ToolStripDropDown.KeyUp ToolStripDropDown.KeyUp ToolStripDropDown.KeyUp ToolStripDropDown.KeyUp Event

Definition

Occurs when a key is released while the control has focus.

public:
 event System::Windows::Forms::KeyEventHandler ^ KeyUp;
[System.ComponentModel.Browsable(false)]
public event System.Windows.Forms.KeyEventHandler KeyUp;
member this.KeyUp : System.Windows.Forms.KeyEventHandler 
Public Custom Event KeyUp As KeyEventHandler 
Attributes

Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the KeyUp 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 type ToolStripDropDown named ToolStripDropDown1. Then ensure that the event handler is associated with the KeyUp event.

private void ToolStripDropDown1_KeyUp(Object sender, KeyEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Alt", e.Alt );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Control", e.Control );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Handled", e.Handled );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "KeyCode", e.KeyCode );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "KeyValue", e.KeyValue );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "KeyData", e.KeyData );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Modifiers", e.Modifiers );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Shift", e.Shift );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "SuppressKeyPress", e.SuppressKeyPress );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "KeyUp Event" );
}
Private Sub ToolStripDropDown1_KeyUp(sender as Object, e as KeyEventArgs) _ 
     Handles ToolStripDropDown1.KeyUp

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "Alt", e.Alt)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Control", e.Control)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Handled", e.Handled)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "KeyCode", e.KeyCode)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "KeyValue", e.KeyValue)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "KeyData", e.KeyData)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Modifiers", e.Modifiers)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Shift", e.Shift)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "SuppressKeyPress", e.SuppressKeyPress)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"KeyUp Event")

End Sub
