While using the Appbar button in the CommandBar of a Page, content of the Appbar button is fixed it seems. So that the width is not increase based on the Content.
Is there any work around to make visible the whole content or like wrapped content?
Thanks in advance.
<CommandBar BorderBrush="White"
BorderThickness="1"
IsSticky="True">
<CommandBar.PrimaryCommands>
<AppBarButton Icon="Accept" Label="return to yard" />
</CommandBar.PrimaryCommands>
</CommandBar>
It's funny but it depends on your phone's language. I have discovered it in my own app, where one of AppBar buttons has long label. When the language is set to Polish, then the label wraps and has two lines. But in English it has the same problem like you... One line and clipped (first button in screenshots below).
Polish:
English:
The answer to your question is: there is no way to change the size of AppBar buttons or labels. You have to come up with some shorter label...

I am writing a UWP 14393 app using mediaplayerelement in xaml file, I am wondering how can I display extra information in text on top of custom transport media control so that when player control is up, the text will show up at the same time?
For example, for a video player showing an online stream, and at the top left corner shows streamer name, view count, etc. The information only shows up when player control shows up.
Obviously, the best way to do this is to put the text inside custom transport media control, is it doable? If not, how can I achieve this?
I am a newbie at UWP, so any help will be welcome, thanks.
You can custom the MediaTransportControls's style, and add your own content to <Border x:Name="ControlPanel_ControlPanelVisibilityStates_Border">. See my test.
First download MediaTransportControls's style from my gist.
Or you can find it in your pc's generic.xaml file.
Then add this style to App.xaml.
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/MediaTransportControls.xaml"/>
</ResourceDictionary.MergedDictionaries>
Then you can use your style in MediaTransportControls.
<MediaPlayerElement
Width="300" Height="500"
AreTransportControlsEnabled="True"
Source="ms-appx:///Assets/elephantsdream-clip-h264_sd-aac_eng-aac_spa-aac_eng_commentary-srt_eng-srt_por-srt_swe.mkv">
<MediaPlayerElement.TransportControls>
<MediaTransportControls Style="{StaticResource myMediaTransportControlsStyle}">
</MediaTransportControls>
</MediaPlayerElement.TransportControls>
</MediaPlayerElement>
<MediaPlayerElement AreTransportControlsEnabled="True">
<MediaPlayerElement.TransportControls>
<MediaTransportControls>
<Grid>
<...Put any content here like textblocks and buttons all this content will be part of controls so they will appear and disappear along with the controls, this Grid covers all the area on the screen ( above the controls bar )...>
</Grid>
</MediaTransportControls>
</MediaPlayerElement.TransportControls>
</MediaPlayerElement>
I have layout as described below:
<ScrollViewer>
<StackPanel Orientation="Horizontal">
<!-- ... -->
<ScrollViewer>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel ScrollViewer.VerticalScrollBarVisibility="Visible" Orientation="Vertical" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ScrollViewer>
<!-- ... -->
</StackPanel>
</ScrollViewer>
And I would like to achieve that effect that is present in weather app.
In my application, when you're scrolling horizontaly using mouse wheel, when pointer gets over ItemsControl it immediately starts scrolling verticaly wheras in weather application there's fluent horizontal scrolling effect and scrolling verticaly begins when there's some time hover that vertical collection.
Is that behaviour somewhere implemented by default?.

Generally, the guideline is that introducing vertical scrolling in a horizontally scrolling repeater is a bad idea. I think you should NOT consider Weather (or any standard Windows 8 app) as a model to emulate. Most of them violate the guidelines in some of the worst ways.
The Weather app accomplishes what you are asking based on the current mouse placement, the motion of the grid, and control with focus. That's a complex way of saying, some developer dreamed up a solution to help make their UI as confusing to the user as possible.
Please, don't.
What I think they do in order to achieve that effect is this:
If the mouse is over the vertical list for a while, they deactivate the horizontal scroll and activate the vertical one. Once the mouse moved outside the list, they switch back (deactivate the vertical scroll and activate the horizontal scroll).
I have not tested this to see if this works, but I think it should.
So I have come to that point where I am saying to myself over and over again I am missing some basic stuff.
I have a ScrollViewer with a RichTextBlock that converts HTML to the content.
Everything shows up as expected but I can't scroll! I had the VerticalScrollBarVisibility to Hidden but I have taken that out. After seeing this anwsear in StackOverflow I have stoped with the following code:
<ScrollViewer VerticalAlignment="Stretch"
HorizontalScrollMode="Disabled"
VerticalScrollBarVisibility="Visible"
VerticalScrollMode="Auto"
ZoomMode="Disabled"
Padding="52"
Background="#60000000" >
<RichTextBlock rtbx:Properties.Html="{Binding TextHTML}"
TextAlignment="Justify"
FontSize="20" />
</ScrollViewer>
It also seems that the PanningMode is not avaiable in Windows 8 but I belive that it is still the expected behaviour to scroll with the touch.
I have tried to put the ManipulationMode to All in the ScrollViewer and also tried to set to none in the RichTextBlock. However, I got no sucess with those approaches.
Removing the manipulation modes and isolating the problem and simplifing the "options" I was using led me to the conclusion that the ScrollViewer wasn't the issue.
The problem was: I had was a Control that was on top of the ScrollViewer that was hidden (opacity = 0). This Control swallowed all the events that I was needing in the ScrollViewer. Basic mistake.
I had to put the Visibility equals to Collapsed.
So I have a grid with a background. Inside the grid is a WebView and then some space on the left hand side of the screen where I have just placed a Button for now.
As the program runs, the left hand bar (that shows the grid with the background and the button laid out on it) doesn't render, instead I get the background, no controls on it and a black triangle (or geometric shape) at the bottom.
I suspect it's an issue with the VM and the video driver. I had a similiar issue with WPF a few years ago and MS's response was that I had an incompatible video driver that was causing the form to not render correctly at all times (this is very much the same behavior).
What can I do to prevent this? I'm including an image.
I'm going to include the small XAML I used and then a screenshot of the behavior (The XAML I rekeyed by hand):
<Grid>
<Grid.Background>
<ImageBrush ImageSource="Media/Background.jpg" />
</Grid.Background>
<TextBlock FontSize="24" Margin="15,15,0,0">Sample Label</TextBlock>
<WebView x:Name="wv1" Margin="250,0,0,0"></WebView>
<Button Content="Do Something" HorizontalAlignment="Left" Height="42" Margin="57,131,0,0" VerticalAlignment="Top" Width="170" Click="Button_Click1" />
</Grid>
VMs don't work well with multimedia. You should expect all sorts of problems with video.
I have the following snippet:
<StackPanel>
<Popup>
<TextBox ToolTip="Edit current date"/>
</Popup>
<Label "Current Date"/>
</StackPanel>
I want the popup to show when the StackPanel is clicked, and hidden when it (the Popup) loses focus.
I was wondering what would be the shortest way to write this in xaml.
To do this with an animation, use BooleanAnimationUsingKeyFrames. The example shows how to animate the IsEnabled property but will work equally well with Popup.IsOpen. (You'll need to scroll waaaay down to see the XAML example.) Take care about the FillBehavior so that the Popup doesn't animate back to being closed when the animation ends (unless of course this is what you want!).
