Mouse.Capture Method (IInputElement, CaptureMode)
Captures mouse input to the specified element using the specified CaptureMode.
Assembly: PresentationCore (in PresentationCore.dll)
The element to capture the mouse.
The capture policy to use.
Return ValueType: System.Boolean
true if the element was able to capture the mouse; otherwise, false.
When an element captures the mouse, it receives mouse input whether the cursor is within its borders.
To release mouse capture, call Capture passing null as the element to capture.
If the mouse is captured when a MouseDown or MouseUp event is raised and the input is not going to the element underneath the mouse, PreviewMouseDownOutsideCapturedElement and PreviewMouseUpOutsideCapturedElement are raised first. This enables the captured element a chance to release capture before the MouseDown and MouseUp events are routed.
