如何将UIelements设为只读

我需要在Mainwindow顶部显示诸如popup 之类的userconrol，...同时显示我正在破坏所有UI元素，如

I have a requirement to display the userconrol like popup on top of Mainwindow,...while displaying i am disabuling the all UI elements like

foreach(UIElementitem inmodalGrid.Children)

foreach (UIElementitem inmodalGrid.Children)

item.IsEnabled = false;
modalGrid.Children.Add(uc);

item.IsEnabled = false;
modalGrid.Children.Add(uc);

代码工作正常，但是问题是我也要在散布后显示所有UIelements看起来也很正常.它不应该更改颜色(它应该看起来像Readonly)

Code is working fine,but the problem is i want to display all the UIelements looks like normal after disabuling also.it should not change the color(it should looks Like Readonly )

请让我知道是否可以在WPF中更改消失的UIElement的颜色?

Please let me know is it posibule to change the color for disabuled UIElements in WPF ?
