使其更清晰的未來的讀者,這裏的問題及其修復的摘要。
我的網格坐落在一個頁面中,用作tabitem的內容。在運行時,網格拒絕填充整個tabitem區域,如下面的屏幕截圖所示。
問題是,tabitem的樣式包含一個內容模板,通過contentpresenter顯示頁面,在裏面有一個水平的堆疊面板。堆疊面板覆蓋頁面中網格的拉伸屬性。
解決方案是用網格替換樣式中的堆棧面板。沒有更多的佈局問題。
原來的問題
我有一個StackPanel與網格內的標籤和文本框,我想文本框的寬度綁定到網格中的前兩列的寬度。我一直在使用綁定文本框寬度到其父母的方法,並試圖綁定值到東西具有正確的值,但我也嘗試過直接綁定以及沒有運氣。
這是我的XAML:

我從各種問題和其他網站嘗試了幾種建議的變通辦法,但沒有什麼工作。我嘗試在我想綁定到的單元格上粘貼一個邊框並綁定到它的尺寸,使用標籤嵌套另一個網格,x:命名ColumnDefinition並綁定到ActualWidth等。沒有。作品。
這似乎是wpf中應該非常簡單的事情,而我只是錯過了至關重要的小作品。我浪費了大概三個小時。我究竟做錯了什麼?
編輯:
我才意識到,這似乎是我綁定到整個GridMainContent的寬度 - 我不是。這只是一種虛擬價值,已經被我嘗試過的每種不同解決方案所取代。
這是我的問題的圖像。內容應該填滿整個標籤。請注意,周圍的網格大小調整爲以調整內容,而不是調整的內容以適合網格的。我已經爲我的內容定義了每個父元素的HorizontalAlignment = Stretch的隱式樣式,但似乎沒有任何工作。
我期望它做的是左邊部分(帶下拉框)和右邊部分(銷售代表&等)的寬度相等,填充選項卡的整個內容區域。
試着避免綁定,使用WPF佈局。 – user3455395
這是不可接受的。我需要寬度與其父寬度正確縮放。 – Travis
給你的網格兒童Grid.ColumnSpan = 4有什麼問題? – user3455395
