无法设置RibbonTextBox isEnable为False [英] Cannot set RibbonTextBox isEnable to False

问题描述

我一直在尝试了功能区控件，并经历了一个可能的错误（或我做错了什么也许）。如果我有一个 RibbonTextBox 在 RibbonTab ，并设置在 isEnabled 为假或真在后面的代码，我只能将它设置为false，但不是真正的。在 RibbonTextBox 依然被禁用。

  / *在我的XAML * / 
<丝带：RibbonTextBox X：NAME =实时出价标签=Button1的/> 
 
 / *后面* / $ B $我的代码为B rtb.IsEnabled = FALSE; // RibbonTextBox被禁用并呈灰色
 ...一些其他的代码... 
 rtb.IsEnabled = TRUE; // RibbonTextBox保持禁用并呈灰色
  

解决方案

Apperently，这是一个已知的问题。

的 RibbonTextBox IsEnabled属性始终为false

I have been trying out the Ribbon Controls and experienced a possible bug (or I am doing something wrong perhaps). If I have a RibbonTextBox on the RibbonTab, and setting the isEnabled to False or True in code behind, I can only set it to false but not the true. The RibbonTextBox remain to be disabled.

/* in my XAML */
<ribbon:RibbonTextBox x:Name="rtb" Label="Button1" />

/* in my code behind */
rtb.IsEnabled = false;  // RibbonTextBox is disabled and grayed out
... some other code ...
rtb.IsEnabled = true;   // RibbonTextBox remain disabled and grayed out

解决方案

Apperently, this is a known issue

RibbonTextBox IsEnabled property is always false

A possible workaround is also given at that link
Update: I tried this workaround myself and it does indeed work

public class FixedRibbonTextBox : RibbonTextBox
{
    protected override bool IsEnabledCore
    {
        get { return true; }
    }
}
