I am using the MS Toolstrip control and would like to add a label that is bound to a datasource. Is this possible? And if so how is it done?
I do not believe it's possible.
DataBinding is defined in System.Windows.Forms.Control. The Toolstrip items (System.Windows.Forms.ToolStripItem) are no controls theirselves. They inherit from the Component.
So you need to code that manually (using the PositionChanged event handler etc., using the InputValue, ...).
