因此,我在视图框内有一个网格。现在,网格与视图框精确匹配。但是,我需要知道ViewModel中网格的高度和宽度。然而,它似乎并没有将高度设置为任何东西?尝试将网格的高度/宽度绑定到ViewModel
<Viewbox VerticalAlignment="Top" Margin="5,20,5,0">
<Border BorderThickness="6" BorderBrush="Black" CornerRadius="2">
<Grid MinHeight="300" MinWidth="400" Height="{Binding Height, Mode=TwoWay}" Width="{Binding Width, Mode=TwoWay}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Grid.Column="0" >
<ItemsControl ItemsSource="{Binding Viewers}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<Canvas />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemContainerStyle>
<Style>
<Setter Property="Canvas.Left" Value="{Binding X}" />
<Setter Property="Canvas.Top" Value="{Binding Y}"/>
</Style>
</ItemsControl.ItemContainerStyle>
</ItemsControl>
</Grid>
</Border>
</Viewbox>
而且在我的ViewModel:
private int _height;
public int Height
{
get
{
return _height;
}
set
{
_height = value;
OnPropertyChanged("Height");
}
}
private int _width;
public int Width
{
get
{
return _width;
}
set
{
_width = value;
OnPropertyChanged("Width");
}
}
任何想法?
你有正确的'DataContext'? – 2012-04-21 21:58:27
对于相同View/ViewModel的任何其他DataBindings都没有问题,所以我假设如此。 – benjgorman 2012-04-21 21:59:26
我希望在改变数值时不要保持长宽比,因为那只会在边框的角半径中可见。 – 2012-04-21 22:01:05
