        <ObjectAnimationUsingKeyFrames Duration="0" Storyboard.TargetProperty="ToolTipService.ToolTip" Storyboard.TargetName="btn">
          <DiscreteObjectKeyFrame KeyTime="0">
            <DiscreteObjectKeyFrame.Value>
              <System:String>Button is checked</System:String>
            </DiscreteObjectKeyFrame.Value>
          </DiscreteObjectKeyFrame>
        </ObjectAnimationUsingKeyFrames>
      </Storyboard>
    </VisualState>

之前我也遇到过同样的问题。所以，我离开了 VSM。我将工具提示作为资源并将其应用于控件。使用内部状态更改属性，我使用转换器更新了工具提示值。

HTH。
