WPF DataGrid：在不扭曲ControlTemplate的情况下，从数据网格中删除内部滚动查看器
WPF DataGrid：在不扭曲ControlTemplate的情况下，从数据网格中删除内部滚动查看器
提问于 2018-06-25 02:15:35
请了解如何从WPF中的DataGrid控件模板中删除内部滚动查看器。下面是包含ScrollViewer的ControlTemplate。对于如何在不破坏数据集功能的情况下从模板中删除滚动查看器和滚动条，有什么想法吗？
我有一个自定义滚动条，我已经设计在我的应用程序中使用，所以内部滚动查看器在数据不允许我做顺利滚动。留给我两个选择。要么我从下面发布的DataagridControl模板中删除内部滚动查看器，要么删除我的自定义滚动条。我想保留我的自定义滚动条，所以我需要帮助移除控件模板中的滚动条。我尝试用StackPanel替换ScrollviewerControl，然后完全删除滚动条，但是我收到了一条错误消息，上面写着
成员“模板”无法识别或无法访问。
如有任何帮助，我们将不胜感激。
下面是我要修改的Control模板

<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}" SnapsToDevicePixels="True">

为什么不禁用DataGrid自己的ScrollViewer而不是从模板中删除它呢？
2附加属性：
<DataGrid ScrollViewer.HorizontalScrollBarVisibility="Disabled"
ScrollViewer.VerticalScrollBarVisibility="Disabled" />页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
