Disable text box when Check box is Unchecked during run time in C#
提问by Zarco
I have a CheckBox and a TextBox. During the runtime,
if the CheckBox is Checked then the TextBox is enabled.
我有一个复选框和一个文本框。在运行时，
如果选中 CheckBox，则启用 TextBox。
I did it using following code
我使用以下代码做到了
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.
我需要做的是，在运行时未选中 CheckBox 时禁用 TextBox。
Any idea of doing this ?
有没有这样做的想法？

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 :
阅读您的帖子和评论，我猜您正在使用 WPF 或 Silverlight。然后，在这种情况下，您可以在 XAML 中完成所有操作：
<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?
然后，您需要创建转换器。这可以通过阅读此处的帖子来完成：How to bind inverse boolean properties in WPF?
Hope it helps

If I understand, you want the textbox to be enabled when the checkbox is checked, and for it to be disabled when the checkbox is unchecked?
如果我理解，您希望在选中复选框时启用文本框，并在未选中复选框时禁用它？
private void checkTime_Checked(object sender, RoutedEventArgs e)
{
txtTime_SR.Enabled = checkTime.Checked;
}
Are you using the standard .NET TextBoxand CheckBoxcontrols?
您使用的是标准的 .NETTextBox和CheckBox控件吗？
EDIT: Ok, so it is WPF. Do this:
编辑：好的，所以它是 WPF。做这个：
private void checkTime_Checked(object sender, RoutedEventArgs e)
{
txtTime_SR.IsEnabled = checkTime.IsChecked;
}

Even simpler
更简单
<CheckBox Content="Include the following..." IsChecked="{Binding IncludeMyItems}" Name="checkBox_includeMyItems" />
<TextBox Name="myItems" Text="{Binding MyItems}" Height="23" Width="165" IsEnabled="{Binding IsChecked, ElementName=checkBox_includeMyItems}" />回答by andy
private void checkTime_Checked(object sender, RoutedEventArgs e)
{
txtTime_SR.Enabled = checkTime.Checked;
}
OR
或者
private void checkTime_Checked(object sender, RoutedEventArgs e)
{
txtTime_SR.IsEnabled = checkTime.IsChecked;
}

I know this is an old post, however this should work. Use the Checked/Unchecked events.
我知道这是一个旧帖子，但是这应该有效。使用选中/未选中事件。
private void checkbox_otherflag_Unchecked(object sender, RoutedEventArgs e)
{
this.textbox_otherflagtext.IsEnabled = false;
}
private void checkbox_otherflag_Checked(object sender, RoutedEventArgs e)
{
this.textbox_otherflagtext.IsEnabled = true;
}
