WpfDatagridColumn宽度故障

Question

我有这个WpfDatagrid，我需要一个精确的宽度列，但我有一个问题。

我需要列“代码”有100的宽度。我需要列“描述”自动是占用最多它可以我需要列“活动”和“编辑”占用100的宽度

你传给我的代码和图片中的一样，我不能填满整个屏幕。谁能给我解释一下我做错了什么？imghttp://www.imagengratis.org/images/capturadh5jd.jpg[/img] http://www.imagengratis.org/images/capturadh5jd.jpg

Answer 1

我假设英语不是你的主要语言，但不清楚你想要什么。您可以将宽度分配给Converter并计算那里的宽度。

Answer 2

如果我没理解错的话，您希望列的宽度总是占用足够的空间来显示该列中的每一项，而不是拉伸和填充整个区域。

这是一个问题，因为默认情况下，数据网格是Virtualized的，所以直到滚动到不可见的项时才会加载它们。

您可以选择

• 将DataGridColumnWidth设置为等于*，以便占用所有剩余空间
• 禁用虚拟化(出于性能原因，不建议使用)
• 挂钩数据网格的已加载事件中的某些内容，该事件评估该列中每一项的内容，计算其呈现宽度，并将该列的宽度设置为等于最大值(由于初始加载时间，也不建议使用)
