Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the GotFocus event. This report helps you to learn when the event occurs and can assist you in debugging.

To run the example code, paste it into a project that contains an instance of type HtmlWindow named HtmlWindow1. Then ensure that the event handler is associated with the GotFocus event.

private void HtmlWindow1_GotFocus(Object sender, HtmlElementEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "MouseButtonsPressed", e.MouseButtonsPressed );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ClientMousePosition", e.ClientMousePosition );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "OffsetMousePosition", e.OffsetMousePosition );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "MousePosition", e.MousePosition );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "BubbleEvent", e.BubbleEvent );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "KeyPressedCode", e.KeyPressedCode );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "AltKeyPressed", e.AltKeyPressed );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "CtrlKeyPressed", e.CtrlKeyPressed );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ShiftKeyPressed", e.ShiftKeyPressed );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "EventType", e.EventType );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ReturnValue", e.ReturnValue );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "FromElement", e.FromElement );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ToElement", e.ToElement );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "GotFocus Event" );
}

     Handles HtmlWindow1.GotFocus

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "MouseButtonsPressed", e.MouseButtonsPressed)

Remarks

GotFocus will occur for:

The first window in a FRAMESET when the FRAMESET first loads.
The FRAME that last had focus when the window containing the WebBrowser control is brought to the foreground.
A FRAME clicked by the user, but only if the user's click does not put focus on an element within the window.

You cannot cancel the default action for the GotFocus event, or prevent it from bubbling.
