## Description

How to resolve ArgumentException with message "The provided DependencyObject is not a context for this Freezable.", when using RadGauge controls.

## Solution

This can happen in a scenario with multiple gauge controls with animated indicators (like the [Needle](https://www.telerik.com/products/wpf/documentation/controls/radgauge/features/indicators/needle) element) that are updated very fast at runtime (on a small time interval). To resolve this, disable the animation of the indicators. To do this set their **IsAnimated** property to False.

```XAML
	<telerik:Needle IsAnimated="False" /> 
```
