與其他人一樣,我有一個DataGrid沒有顯示滾動條。我認爲我的情況是獨一無二的,我在視覺或邏輯樹中的任何地方都看不到StackPanel。我正在使用WPF Inspector查看樹。我嘗試了各種建議來設置包含網格列和行的高度和寬度,但沒有成功。我敢肯定,我錯過了一些讓內容延伸到可見區域之外的東西,但我不知道它到底是什麼。任何幫助,將不勝感激。此應用程序是一個帶有MEF應用程序的WPF Prism,DataGrid位於Prism區域中的UserControl內。WPF DataGrid不顯示滾動條和用盡可見區域

這確實解決了我的問題。謝謝安德魯。我可以發誓我嘗試了這一點。對不起,發佈這樣一個明顯的疏忽,但我相當肯定這是類似的東西,因爲沒有別的意義。 – David 2013-02-14 19:47:37
