在WPF中以编程方式将AutomationId分配给模板控件

Question

I've got a control template that looks like:

<Style TargetType="Thumb">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate>
                <Ellipse Fill="{TemplateBinding Background}"></Ellipse>
            </ControlTemplate>
        </Setter.Value>
    <Setter>
</Style>

I've been able to create a setter tag to assign an automationid to the instantiated objects. But as one would expect all of the controls have the same ID.

There's some further XAML that defines 3 thumbs (center, left, and right), I'm wanting to define their IDs in such a way that they would like:

Center_1 Right_1 Left_1

Center_2 Right_2 Left_2

Any ideas on how I can make this happen?

I'm guessing I would need to have a static member variable to track the number of instantiated objects (and then use that to increment the name value), but beyond that I'm at a loss.

Thanks in advance!

Uid属性应该是您需要设置的属性。
