WPF simple tips-and-tricks? [closed]

Answer 1

Provide a unique row or column for a GridSplitter to ensure that it is not hidden by other controls and behaves as expected.

Answer 2

Set a property in Code Behind to a DynamicResource:

Border_Toolbar.SetResourceReference(BackgroundProperty, "Brush_ToolbarBackground")

Answer 3

IsMouseOver and IsMouseDirectlyOver are different events. IsMouseOver responds to all mouse movement within a control and it's children. IsMouseDirectlyOver responds only if the cursor is over the control itself. For instance, if you have a label contained within a border, the IsMouseDirectlyOver event for the Border only fires if the cursor is over the Border itself but NOT over the contained Label.
