless I'm missing something.

No theme for RadDropDownElement in a list?

I am trying to place RadDropDownElement controls in a list by putting them in a stackLayout and overriding CreateVisualElement. That works.

My problem is that the shows up in black and white with no theming whatsoever. The new VisualItem returns ThemeEffectiveType properly, but this is for the contained dropdowns, not the list control itself.

Why are the dropdowns not themed, and how do I correct this?

Placing RadDropDownButtons in a list

I need a control that has a growable list of rows, and I'd like a strip of buttons.

I thought I could just use a RadListView and create my own VisualItems, but I cannot add a RadDropDownButton to it because that control doesn't appear to derive from RadElement.

I really don't want to have to manage scrolling and growth on my own with a RadScrollablePanel, so what's the best way to go about this? All I need is a control that can show a list of strips that contain other controls that happen to include RadDropDownButtons and so on.

So what's the best way to manage a growing list of RadDropDownButton-based objects?

Background Color for GridView

Something so simply yet Telerik seems so un-intuitive.

I want a buttonface background color, but the cells I want white. It seems when I set the background color, it then colors the cells also. That to me seems very un-intuitive. Putting my gripe aside, any idea how to achieve this simply issue?

What does RadMap.MapElement.Wraparound do?

Hello,

I've just started working with RadMap and am trying to figure out what Wraparound does. My goal is to show a graphic in the tile layer and when the user pans all the way to the left side of the graphic, I'd like the pan to stop. Same goes for the right hand side of the graphic. All of your samples seem to wrap around. For example, with Bing maps, I'm centered on Europe -> hold down the pan left button, the map goes all the way around the world and pans to Europe again (and again...). What I'd like to have happen is that the user can pan no further left than Europe, and no further right than say, the Atlantic Ocean. I'm not tied to the BingMapProvider, and am ultimately going to write my own IMapProvider.

Additionally, when I set the Wraparound property in the designer, it doesn't persist.

Thank you.
