Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Occurs when the Enabled property value has changed.
public:
event EventHandler ^ EnabledChanged;public event EventHandler EnabledChanged;public event EventHandler? EnabledChanged;member this.EnabledChanged : EventHandler Public Custom Event EnabledChanged As EventHandler Event Type
Examples
The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the EnabledChanged event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.
To run the example code, paste it into a project that contains an instance of a type that inherits from ToolStripItem, such as a ToolStripButton or ToolStripMenuItem. Then name the instance ToolStripItem1 and ensure that the event handler is associated with the EnabledChanged event.
private void ToolStripItem1_EnabledChanged(Object sender, EventArgs e) {
MessageBox.Show("You are in the ToolStripItem.EnabledChanged event.");
}
Private Sub ToolStripItem1_EnabledChanged(sender as Object, e as EventArgs) _
Handles ToolStripItem1.EnabledChanged
MessageBox.Show("You are in the ToolStripItem.EnabledChanged event.")
End Sub
Remarks
This event is raised if the Enabled property is changed by either a programmatic modification or user interaction.
Note
Changing the Enabled property of a ToolStrip does not raise the EnabledChanged event. Raise this event with specific property settings.
