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