我的視窗（WPF）中有一個資料網格，其樣式如下（影像和 XAML 如下所示）
資料網格

問題是
- 由于某種原因，資料網格中似乎有一個額外的列沒有資料。我該如何擺脫它？我試過添加類似的東西
<Setter Property="Width" Value="*"/>` inside `<Setter Property="RowStyle"> <Setter.Value> <Style TargetType="{x:Type DataGridRow}">
但出現錯誤：
System.Windows.Markup.XamlParseException：'在'System.Windows.Baml2006.TypeConverterMarkupExtension'上提供值引發了例外。' 行號@@@@ 和行位置@@@。---> System.FormatException: '*' 字串不能轉換為長度。`
- 資料網格的最左側有一種白色邊框（見第一張圖片），我該如何擺脫它，并且滾動條設計也需要更改。有沒有人建議哪種型別的滾動條適合我的設計。如果你有類似的東西，請分享。
滾動條
我是新手，所以請幫忙。
uj5u.com熱心網友回復：
對于您的第一個和第二個問題，您可以直接在 Datagrid 樣式上使用以下屬性：
<Style TargetType="{x:Type DataGrid}" x:Key="test">
<Setter Property="ColumnWidth" Value="*"></Setter>
<Setter Property="HeadersVisibility" Value="Column"></Setter>
...
</Style>
- ColumnWidth設定為“*”允許您在所有列上使用相等的寬度。如果您在 Grid 上使用AutoGenerateColumns為 false，您還可以根據具體情況定義每列的寬度。
- HeadersVisibility設定為“Column”隱藏左側行選擇器。
關于滾動條的樣式，我給大家分享一個我使用的樣式：

由您來判斷它是否適合您的設計，但無論如何它會給您一個可以修改的基礎！
