禁用文本框时复选框时在C＃中运行时未选中 [英] Disable text box when Check box is Unchecked during run time in C#

问题描述

我有一个复选框和一个TextBox。在运行时，结果
如果复选框被选中，然后文本框被启用。

我就用下面的代码

 私人无效checkTime_Checked（对象做发件人，RoutedEventArgs E）
 {
如果（checkTime.IsChecked ==真）
 {
 txtTime_SR.IsEnabled = TRUE; 
} 
} 
  

我需要做的是，要禁用文本框当复选框运行期间未选中。

这样做呢？

解决方案

读您的文章和评论，我会想你正在做WPF或Silverlight。
然后，在这种情况下，你可能会做这一切在XAML：

 <复选框X：NAME = checkTime/> 
<文本框X：NAME =txtTime_SRIsEnabled ={结合器isChecked，的ElementName = checkTime，转换器= {StaticResource的NotConverter}，模式=单向}/> 
  

然后，你需要创建转换器。这可以通过在这里阅读后完成：如何绑定逆布尔属性WPF？

I have a CheckBox and a TextBox. During the runtime,
if the CheckBox is Checked then the TextBox is enabled.

I did it using following code

private void checkTime_Checked(object sender, RoutedEventArgs e)
{
    if (checkTime.IsChecked == true)
    {
        txtTime_SR.IsEnabled = true;
    }
}

What I need to do is, to disable the TextBox when the CheckBox is Unchecked during runtime.

Any idea of doing this ?

解决方案

Reading your post and comments, I'll guess you are doing WPF or silverlight. Then, in that case, you may do it all in XAML :

<CheckBox x:Name="checkTime" />
<TextBox x:Name="txtTime_SR" IsEnabled="{Binding IsChecked, ElementName=checkTime, Converter={StaticResource NotConverter}, Mode=OneWay}"/>

Then, you need to create the converter. This can be done by reading post here : How to bind inverse boolean properties in WPF?
