WPF - Making a progressbar button and having it properly size

I am trying to make a button in WPF that will show progress but still have its button text visible.
I tried adding a Grid as a child to the button and adding a ProgressBar and Label to the grid, thinking the Grid will fill the button and using VerticalAlignment="Stretch" HorizontalAlignment="Stretch" on the progress bar and label will get me, basically, a clickable progress bar, that can show progress and have a label on top of it. However, I'm having problem with the sizing.
This is my XAML:
<Button Grid.Column="0" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" MinWidth="100" MinHeight="25" Margin="3">
<Grid>
<ProgressBar Value="10" Maximum="20" VerticalAlignment="Stretch" HorizontalAlignment="Stretch"/>
<Label Content="asd2" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" VerticalContentAlignment="Center" HorizontalContentAlignment="Center"/>
</Grid>
</Button>
This is what I see:
If I change to explicit sizing:
<Button Grid.Column="0" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" MinWidth="100" MinHeight="25" Margin="3">
<Grid>
<ProgressBar Value="10" Maximum="20" Width="100" Height="30" VerticalAlignment="Stretch" HorizontalAlignment="Stretch"/>
<Label Content="asd2" Width="100" Height="30" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" VerticalContentAlignment="Center" HorizontalContentAlignment="Center"/>
</Grid>
</Button>
I get this:
Which, visually, is an improvement, but XAML-programatically is worse, since I want the button to resize with the window, if the user can't see it well or something like that. Also, visually - I don't like that little border between the actual button and the start of the progressbar and I've tried setting both "padding" and "margin" to 0, it's not from that.
What I'd like to see - the progress bar taking up ALL the space of the button and the label text staying centered both vertically and horizontally, with respect to the total size of the button.

Put your <Grid> inside of a ControlTemplate and override your <Button.Template>:
<Button Grid.Column="0" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" MinWidth="100" MinHeight="25" Margin="3">
<Button.Template>
<ControlTemplate TargetType="Button">
<Grid>
<ProgressBar Value="10" Maximum="20" VerticalAlignment="Stretch" HorizontalAlignment="Stretch"/>
<Label Content="asd2" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" VerticalContentAlignment="Center" HorizontalContentAlignment="Center"/>
</Grid>
</ControlTemplate>
</Button.Template>
</Button>
What you were doing before is putting your <Grid> inside of the Button's ContentTemplate, not its Template. The problem with the ContentTemplate is that it has some of the default button's styling, such as the little border you don't like. By moving it to the Button's overall Template, you're saying I don't care about how the default button looks, I want it to look exactly like THIS.
What it can look like:
What it can look like if you resize the window:

Select anywhere inside Border

I'm trying to create a screen, or border where if the user click anywhere inside within this border. It should turn my border color RED. Currently i have my XAML setup as...
<StackPanel VerticalAlignment="Top" Orientation="Horizontal">
<Border Margin="10" Padding="10" BorderBrush="Blue" BorderThickness="1" MouseDown="OnMouseDown" Width="200" Height="200">
<TextBlock VerticalAlignment="Center" HorizontalAlignment="Center" TextWrapping="Wrap" Text="Click anywhere in here, the border should turn red" />
</Border>
<Border Margin="10" Padding="10" BorderBrush="Blue" BorderThickness="1" MouseDown="OnMouseDown" Width="200" Height="200">
<TextBlock VerticalAlignment="Center" HorizontalAlignment="Center" TextWrapping="Wrap" Text="Click anywhere in here, the border should turn red" />
</Border>
<Border Margin="10" Padding="10" BorderBrush="Blue" BorderThickness="1" MouseDown="OnMouseDown" Width="200" Height="200">
<TextBlock VerticalAlignment="Center" HorizontalAlignment="Center" TextWrapping="Wrap" Text="Click anywhere in here, the border should turn red" />
</Border>
</StackPanel>
And the output looks like this...
The problem now is that the "Border" is unable to recognize my MouseDown button. It doesnt register my mousedown anywhere inside the border, but only on the border itself. I want it so that if the user click anywhere inside, it should change my border color. How can i do that?
Please note that i need to eventually put content inside my border, be it a video, images, multiple UI controls, or whatever, so if user click anything inside this border, it should "select" my border and turn it red.
I experimented with other things like a Rectangle but Rectangle i cannot use because i am unable to put other UI elements or control in there.
Anyone know what is the correct way to do it?
Requirement:
within border selection, turn border red.
within border unselection, turn border back to blue.
border should eventually allow contents inside, such as the textblock, images, video, or anything.

