WPF ResizeMode Changes Window Size

Question

I am currently making a wpf application and want to disable window resizing during certain operations. I have been using this.ResizeMode = System.Windows.ResizeMode.CanMinimize;, which does exactly what I want, but it makes the window larger than before.

I don't know if it's possible, but is there a way to avoid the enlarging of the window?

EDIT:

Here's a very simple wpf application that demonstrates this problem.

xaml:

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Button Content="Trigger CanMinimize" Height="23" HorizontalAlignment="Left" Margin="62,248,0,0" Name="canMin" VerticalAlignment="Top" Width="120" Click="canMin_Click" />
        <Button Content="Trigger CanResize" Height="23" HorizontalAlignment="Left" Margin="327,248,0,0" Name="canRes" VerticalAlignment="Top" Width="108" Click="canRes_Click" />
    </Grid>
</Window>

cs file:

using System.Windows;

namespace WpfApplication1
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void canMin_Click(object sender, RoutedEventArgs e)
        {
            this.ResizeMode = System.Windows.ResizeMode.CanMinimize;
        }

        private void canRes_Click(object sender, RoutedEventArgs e)
        {
            this.ResizeMode = System.Windows.ResizeMode.CanResize;
        }
    }
}

Answer 1

Actualy I don't really understand what "makes window larger" means, but alternatively you can set

MaxWidth = ActualWidth;
MinWidth = ActualWidth;
MaxHeight = ActualHeight;
MinHeight = ActualHeight;

instead of

this.ResizeMode = System.Windows.ResizeMode.CanResize;

In case you want to re-enable resize set those properties to double.NaN.

To disallow resizing simply do the following:

ResizeMode = ResizeMode.NoResize;

It will also remove the minimize and maximize buttons.
