How to resize content when maximize window in WPF?-CodePudding

I have this window and I would like to resize content ( fit it to the size of window ) when the user maximize this window , I've tried many solutions but any of them worked for me :

<Window x:Class="Window_Image"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
         xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
         mc:Ignorable="d" 
         d:DesignHeight="550" d:DesignWidth="550">
<Grid>
    <DockPanel LastChildFill="True" Name="ImgDock"  Background="Transparent" >
        <Image Source="../res/myimage.png" Width="450" Height="450" x:Name="ImageComp"  Visibility="Visible" > 
      </Image>
    </DockPanel>
</Grid>

Unfortunatly , this solution didn't works for me.

CodePudding user response：

The issue was that the Image size was hardcoded (Height and Width properties).

By default, most of WPF's component will adjust their size to fill their containers.
