    How can I highlight RadSplitButton to make it more visible  when focused. I tried setting up explicitly IsMouseOver = true on focus enter event, but it doesn't work. Is there any other way I can do it?

    Thanks.

    Hello Alex,

    Thank you for writing.

    You can use a FocusPrimitive in order to notify your users when the button gets focused. Here is an example:
    FocusPrimitive focus;
     
    public Form1()
    {
        InitializeComponent();
     
        BorderPrimitive border = new BorderPrimitive();
        border.ForeColor = Color.Red;
     
        focus = new FocusPrimitive(border);
        splitButton.DropDownButtonElement.Children.Add(focus);
        splitButton.GotFocus += new EventHandler(splitButton_GotFocus);
        splitButton.LostFocus += new EventHandler(splitButton_LostFocus);
    }
     
    void splitButton_LostFocus(object sender, EventArgs e)
    {
        focus.Visibility = ElementVisibility.Collapsed;
    }
     
    void splitButton_GotFocus(object sender, EventArgs e)
    {
        focus.Visibility = ElementVisibility.Visible;
    }

    Feel free to customize the BorderPrimitive according to your needs.
