ComboBox.OnMouseLeftButtonDown Method

Silverlight

Provides handling for the MouseLeftButtonDown event that occurs when the left mouse button is pressed while the mouse pointer is over the combo box.

Namespace:  System.Windows.Controls
Assembly:  System.Windows (in System.Windows.dll)

protected override void OnMouseLeftButtonDown(
	MouseButtonEventArgs e
)

Parameters

e
Type: System.Windows.Input.MouseButtonEventArgs
The event data.

The OnMouseLeftButtonDown method is called before any event handler for the MouseLeftButtonDown is called. This method allows derived classes to handle the MouseLeftButtonDown event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

This implementation marks the MouseLeftButtonDown event as handled by setting the Handled property of the event data to true. In addition, this implementation sets the IsDropDownOpen property to true.
