網格 - 隱藏的行和文本塊顯示問題

我有一個簡單的對話框 - A Grid與4 TextBlock的其中我綁定了第二個和第三個TextBlock的屬性的可見性，但它不像預期的那樣工作，即，條件消息在查看對話框時顯示爲截斷。該對話框的2種變體是如下：網格 - 隱藏的行和文本塊顯示問題

某些文本

條件消息1

或

某些文本

條件消息2

B C

該對話框的XAML如下所示。

你有幾個RowDefinition的地方有一個錯誤的高度（你應該刪除這部分）

Height="{Binding TransactionsModified, Converter={StaticResource booleanToVisibilityConverter}}">

當然直接結合高度爲BOOL中是沒有意義的：你已經有了更多在以下部分合理觸發（他們一見鍾情）
