How to set fixed window size for Universal Windows Application

问题

I just started to develop an Universal Windows Application in VS2015 Community Edition. I have used the sample called PieCharts for Windows UWP.

My problem is that I whould like to fix the window size to 400x650 as I did in my old desktop applications. I have set Width and Height manually It does not work. My MainPage.xaml is something like the following code.

<Page x:Class="MyFistUWP.MainPage"
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
  xmlns:local="using:MyFistUWP"
  xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
  xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
  MaxHeight="650" MinHeight="650" MaxWidth="400" MinWidth="400" Height="650" Width="400" >

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="140" />
        <RowDefinition Height="*" />
    </Grid.RowDefinitions>

    <Image Grid.Row="0" Source="Resources/my_logo.png" />
</Grid>

The window size is wrong and I can resize window.

Thanks,

You can use this code for set minimal size of application: ApplicationView.GetForCurrentView().SetPreferredMinSize(new Size(400, 650));

I found a solution. I think its not the best, but it works.
XAML:

     <Grid Background="#4A9130" SizeChanged="FormName_SizeChanged">

    private void FormName_SizeChanged(object sender, SizeChangedEventArgs e)
    {

        ApplicationView.GetForCurrentView().TryResizeView(new Size(900, 600));
    }

Hope it helps

I guess the only choice is use OnSizeChanged Method to control size of window. It's work's for me. Maybe not the best choice but really easy way to solve problem.

private void FormName_SizeChanged(object sender, SizeChangedEventArgs e)
{
    if((this.Width != 400) & (this.Height != 650))
    {
        this.Width = 450;
        this.Height = 650;
    }
}
