You can place just about anything on the toolstrip.
First (in the IDE) place the desired component on the form (anywhere will do).
Provide yourself with a ToolStripControlHost type variable.
Then when the form in instantiated, do this:

C# Syntax (Toggle Plain Text)

 
private ToolStripControlHost dtTScomponent;
 
public form1()
{
            InitializeComponent();
            dtTScomponent = new ToolStripControlHost(dtMyDateTimePicker);
            MainToolStrip.Items.Add(dtTScomponent); 
}

private ToolStripControlHost dtTScomponent; public form1() { InitializeComponent(); dtTScomponent = new ToolStripControlHost(dtMyDateTimePicker); MainToolStrip.Items.Add(dtTScomponent); }

dtMyDateTimePicker is the component you dropped on the form, and eventually want to live on the tool strip. The hosting variable is instantiated and takes dtMyDateTimePicker as its child. When the new host is added to the toolstrip, the datetime picker goes with it.
You can set the properties of the toolstrip collection and the dtTScomponent properties to get the desired appearance. From that point on, you do not need to refer to the dtTScomponent for anything... it is just a host.
