在运行时/生成时访问controlTemplate元素 [英] Access a controlTemplate element at runtime/generation

问题描述

我有以下ControlTemplate:

Hi, I have the following ControlTemplate:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <ControlTemplate x:Key="ComponentTemplate" x:Name="componentTemplate">
        <Border BorderBrush="Black" BorderThickness="2,2,2,2" Width="104" Height="44" CornerRadius="8,8,8,8">
            <Canvas>
                <Rectangle Name="tplRect" Width="100" Height="40" Fill="LightCyan" RadiusX="8" RadiusY="8" />
                <TextBox Name="tplTextBox"  Text="Component" HorizontalAlignment="Center" Margin="17,10"/>
            </Canvas>
        </Border>
    </ControlTemplate>
</ResourceDictionary>

我希望能够使用C#代码访问文本框，我该怎么做?

I want to be able to access the textbox in C# code, how would I go about doing that?

推荐答案

用TextBox?您愿意访问它的Text值非常简单，只需要将其绑定到类的属性上即可.

That depends, what are you willing to do with the TextBox? With you are willing to access the Text value of it its fairly simple, you only need to bind it to a property from a class.

如果您愿意访问它的其他属性，我将创建一个标记为TextBox的附加属性，以便在其他地方使用，因此在TextBox中，您将添加AP，在PropertyChangedCallback中，添加自定义保持引用的逻辑.

If you are willing to access other properties of it, I would create an attached property that mark the TextBox for use elsewhere, so in the TextBox you would add the AP and in the PropertyChangedCallback add a custom logic to keep the reference to it.

希望这会有所帮助，如果没有告诉我，我会尽力帮助您.

Hope this helps, if doesn''t tell me and I will try to help you out.

一切顺利
