How to hide the tool panel on the left in RadImageEditor?

Hi,

You can add a ZoomController to your view and bind it to the RadImageEditor in it to allow zoom in/out functionality like the one in RadImageEditorUI.

<telerik:radimageeditor name="imageEditor" xmlns:telerik="#unknown">
<imaging:zoomcontroller grid.row="1" imageeditor="{Binding ElementName=imageEditor}" margin="0 8" xmlns:imaging="#unknown">
The imaging namespace should be defined as follows:
xmlns:imaging="clr-namespace:Telerik.Windows.Media.Imaging;assembly=Telerik.Windows.Controls.ImageEditor"

Alternatively, you can adopt implicit styles in your application and modify the default style of RadImageEditorUI to fit your needs.

I hope this helps.
