Hello Christianto,

Thank you for writing.

After carefully looking at the attached screenshot, it seems that you want to change the background of the ToolWindow popup. Note that when you show an auto-hidden ToolWindow, RadDock displays a RadForm. You can apply the same BackColor as the main form because the controls transparency is a common problem in the whole WinForms. You can find useful information on this topic on the following links:

• http://stackoverflow.com/questions/4387680/transparent-background-on-winforms
• http://stackoverflow.com/questions/14309770/c-sharp-transparent-background-for-window-form

Here is a sample code snippet which achieves the result illustrated on the sample screenshot:

AddHandler Me.RadDock1.AutoHideWindowDisplayed, AddressOf AutoHideWindowDisplayed

Private Sub AutoHideWindowDisplayed(sender As Object, e As DockWindowEventArgs)
    Dim hw As HostWindow = TryCast(e.DockWindow, HostWindow)
    Dim popup As AutoHidePopup = TryCast(hw.ParentForm, AutoHidePopup)
    popup.ToolStrip.BackColor = Me.BackColor
End Sub

I hope this information helps. Should you have further questions, I would be glad to help.
