如何使Windows窗体控件只读？ [英] How do I make a Windows Forms control readonly?

问题描述

返回到VS2008中的WinForms很长一段时间以后。在VS2008速成版OOD的问题修修补补。

Returning to WinForms in VS2008 after a long time.. Tinkering with a OOD problem in VS2008 Express Edition.

我需要一些控制是只显示部件。用户不应该能够改变这些控件的值...小部件是由周期性的更新Tick事件进行更新。我依稀记得那里是你可以设置有此行为的只读属性......现在不能找到它。

I need some controls to be "display only" widgets. The user should not be able to change the value of these controls... the widgets are updated by a periodic update tick event. I vaguely remember there being a ReadOnly property that you could set to have this behavior... can't find it now.

在已启用属性设置为false：灰色了控制内容。我想控制到正常观看。
中的锁定属性设置为false：似乎是保护意外扭曲在Visual窗体设计器控制用户

The Enabled property set to false: grays out the control content. I want the control to look normal. The Locked property set to false: seems to be protecting the user from accidentally distorting the control in the Visual Form Designer.

我在想什么？

这也是一个很好的提示保存的外观：

This is also a good tip to preserve the appearance:

    textBox1.ReadOnly = true;
    textBox1.BackColor = clr;
