我有一个带有几个复选框的WPF应用程序。我可以在XAML中设置IsChecked属性,但是,当我以编程方式设置它时,没有这样的属性。从我读到的所有内容来看,这个属性(IsChecked)就是我应该如何设置值。
XAML如下:
<Window x:Class="FC.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

<KeyBinding Key="L"

Command="ApplicationCommands.PrintPreview" />
<KeyBinding Key="I"

if (Regex.Matches(alarm1Data.ToString(), "ALARM 1 DISABLED").Count == 1)
{
spAlarm1.IsEnabled = false;
// ckbAlarm1.IsChecked = false; // <--- property not found
}

答案 0 :(得分:3)
<Label Name ="ckbAlarm1" FontWeight="Bold">Alarm 1</Label>
ckbAlarm1是LABEL !!
答案 1 :(得分:0)
我正在使用Microsoft Visual C#2010 Express并遇到了同样的问题,但使用了不同的解决方案。该平台的正确代码是:
this.checkBoxDebugMode.Checked = World.Setup.Debug;
而不是
this.checkBoxDebugMode.IsChecked = World.Setup.Debug;
IsChecked
在这里不是有效的属性,但它是您在查找时找到的内容。
