感謝您閱讀我的問題！
我有一個自定義DataGrid RowGroupHeader的問題，情況是：
我需要一種控制DataGrid RowGroupHeader的方式，因爲我想在其中顯示一些數據綁定值。這些值將在運行時生成，因此需要在運行時生成RowGroupHeaderStyle並將其添加到DataGrid的RowGroupHeaderStyles屬性中（可能使用XamlReader.Load）。
此外，RowGroupHeader內的數據綁定值的位置應與DataGrid中的相應列對齊。
我已經成功地創建一個使用這個帖子MS Forum工作模板，但我曾與定位數據綁定的元素，在我的情況的TextBlock沒有運氣，正確地與給定的DataGrid列對齊。
有什麼建議嗎？
非常感謝如何爲Silverlight 3自定義DataGrid RowHeaderGroup創建模板？
這不是一項容易的，但是經過一番廣泛的谷歌搜索和拼湊了其他人的經驗，我想出了這一點，做工精細，我

在這一點上我在網格中有一些動態列，所以我現在就像Grid.ColumnDefinitions一樣添加它們，但是如果你的數據網格是靜態的，那麼你就把正確數量的列放入。

這是你的內容進來，再次我有一些動態列，所以我需要動態地添加細胞（無需這樣做，如果您的網格是靜態的）
<data:DataGridCell Content=""{Binding Name}""/>
<data:DataGridCell Content=""""/>
<data:DataGridCell Content=""""/>
<data:DataGridCell Content=""""/>
<data:DataGridCell Content=""""/>
<data:DataGridCell HorizontalContentAlignment=""Left"" Margin=""7,0,0,0"" Content=""{Binding Converter={StaticResource myConverter}, ConverterParameter=TotalScore}""/>" + colStr2 +
那是非常多的，是的，我同意這不是一項簡單的工作，但它可以讓你在需要時自定義風格！歡迎評論！
忘了添加到這個：在運行時使用XamlReader.Load加載樣式（在我的情況下）或者將它作爲ResourceDictionary或類似的XAML – KlsLondon 2010-11-12 15:49:49
您可以展開__Row__頭中的內容如何與特定的__Column__對齊嗎？你的意思是垂直的嗎？這是非常高的順序。還有一些原因標題綁定的行標題中的內容將無法正常工作？或者你是否說要顯示的潛在綁定集可能會每行有所不同？ – AnthonyWJones 2010-10-01 10:04:11
