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.

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.

toolStripButton1.CheckOnClick = True toolStripButton1.CheckedChanged AddressOf _ EventHandler(toolStripButton1_CheckedChanged);[C#]
toolStripButton1.CheckOnClick = true; toolStripButton1.CheckedChanged += new _ EventHandler(toolStripButton1_CheckedChanged);
