Question

I have the following Window created in WPF. This is how it’s shown:

I have no idea why the screen is shown so big and I don’t know how to debug why is it getting so wide.

This is the code related to the problem:

<Window x:Class="Picis.CpCustomize.CustomizeControls.Dialogs.EditIntegerWindow"
MinWidth="350"
SizeToContent="Height"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
ResizeMode="CanResize" 
ShowInTaskbar="False" 
WindowStartupLocation="CenterScreen" 
WindowState="Normal"
Loaded="OnWindowLoaded">

<!-- Main frame -->
<Grid>

    <!-- Layout -->
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto"/>
        <ColumnDefinition Width="*"/>
    </Grid.ColumnDefinitions>

    <TextBlock VerticalAlignment="Center" MinWidth="100" TextAlignment="Right">
        <TextBlock.Text>
            <Binding Converter="{StaticResource Localizer}" ConverterParameter="General.Value" />
        </TextBlock.Text>
    </TextBlock>

    <TextBox x:Name="valueTextBox" Grid.Column="1" Margin="5" Text="{Binding Path=Value}"/>

    <TextBlock  VerticalAlignment="Center"  Grid.Row="1" Grid.Column="0"  HorizontalAlignment="Right" Visibility="{Binding Path=ShowComments, Converter={StaticResource VisiConv}, ConverterParameter=Collapse}" MinWidth="100" TextAlignment="Right">
            <TextBlock.Text>
                <Binding Converter="{StaticResource Localizer}" ConverterParameter="EditParamDlg.Comment" />
            </TextBlock.Text>
    </TextBlock>

    <TextBox x:Name="commentTextBox" Grid.Row="1" Grid.Column="1" Margin="5" Visibility="{Binding Path=ShowComments, Converter={StaticResource VisiConv}, ConverterParameter=Collapse}" Text="{Binding Path=Comment}"/>

    <CheckBox Grid.Row="2" Grid.Column="1" Margin="5" x:Name="isDeletedCheckBox" Visibility="{Binding Path=ShowIsDeleted, Converter={StaticResource VisiConv}, ConverterParameter=Collapse}"
            IsChecked="{Binding Path=IsDeleted}">
        <CheckBox.Content>
            <Binding Converter="{StaticResource Localizer}" ConverterParameter="EditParamDlg.IsDeleted" />
        </CheckBox.Content>
    </CheckBox>

    <UniformGrid Grid.Row="3" Grid.Column="1" Margin="5" HorizontalAlignment="Right" Columns="2">
        <Button  x:Name="okButton" Click="OnOk"  IsDefault="True">
            <Button.Content>
                <Binding Converter="{StaticResource Localizer}" ConverterParameter="General.Ok" />
            </Button.Content>
        </Button>
        <Button x:Name="cancelButton"  Click="OnCancel" Margin="5,0,0,0"  IsCancel="True">
            <Button.Content>
                <Binding Converter="{StaticResource Localizer}" ConverterParameter="General.Cancel" />
            </Button.Content>
        </Button>
    </UniformGrid>

</Grid>
</Window>

My first question is how to debug this issue, the second one is what is happening in this specific scenario.

Thanks in advance.

This question is a duplicate of: Why are my WPF window sizes defaulting to be huge

And according to: Window Size when SizeToContent is not specified the default size when not specified is 60% of the width and 60% of the height of your primary screen.
