My problem is: I have two sizes of window which changes according to CheckBox. Below have a screenshot of the problem:

Like you can see, my app starts with incorrect size but when I change the checkbox everything works fine, the window size become normal

I already tested to set CheckBox when app starts by code behind and not work.

Here's my XAML of custom windowstyle

    <Style x:Key="CustomWindowStyle" TargetType="{x:Type Window}">

        <Setter Property="shell:WindowChrome.WindowChrome">

            <Setter.Value>

                <shell:WindowChrome 

                    GlassFrameThickness="-1"

                    ResizeBorderThickness="5"

                    CaptionHeight="36"/>

            </Setter.Value>

        </Setter>

        <Setter Property="BorderBrush" Value="#FF2D2D30" />

        <Setter Property="Background" Value="#FF2D2D30" />

        <Setter Property="SnapsToDevicePixels" Value="true" />

        <Setter Property="BorderThickness" Value="15,35,15,15"/>

        <Setter Property="Template">

            <Setter.Value>

                <ControlTemplate TargetType="{x:Type Window}">

                    <Grid>

                        <Border

ADDEND:

If I remove the custom window style, works fine, so it's something i'm missing there.

You can get rid of this behaviour by removing SizeToContent="WidthAndHeight" from your XAML and setting the SizeToContent programmatically once the window has been loaded:

public partial class Window_SelectConnection : Window

{

    public Window_SelectConnection()

    {

        InitializeComponent();

        Loaded += OnLoaded;

    }



    private void OnLoaded(object sender, RoutedEventArgs e)

    {

        SizeToContent = SizeToContent.WidthAndHeight;

        Loaded -= OnLoaded;

    }

}

You may want to create a custom window class that does this for you:

public class CustomWindow : Window

{

    public CustomWindow()

    {

        Loaded += CustomWindow_Loaded;

    }



    private void CustomWindow_Loaded(object sender, RoutedEventArgs e)

    {

        SizeToContent = SizeToContent.WidthAndHeight;

        Loaded -= CustomWindow_Loaded;

    }

}

...and inherit from this one:

public partial class Window_SelectConnection : CustomWindow



<local:CustomWindow x:Class="STEP_QuickSound_UI.Window_SelectConnection" ...
