Silverlight DataGrid無法伸縮以容納數據源中的所有項目？

Question

我有問題讓Silverlight DataGrid伸展來容納它的dataSource中的所有項目。 我有一個包含兩個DataGrid的網格。 我試着在Grid和DataGrid上設置height = Auto。 我試着在Grid和DataGrid上設置Horizo​​ntalContentAlignment =「Stretch」。 對象標籤有height =「100％」 我已經在Grid的RowDefinitions上設置了Height =「*」

任何幫助將非常感謝！

你似乎有過量RowDefinitions，你是不是分配什麼Grid.Row="1"的。也許你應該消除這一行，並調整你的元素的Grid.Row分配。我還建議您將最後一個RowDefinition的高度設置爲Auto，並從外部網格中刪除Height="Auto"。