Just add a transparent background to capture mouse clicks
<Border Background="Transparent" Margin="10" Padding="10" BorderBrush="Blue" BorderThickness="1" MouseDown="OnMouseDown" Width="200" Height="200">
<TextBlock VerticalAlignment="Center" HorizontalAlignment="Center" TextWrapping="Wrap" Text="Click anywhere in here, the border should turn red" />
</Border>
Note that any controls inside the border could steal events away from the border. In that case you may need a transparent border over the top of everything, or handle routed events. or just use a ToggleButton instead and change its template.

<StackPanel VerticalAlignment="Top" Orientation="Horizontal">
<StackPanel MouseDown="OnMouseDown">
<Border Margin="10" Padding="10" BorderBrush="Blue" BorderThickness="1" Width="200" Height="200">
<TextBlock VerticalAlignment="Center" HorizontalAlignment="Center" TextWrapping="Wrap" Text="Click anywhere in here, the border should turn red" />
</Border>
</StackPanel>
Wrap it inside container..

Unable to reorder items in GridView when WrapPanel is used UWP

And am creating a sorting app and in some cases i will hide the gridview item and i encountered the same error as this person:
Hide GridViewItem and reposition items in GridView
So I implemented the fix and it worked, but it suddenly disallowed be to drag and reorder items in my GridView.And from what I can tell it only appeared after I implemented the WrapPanel into my gridView.ItemsPanel and by removing it I am immediately able to reorder again.
and here's my XML code:

Image of when i try to drag and reorder GridView's Item with WrapPanel:
Am I missing something that is stated in the WinRTXamlToolkit, or there no way around this problem.
UPDATE 2017 Nov 27
So after some tinkering as suggested by # Xavier Xie - MSFT so try implement the drag and drop to reorder feature for winRT toolkit by inheriting the WrapPanel class and trying it from there.
Here's what I have found out so far,
winRT toolkit WrapPanel inherits Panel class
WrapPanel from other libraries like UWPCommunityToolkit
also inherits Panel hence making me thing that all Dynamic Wrapping needs to inherit the Panel class.
Panel class doesn't have any code for detecting item drag event (either that or I am dragging the wrong thing)
ItemsWrapPanel is a seal class making it impossible for me to inherit and that goes for any Interface it inherits as well
And this is concluded what I have found out so far and will continue to update this if I found anything.
Credits goes to # Xavier Xie - MSFT for pointing me into the right direction for this.

The WrapPanel of WinRTXamlToolkit has not implemented reordering function. You would need to implement the reordering manually, listening to the drag & drop events.
If you want to implement by yourself, you could read Jerry Nixon's blog Walkthrough: Reordering items in a GridView with Drag and Drop to understand the basic principle of GridView's reordering.
As a easy workaround, you could use ItemsStackPanel control as its ItemsPanel, it has implemented reordering function. This control also will not have space item there when you hide one item.

C# XAML Listbox collapse when clicked

I'm new in XAML for Windows Phone 8.1 and have some troubles with
making a Stackpanel clickable
collapse Item, when clicked
My work so far looks like that:
And the Code to that (please correct me, if there are major flaws):
<Border CornerRadius="15" Background="#FF595656" Margin="0" Grid.ColumnSpan="2" Height="80">
<StackPanel Orientation="Horizontal">
<StackPanel Width="20" HorizontalAlignment="Left" VerticalAlignment="Top" />
<StackPanel HorizontalAlignment="Left" Height="80" Margin="0,0,0,0" VerticalAlignment="Center" Width="51">
<Image HorizontalAlignment="Left" Height="51" Margin="0,15,0,0" Width="51" Source="Assets/fish.png" Stretch="Fill" RenderTransformOrigin="2.307,0.881" VerticalAlignment="Center"/>
</StackPanel>
<StackPanel Width="10" HorizontalAlignment="Left" VerticalAlignment="Top" />
<StackPanel HorizontalAlignment="Left" Height="80" Margin="0" VerticalAlignment="Top" Width="310">
<TextBlock HorizontalAlignment="Left" Height="25" Margin="0,20,0,0" TextWrapping="Wrap" Text="Entry 1" Width="310" VerticalAlignment="Top" FontSize="18" Foreground="Black" FontWeight="Bold"/>
<TextBlock HorizontalAlignment="Left" Height="17" Margin="0" TextWrapping="Wrap" Text="Short description Entry 1" Width="310" VerticalAlignment="Top" Foreground="#FF0097FF"/>
</StackPanel>
</StackPanel>
</Border>
This code will later be wrapped inside a ListBox with Image, Entry 1 and the short description being bound:
<ListBox x:Name="ListBox1" Margin="0"
Width="400" Height="200" HorizontalAlignment="Left"
ItemsSource="{Binding}" Grid.Row="1" VerticalAlignment="Top" Grid.ColumnSpan="2" >
<ListBox.ItemTemplate>
<DataTemplate>
// the code above
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
So my question is:
How can I make a nice looking expansion/collapse of each Item in the ListBox, whenever I click on it?
Thank you very much in advance.

