ToolStripDropDown Class

Represents a control that allows the user to select a single item from a list that is displayed when the user clicks a ToolStripDropDownButton. Although ToolStripDropDownMenu and ToolStripDropDown replace and add functionality to the Menu control of previous versions, Menu is retained for both backward compatibility and future use if you choose.

Use the ToolStripDropDown to display drop-down lists of options, such as a color picker.

The following code example uses the ToolStripDropDown and ToolStripDropDownButton classes to make a three-button color picker that changes the foreground color of the form.

		// Declare the drop-down button and the items it will contain. 
		internal ToolStripDropDownButton dropDownButton1;
		internal ToolStripDropDown dropDown;
		internal ToolStripButton buttonRed;
		internal ToolStripButton buttonBlue;
		internal ToolStripButton buttonYellow;


		private void InitializeDropDownButton()
		{
			dropDownButton1 = new ToolStripDropDownButton();
			dropDown = new ToolStripDropDown();
			dropDownButton1.Text = "A";

			// Set the drop-down on the ToolStripDropDownButton.
			dropDownButton1.DropDown = dropDown;

            // Set the drop-down direction.
            dropDownButton1.DropDownDirection = ToolStripDropDownDirection.Left;

            // Do not show a drop-down arrow.
            dropDownButton1.ShowDropDownArrow = false;

			// Declare three buttons, set their foreground color and text,  
			// and add the buttons to the drop-down.
			buttonRed = new ToolStripButton();
			buttonRed.ForeColor = Color.Red;
			buttonRed.Text = "A";

			buttonBlue = new ToolStripButton();
			buttonBlue.ForeColor = Color.Blue;
			buttonBlue.Text = "A";

			buttonYellow = new ToolStripButton();
			buttonYellow.ForeColor = Color.Yellow;
			buttonYellow.Text = "A";
			
			buttonBlue.Click += new EventHandler(colorButtonsClick);
			buttonRed.Click += new EventHandler(colorButtonsClick);
			buttonYellow.Click += new EventHandler(colorButtonsClick);

			dropDown.Items.AddRange(new ToolStripItem[] 
				{ buttonRed, buttonBlue, buttonYellow });
			toolStrip1.Items.Add(dropDownButton1);
		}


		// Handle the buttons' click event by setting the foreground color of the 
		// form to the foreground color of the button that is clicked. 
		private void colorButtonsClick(object sender, EventArgs e)
		{
			ToolStripButton senderButton = (ToolStripButton)sender;
			this.ForeColor = senderButton.ForeColor;
		}
