复选框错误隐藏文本框 [英] Checkbox false hide textbox

问题描述

我知道这是一个简单的问题，但是我已经离开编程界三年了，所以请帮忙！

如果我在WPF页面上有一个复选框，如果未选中该复选框，如何隐藏文本框?

在此先感谢

I know this is an easy question, but I have been out of the programming world for 3 years so please help!

If I have a checkbox on a WPF Page how do I hide a textbox if the checkbox is not ticked?

Thanks in advance

推荐答案

嘿，

您可以将Textbox的Visibility属性绑定到CheckBox的Checked属性，并使用BooleanToVisibilityConverter来使类型匹配.那应该做.
让我知道是否需要进一步说明.

Hey,

You can bind the Textbox''s Visibility property to the CheckBox''s Checked property and use a BooleanToVisibilityConverter to make the types match. That should do it.
Let me know if you need more clarity.

好，这是一个示例窗口，其中包含了我认为您要的内容.当您单击复选框时，该文本块将变为可见.


< Window x:Class ="WpfFrontEnd.Window4"
xmlns ="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x ="http://schemas.microsoft.com/winfx/2006/xaml"
Title ="Window4" Height ="300" Width ="300">
< Window.Resources>

< BooleanToVisibilityConverter x:Key ="boolToVisible"/>

</Window.Resources>
< Grid>

< StackPanel>
< CheckBox x:Name ="CheckBox1"/>
< TextBlock Visibility ="{Binding ElementName = CheckBox1，Path = IsChecked，Converter = {StaticResource boolToVisible}}">你好</TextBlock>
</StackPanel>

</Grid>
</Window>

Ok here is a sample window with what I think you are asking for. When you click the checkbox, the textblock becomes visible.


<Window x:Class="WpfFrontEnd.Window4"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window4" Height="300" Width="300">
<Window.Resources>

<BooleanToVisibilityConverter x:Key="boolToVisible"/>

</Window.Resources>
<Grid>

<StackPanel>
<CheckBox x:Name="CheckBox1"/>
<TextBlock Visibility="{Binding ElementName=CheckBox1, Path=IsChecked, Converter={StaticResource boolToVisible}}">Hello</TextBlock>
</StackPanel>

</Grid>
</Window>
