CheckState

One of the CheckState values. The default is Unchecked.

Remarks

Use the CheckState property to control or determine whether a ToolStripMenuItem is initially checked, unchecked, or in an indeterminate state.

Starting with the .NET Framework 4.5.2, if the CheckState property is set to Checked or Indeterminate, the corresponding icon may be resized. Resizing is determined by the system DPI setting when the app.config file contains the following entry:

<appSettings>  
  <add key="EnableWindowsFormsHighDpiAutoResizing" value="true" />  
</appSettings>
