StringFormat in GroupBox header binding doesn't seem to work

Question

I'm trying to bind the header text of aGroupBox to a property and display it using StringFormat.

The first part works and it returns the text as expected. But I want the final text to be formatted. For example when I return cm I want it to be displayed as Foundation Height (cm), but the code below only shows cm.

<GroupBox Header="{Binding CurrentTargetUnit, 
    Converter={StaticResource QuantityToTextConverter},
    ConverterParameter={x:Static enumerations:Quantity.Length},
    StringFormat='Foundation Height ({0})'}">
</GroupBox>

Answer 1

Try without quotes

....
StringFormat=Foundation Height ({0})}">

UPDATE

As you have used binding for header you should use HeaderStringFormatinstead.

....
HeaderStringFormat=Foundation Height ({0})}">

Read the documentation for more

Answer 2

Try this instead:

StringFormat={}Foundation Height ({0})}">

Answer 3

我有同样的问题。我找到了答案here。

If ibasic Like "A1*" Or ibasic Like "A2*" Or ibasic Like "A3*" Or ibasic Like "A4*" Or ibasic Like "A5*" Or ibasic Like "A6*" Or ibasic Like "A7*" Or ibasic Like "A8*" Or ibasic Like "B1*" Or ibasic Like "B2*" Or ibasic Like "B3*" Or ibasic Like "B4*" Or ibasic Like "B5*" Or ibasic Like "B6*" Or ibasic Like "B7*" Or ibasic Like "B8*" Or ibasic Like "F1*" Or ibasic Like "F2*" Or ibasic Like "F3*" Or ibasic Like "F4*" Or ibasic Like "F5*" Or ibasic Like "F6*" Or ibasic Like "F7*" Or ibasic Like "F8*" Or ibasic Like "C1*" Or ibasic Like "S1*" Then

您还需要从StringFormat中删除引号。另外，在上面的链接中，它显示了在StringFormat中的任何内容之前放置“ {}”。如果我没记错的话，只需要占位符在第一位即可：StringFormat = {} {0：C}

允许StringFormat绑定的元素数量有限，TextBlock为一个，而GroupBox标头则不允许。
