    I find the crop feature really anoying.

    you click crop then draw a box, then press enter to crop it.... thats not how image editing works.

    if your cursor is over the image you should be able to draw a box then click crop and have it crop to that area...

    or have it so when you click crop you get a overlay dialog with a 'crop' button as its not really user friendly on how to do this.

    Is there a way to override the crop button so that when you click it a button appears to 'confirm'. That way the user knows how to actually crop the image?

    A suggestion i can make for future improvement is take a look at Easypainter as its silverlight image editing and its amazing. unfortunately its written in SL3 and you cant get the code but still it show much better functionality.

    Thank you for your feedback. We don't plan on changing the behavior of the crop tool, but you can implement a crop tool with the desired behavior.
    When adding the crop button to RadImageEditorUI, it will look something like that in XAML:
    <telerik:ImageToolItem ImageKey="Crop" Text="Crop"  Command="commands:ImageEditorRoutedCommands.ExecuteTool">
            <tools:CropTool />
    Here, you can see the reference to the built-in CropTool. You can create your custom tools as described in this article: http://www.telerik.com/help/silverlight/radimageeditor-features-commands-and-tools.html .
    In your custom tool, you can wrap the default functionality, adding your own tweaks or build the tool yourself to achieve maximum flexibility.
    Let us know if you experience any other issues.
