I have custom tool strip button
BindableToolStripButton : ToolStripButton
It works well, but I don't know possibility to add this item to control in design menu..
Could I add my BindableToolStripButton to the designer menu?
Add this attribute before your custom BindableToolStripButton class definition
[ToolStripItemDesignerAvailability(ToolStripItemDesignerAvailability.All)]
