hi
我正面临在需要时获取滚动条的问题(控件溢出).我正在wpf中动态创建控件，iam使用控件平移作为画布.我让滚动条达到极限，而我的控件超出极限，
我曾在xaml中尝试过此代码，
我要去哪里了，请引起您的注意

非常感谢您的关注

推荐答案

您好sivakumarmr10，

您发布的代码包含一个小错误，因为Canvas控件应以大写字母"C"开头.除此之外，基本想法似乎还不错.

以下代码段应在Visual Studio中呈现:

Hi sivakumarmr10,

The code you posted contained a small error in that the Canvas control should begin with a capital ''C''. Other then that the basic idea seemed fine.

The following code snippet should render in Visual Studio :

<Window

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

Title="Window1" Height="300" Width="300">
<ScrollViewer>
    <Canvas Width="10" Height="10">
        <Button Height="15" Width="15" Background="Red"/>
    </Canvas>
</ScrollViewer>
</Window>

至于动态添加控件，您可能会发现WrapPanel更适合您的需求.根据您使用的控件类型，我可能会建议您发现一种更有用的方法，但我需要更多信息.

我不确定这是否是您的意图，但您可能还想避免明确定义控件的Width和Height以及Canvas位置，因为这可能会导致可伸缩性问题.

As for dynamically adding controls, you might find that a WrapPanel would suit your needs better. Depending on the type of Controls that you use I could suggest a method you might find more helpful, but I would need more information.

I''m not sure if it was your intention but you may also want to avoid explicitly defining the Width and Height of the controls as well as the Canvas position, as this may cause scalability issues.
