UWP:ContentDialog的大小和边距

我想要没有按钮/页边距的内容对话框

我在资源字典中使用了下一个代码（请注意所有0）：

0
0,0,0,0
0,0,0,0
0,0,0,0
0,0,0,0

如果我在XAML中设置内容对话框的宽度/高度，底部将被切断（如果没有，它将占据整个屏幕高度），如何修复它：

请注意，蓝色边距（对话框的背面是蓝色的），如何删除它

此外，对话框显示在顶部而不是中间

---

内容是一个具有0填充/边距的网格。

在模板中使用MaxWidth和MaxHeight来控制对话框的大小，您还可以在模板中使用

滚动查看器和固定
高度来创建一个固定高度的内容对话框，该对话框可以滚动其中的内容。
要删除页边距，还可以在此标记中更改模板：


这是我的对话框模板样式：

基本上，问题是在my Styles.xaml中，我的MinWidth对于ContentDialog样式（ContentDialogMinWidth）来说太大了

因此，系统将对话框内容水平居中（因为水平对齐是居中的），留下一个蓝色的空白空间（因为对话框背景不透明）

垂直对齐是顶部的，这就是为什么对话框出现在顶部。因为MaxHeight（ContentDialogMaxHeight）太小，所以它被切断了。增加它解决了这个问题

除此之外，我还需要删除固定对话框大小（从我的ContentDialog根目录中删除MinWidth、MaxWidth、MinHeight、MaxHeight）。
您希望实现什么效果？可能内容对话框不是合适的控件，请参阅主题。是否设置MaxHeight属性？我希望对话框与对话框内容之间没有边距。也可以设置固定的宽度和高度，但这会剪辑对话框的内容，如图所示。感谢@ParsaKarami，您让我想到将MinWidth/MaxWidth和MinHeight/MaxHeight设置为固定值。这将使对话框垂直居中。现在如何删除蓝色边距？谢谢，但问题在于固定的对话框大小，以及ContentDialog样式的MinWidth和MaxHeight。
