RadioButton.Checked错误：Control.Checked不能出现在+ =或左手边 - = [英] RadioButton.Checked Error: Control.Checked cannot appear on the left hand side of += or -=

问题描述

我有奇怪的问题，我必须失去了一些东西。

I am having the strangest problem, and I have to be missing something.

下面是我的代码导致错误。

Here is my code that is causing the error.

if (radLot.Checked == true)
{
    SymbolSpecification = "LotRenderer";
}

if (radWaterMeter.Checked == true)
{
    SymbolSpecification = "WaterMeterRenderer";
}

正如你所看到的，我甚至不使用= +或 - = ......我居然没有在我的代码的任何地方...任何帮助，将不胜感激。

As you can see, I don't even use =+ or -=... I actually don't have it anywhere in my code... Any help would be appreciated.

推荐答案

<一个HREF =htt​​p://msdn.microsoft.com/en-us/library/system.windows.controls.primitives.togglebutton.checked相对=nofollow> 经过 是当一个切换按钮被选中时引发事件的名称。 （在单选类从切换按钮派生的。）

Checked is the name of the event that is raised when a ToggleButton is checked. (The RadioButton class derives from ToggleButton.)

我假设你要访问的 器isChecked 属性，该属性获取（或设置）是否切换按钮被选中。

I assume you want to access the IsChecked property, which gets (or sets) whether the ToggleButton is checked.

if (radLot.IsChecked == true)
{
    SymbolSpecification = "LotRenderer";
}
