How to add a histogram on RadSlider based on high and low values.I am attaching the image

Hi,

I am using version 2014.1.224.45 of UI for WPF. I need to make my docking control fill all my client area of its parent UserControl.

If i do not explicitly define a Height I receive the error: "Placing Docking control in a panel or control that measures it with infinite width or height is not supported in the current version."

Is it possible?
How can I do this ?

If the is not really possible which events I must drive to define explicitly the heit as the hight of the parent. I have treid the SizeChanged Event of the parent bit it did not work.

Thanks in advance

How to get compass angle? Is there any function in Telerik library to call and return value?
See image for more info.

Must be OK with negative value too.

If I add items to a VisualizationLayer from c# nothing is displayed. However, it works using the same code with an InformationLayer. What do I need to do to get the VisualizationLayer to work?

Hi Team,
I am using RichTextBox in my project. All they keyboard controls work fine. But I want to give a toggle button for bold, italics and underline, so that the user can click on bold and make the text bold.

Can you please help me in this regard.

I have RadTabControl with RadGridView in the ContentTemplate. I need bind this RadGridView as a command parameter to the button, that is outside the RadTabControl. Is there a way to do that? Looks like such feature is missing in your controls
