How to: Create Toggle Buttons in ToolStrip Controls
When a user clicks a toggle button, it appears sunken and retains the sunken appearance until the user clicks the button again.
To create a toggling ToolStripButton
Use code such as the following code example. This code assumes that your form contains a ToolStrip control, and that its Items collection contains a ToolStripButton called toolStripButton1. It also assumes that you have an event handler called toolStripButton1_CheckedChanged.
[Visual Basic]
toolStripButton.CheckOnClick = True toolStripButton.CheckedChanged AddressOf _ EventHandler(toolStripButton_CheckedChanged);
[C#]
toolStripButton.CheckOnClick = true; toolStripButton.CheckedChanged += new _ EventHandler(toolStripButton_CheckedChanged);
