防止在WPF C＃中调整控件的大小

Question

(Edit) i have an image in tabItem1. when i resize window(dragging by corner or maximize button) the image also resize and occupy whole grid. i added width and height on image and the resisng stopped default to actual image width & height in pixels.

Do i have to apply width and height to prevent resising of control whom i don't want to resize on window scale? or is there any property for controls to prevent resizing.

Basically, i'll have some pics which i don't want to be resided, and there will be some text which i want to be resided.

XAML:

<Window x:Class="Engine.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Width="600" Height="600">
    <Grid>
        <TabControl Grid.RowSpan="2">
            <TabItem Header="TabItem1">
                <ScrollViewer HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto">
                    <Grid x:Name="TGrid1" Background="#FFE5E5E5"/>
                </ScrollViewer>
            </TabItem>
            <TabItem Header="TabItem2">
                <ScrollViewer HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto">
                    <Grid x:Name="TGrid2" Background="#FFE5E5E5">
                        <Grid.RowDefinitions>
                            <RowDefinition/>
                            <RowDefinition/>
                        </Grid.RowDefinitions>
                    </Grid>
                </ScrollViewer>
            </TabItem>
        </TabControl>
    </Grid>
</Window>

Code:

public MainWindow()
{
        InitializeComponent();

        var bitmapFrame = BitmapFrame.Create(new Uri(@"" + AppDomain.CurrentDomain.BaseDirectory + "Chrysanthemum.jpg"), BitmapCreateOptions.DelayCreation, BitmapCacheOption.None);
        var dragDropImage = new Image
        {
            Source = bitmapFrame, //new BitmapImage(new Uri(@"" + AppDomain.CurrentDomain.BaseDirectory + "Chrysanthemum.jpg")),
            Name = "dragDropImage",
            Width = bitmapFrame.PixelWidth,
            Height = bitmapFrame.PixelHeight
        };
        TGrid1.Children.Add(dragDropImage);

        var rect = new Rectangle
        {
            Stroke = new SolidColorBrush(Colors.Red),
            Fill = new SolidColorBrush(Colors.Black),
            Width = 474,
            Height = 405
        };
        Grid.SetRow(rect, 0);
        TGrid2.Children.Add(rect);
  }

Answer 1

If you set the properties VerticalAlignment (for example to Top ) and HorizontalAlignment (for example to Left ) of your components image and rect , these controls will be sized according to the content need, instead of the available space in the container.

Is that what you want ?

EDIT : For your image, you should set its property Stretch="None" . See here .

EDIT 2 :

var dragDropImage = new Image
        {
            Source = bitmapFrame, //new BitmapImage(new Uri(@"" + AppDomain.CurrentDomain.BaseDirectory + "Chrysanthemum.jpg")),
            Name = "dragDropImage",
            VerticalAlignment = System.Windows.VerticalAlignment.Top,
            HorizontalAlignment = System.Windows.HorizontalAlignment.Right,
            Stretch = System.Windows.Media.Stretch.None
        };
