首先,这是我使用Xaml的第一天所以这个问题对你来说可能是假的,但我完全迷路了.
概观
我的技术是我有MainWindow.xaml,它被分成三个区域(使用网格列)自动设置列宽.
基于右列中的某些操作,显示页面的中间列让我们说不同命名空间中存在的Page.xaml.
我正在寻找什么
问题是我需要将此页面的宽度和高度设置为等于中间列宽度和高度,因为它将适合此区域.
笔记
我对xaml和绑定技术的经验很少.
MainWindow.Xaml
<Window

WindowState="Maximized"
ResizeMode="NoResize"
WindowStartupLocation="CenterScreen"
Title="MainWindow" d:DesignWidth="1366" d:DesignHeight="768">
<Grid x:Name="MainGrid">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1.2*" x:Name="LeftColoumn" />
<ColumnDefinition Width="3*" x:Name="CenterColoumn" />
<ColumnDefinition Width=".8*" x:Name="RightColoumn" />
</Grid.ColumnDefinitions>
<ScrollViewer Grid.Column="2">

Other Xaml file
<Page
x:Name="Page"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

mc:Ignorable="d"
Title="Any" d:DesignWidth="1364" d:DesignHeight="868"
>
<Grid>
<Frame Background="DarkGray" />
</Grid></Page>
MainWindow.xaml.cs
private void Button_Click(object sender, RoutedEventArgs e)
{
Frame middleFrame=CenterColumn;
Otherxaml other=new Otherxaml();
middleFrame.Source = new Uri("OtherxamlPage.xaml", UriKind.RelativeOrAbsolute);
}
最佳答案 与您的代码段相关,您可以将OtherxamlPage.xaml放在中心框架内并设置该框架的属性,如下所示:
<Frame Grid.Column="1" x:Name="CenterFrame" VerticalAlignment="Stretch" VerticalContentAlignment="Center" HorizontalAlignment="Stretch" HorizontalContentAlignment="Center" Source="OtherxamlPage.xaml" Background="DarkGray" />
您可以在事件处理程序中动态设置Source =“OtherxamlPage.xaml”,例如Button.Click根据您的示例.
或者,考虑创建WPF UserControl(re:https://msdn.microsoft.com/en-us/library/cc294992.aspx)而不是其他XAML窗口(或页面),并将其直接放入网格单元格中.在这两种情况下都设置内容“Stretch”属性以便自动调整其大小,因此您无需在代码中指定它.
希望这可能有所帮助.
