WpfDatagridColumn的寬度故障

我有這個WpfDatagrid，我需要一個確切的寬度列，我有一個問題。WpfDatagridColumn的寬度故障

我需要列「代碼」有100寬度。我需要的列「說明」汽車是佔據最它能我需要的列「活動」和「編輯」佔據的寬度

100你通過我的代碼的方式仍然是相同的圖片，我無法填滿整個屏幕。有人可以解釋我，我做錯了嗎？ [IMG] http://www.imagengratis.org/images/capturadh5jd.jpg [/ IMG] http://www.imagengratis.org/images/capturadh5jd.jpg

需要查看DataGrid周圍的XAML。如何將DataGrid放置在窗口上。大小問題可能始於整個DataGrid的大小。 – Paparazzi

我使用完整代碼頁編輯答案 – Jorgechu

您是否嘗試設置Width =「*」而不是Width =「Auto」？ – hyp

我假設英語不是你的主要語言，但它不清楚你想要什麼。您可以將寬度分配給轉換器並計算寬度。

如果我理解你的權利，你希望你的列的寬度總是佔用足夠空間來顯示該列中的每個項目，但不能擴展和填充整個區域。

這是一個問題，因爲默認情況下DataGrid的是Virtualized，所以不可見的項目纔會加載，直到您滾動到它們。

您可以

設置你的DataGridColumnWidth等於*所以它佔用所有剩餘空間
禁用虛擬化（不推薦，由於性能原因）
胡克在DataGrid的加載事件東西評估該列中每個項目的內容，計算它們的渲染寬度，並將列的寬度設置爲最高數量（由於初始加載時間，也不是真正推薦的）
