Question

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

Answer 1

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; }
    }
}