The real question is here is what do you want it to collapse to? There are too many possible ways to collapse some visual data item. Do you just want to change the height of the item or do you want some fancy animation that collapse some property?
If the height is what you're looking for it's pretty easy. Just attach an Tap Event on that Border of yours. On a sidenote, you probably want to edit the ItemContainerStyle to have <Setter Property="HorizontalContentAlignment" Value="Stretch"/> so the Listbox will stretch across the screen, otherwise imho it's un-useable.
<ListBox.ItemTemplate>
<DataTemplate>
<Border BorderBrush="Red" BorderThickness="0,1" Tap="Border_Tap">
<StackPanel>
<!--- rest of template --->
</StackPanel>
</Border>
</DataTemplate>
</ListBox.ItemTemplate>
Then calculate the Minimum height you want to show (make sure it's actually useable, meaning... I can Tap on it again to show the whole thing without using a Mag Glass).
private void Border_Tap(object sender, System.Windows.Input.GestureEventArgs e)
{
int minHeight = 40; // change to whatever you want
Border b = sender as Border;
if (b.ActualHeight > minHeight)
{
b.Height = minHeight;
}
else
{
b.Height = double.NaN; // this will change the height back to Auto, showing everything
}
}
Code In Action
This is just a quick solution to your question. Some people on here would rather have you create a StoryBoard Animation on the Height Property of the Selected state in the VisualStateManager. If you reword or create a new question explicitly stating you want a VisualStateManager solution, I will provide you one as well. Good luck.

Change XAML Margin in universal app based on resolution

I am working on a Universal app for Wp8.1/WinRt.
For the phone, I have a gridview that displays grids containing stackpanels as 'ItemTemplate'.
The grids have margins specified explicitly, like so:
<GridView ItemsSource="{Binding CurrentItems}">
<GridView.ItemTemplate>
<DataTemplate>
<Grid Width="140" Margin="6,0,6,6" x:Name="I_WANT_TO_ADJUST_MY_MARGINS">
<Border Background="{StaticResource PhoneAccentBrush}"/>
<Grid Height="140" Width="140">
<Image VerticalAlignment="Top" Margin="10" Width="100" Height="100" Source="{Binding Converter={StaticResource ImageConverter}}" HorizontalAlignment="Center" />
</Grid>
<Grid VerticalAlignment="Bottom">
<Border Background="{StaticResource PhoneBackgroundBrush}" Opacity="0.6"/>
<TextBlock Text="{Binding DisplayedName}" Style="{StaticResource BodyTextBlockStyle}" Margin="3" TextWrapping="Wrap"/>
</Grid>
</Grid>
</DataTemplate>
</GridView.ItemTemplate>
</GridView>
This looks great on a 6" inch phone giving me a 3 column look. But on a small phone, while I get two columns, the amount of negative space on the right is horrible.
I want to be able to make the margins of the grid I_WANT_TO_ADJUST_MY_MARGINS bigger if the screen is smaller?
Note: This layout is specifically for running on the phone.

This is how I solved it:
Add two datatemplates (big/small screen) to a resources dictionary - I used the page resources, but you can probably use any.
Add a DataTemplateSelector to the page resources. Specify the above two templates as properties, like so:
<local:WpDataTemplateSelector x:Key="WpDataTemplateSelector" BigScreenTemplate="{StaticResource BigScreen}" SmallScreenTemplate="{StaticResource SmallScreen}"></converters:WpDataTemplateSelector>
In the DataTemplateSelector use the following to determine screen width:Window.Current.Bounds.Width
Specify the ItemTemplateSelector property on the GridView
