Size:

The size of the control, up to the maximum specified by constraint.

OnApplyTemplate()

When overridden in a derived class, is invoked whenever application code or internal processes call ApplyTemplate().

public override void OnApplyTemplate()

OnCreateAutomationPeer()

Returns class-specific AutomationPeer implementations for the Windows Presentation Foundation (WPF) infrastructure.

protected override AutomationPeer OnCreateAutomationPeer()

Returns

AutomationPeer:

The type-specific AutomationPeer implementation.

Refresh()

Refreshes the control, such as when an external change is made to ActiveBrush that is unable to be detected.

public void Refresh()

RemoveSelectedStop()

Removes the selected gradient stop.

public void RemoveSelectedStop()

ReverseStops()

Reverses the gradient stops in the ActiveBrush.

public void ReverseStops()

Remarks

Gradient stops at offset 1.0 will be moved to offset 0.0 gradient stops at offset 0.0 will be moved to offset 1.0. Gradient stops at offset 0.5 will not be changed.
