UWP: Content dialog width stays the same - xaml

Question

I have tried to set the width and also min height and min width but still the dialogue wont change to full screen. tried window.bounds too but teh dialog wont expand beyond a fixed width.
public sealed partial class ContentDialog1 : ContentDialog
{
public ContentDialog1()
{
this.InitializeComponent();
this.MinWidth = Window.Current.Bounds.Width;
}
private void ContentDialog_PrimaryButtonClick(ContentDialog sender, ContentDialogButtonClickEventArgs args)
{
}
private void ContentDialog_SecondaryButtonClick(ContentDialog sender, ContentDialogButtonClickEventArgs args)
{
}
}
}
<ContentDialog
x:Class="PowerUp.UWP.View.ContentDialog1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:PowerUp.UWP.View"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
Title="TITLE"
PrimaryButtonText="Button1"
SecondaryButtonText="Button2"
PrimaryButtonClick="ContentDialog_PrimaryButtonClick"
SecondaryButtonClick="ContentDialog_SecondaryButtonClick"
MinWidth ="2000">
<Grid x:Name="cd1" >
</Grid>
This is what I want
This is how content dialog is shown in my application

Answer 1

It is actually very simple, did a bit research and found the simplest answer, you can keep doing what you were already doing in the first place and just set the FullSizeDesired property of your ContentDialog to true.
Popup
Or you can try it with popup.
var c = Window.Current.Bounds;
var okButton=new Button{Content="Ok"};
okButton.Click += okButtonClicked; // now where you have this okButtonClicked event you can execute any code you want including, closing the popup.
var g = new Grid
{
Width = c.Width,
Height = c.Height,
Background = new SolidColorBrush(Color.FromArgb(0x20, 0, 0, 0)),
Children =
{
new StackPanel
{
Width = 400,
Height = 200,
Background = new SolidColorBrush(Colors.White),
Children=
{
new TextBlock{Text="Title"},
new TextBlocl{Text="description"},
okButton
}
}
}
};
var p = new Popup
{
HorizontalOffset = 0,
VerticalOffset = 0,
Width = c.Width,
Height = c.Height,
Child = g
};
p.IsOpen = true; // open when ready
Notice that Child of popup is g which is a grid, you can put your content within this grid or you can use a StackPanel instead of this grid and then put your contents within that StackPanel, whatever you want to do here is your decision, putting elements in popup is exactly like putting elements in a ContentDialog.
Achieving the same with a simple Grid alongside your frame
<Grid>
<Grid Horizontallignment="Stretch" VerticalAlignment="Stretch" Visibility="Collapsed" x:Name="ContentGrid" canvas.ZIndex="5"><--this grid will act as content dialog, just toggle its visibility to the backend-->
<--put all your content here along with your ok and cancel buttons-->
</Grid>
<Frame/> <--this is the code where you have your frame-->
</Grid>
in above code the frame and your actually content grid will be parallel to each other, and whenever content grid is visible only it will be shown in the app because it has ZIndex greater than 0 and your frame will hide behind it, and whenever its visibility is collapsed it will not be shown and you will be able to see your frame normally.
