just noticed that a C1SplitButton does not look very beautiful with the theme “Office2010Black”: the image bar of the ContextMenuStrip dropdown has still light gray background:
See attached sample. SplitButtonThemed.zip
This is probably a limitation of the ContextMenuStrip. But it seems there is a workaround: c# - ContextMenuStrip icon transparency - Stack Overflow =>Set “ContextMenuStrip.RenderMode” to “ToolStripRenderMode.System”. My sample contains another control with a ContextMenuStrip (not shown in the screenshot), and here I can confirm that this workaround works. But I don’t know whether it has other side effects on the C1SplitButton. What do you think about this?
