I am trying to add an image to a button . I want to archive something like this
This is what I was trying to do but the image doesn't appear
<StackPanel Orientation = "Horizontal">
<Button x:Name = "kap2"
FontFamily = "Arial"
Content = "Te drejtat dhe lirite themelore"
Width = "250"
Height = "50"
HorizontalAllignment = "Left">
<Button.Background>
<ImageBrush ImageSource = "Asses/number/1.png" Stretch="Fill">
</ImageBrush>
</Button.Background>
</Button>
</StackPanel>
The word 'Asses' I think it should be 'Assets'.
If this doesn't work, try also
/Assets/number/1.png
The problem is about spelling. Make sure that folder names are correct and the image name is correct too.

Background
I'm trying to put a textBlock control at the bottom of the screen (with a small margin below it), and I also wish to set a background for it, so that no matter what is shown behind the textBlock, it will be easy to read.
On Android, you could simply set the background to it, and tell it to have the width and height to be WRAP_CONTENT, so that it will take only the space it needs, but I can't find a similar thing on WP8.
Current status
This is the xaml I've created:
...
<Grid >
<Image x:Name="fullScreenImage" Stretch="Fill"
Visibility="Collapsed" />
<TextBlock HorizontalAlignment="Center" VerticalAlignment="Bottom"
Margin="0,0,0,200" FontSize="40" x:Name="pictureLabel" TextWrapping="Wrap"
Foreground="#ff000000" />
</Grid>
The problem
Since the textBlock doesn't have a background property, I had to use something that wraps it. However, since its content changes dynamically, I can't simply set a size for it.
The question
For now, I would like to simply set its background color.
I would also very appreciate if it would be possible to use a rounded corners rectangle for the background, or a 9-patch image.
How can I achieve setting a background for the textBlock?
The solution is very simple. Just set the HirizontalAlignment to Left. Hope this will work in your case.
<StackPanel HorizontalAlignment="Left">
<Border Background="#66FFFFFF">
<TextBlock/>
</Border>
</StackPanel>
According to this question (which is for Silverlight - but is xaml nonetheless), there is no way to explicitly set a background color for a TextBlock. Your best bet is to wrap your TextBlock in a Grid or Border.
If a Grid does not work, this article suggests a Border will do the trick:
A simple border will do, and by not setting its width and height
properties, it will shrink/grow based on the size of the TextBlock.
I've come up with the next solution , which works quite fine , but what i really would like to also have is a way to set a min font and max font size , so that if there is a single word , the font might need to be of some size, and if the text is too long , the font will be of a smaller size , all in a dynamic way.
code:
label.Text = label;
label.Measure(new Size(RenderSize.Width, RenderSize.Height));
border.Width = label.DesiredSize.Width + border.Padding.Left + border.Padding.Right + border.BorderThickness.Left + border.BorderThickness.Right;
border.Height = label.DesiredSize.Height + border.Padding.Top + border.Padding.Bottom + border.BorderThickness.Bottom + border.BorderThickness.Top;
and the xaml:
<Border BorderBrush="#ff000000" BorderThickness="2" CornerRadius="8" Visibility="Collapsed" Padding="5" Background="#bfff0000" Margin="10,0,10,200" VerticalAlignment="Bottom" x:Name="border">
<StackPanel>
<TextBlock FontSize="40" x:Name="pictureLabel" TextWrapping="Wrap" Foreground="#ff000000" />
</StackPanel>
</Border>
I have a little problem, I have a group item which I want to give a background image which it should scale keeping it's correct dimensions but by default it shows the image from the top left, I want the image to be centered.
Here is an illustration to further explain my problem. (the gray part is what is clipped)
And I have this XAML
<Image Source="/url/to/image.jpg" Stretch="UniformToFill"/>
I managed to solve my problem, I made the image larger than the container it was placed in and vertical aligned it in the center.
<Grid HorizontalAlignment="Left" Width="250" Height="125">
<Image Source="/url/to/image.jpg" Stretch="UniformToFill" Height="250" Margin="0" VerticalAlignment="Center"/>
</Grid>
The overflow of the image was invisible :)
In case the size of the source image is unknown in advance I had to use different trick:
<Border Width="250" Height="250">
<Border.Background>
<ImageBrush ImageSource="/url/to/image.jpg"
Stretch="UniformToFill"/>
</Border.Background>
</Border>
I wrote a behavior for Silverlight/Windows Phone that treats a similar situation. The picture I have to show may be larger or higher and I must display it in a square.
The behavior calculates the width/height ratio of both the container and the picture. Depending on which is the largest/highest, I resize the Image control to have this clipping effect with the parent control.
Here is a sample XAML to use with my behavior.
<Border Height="150" Width="150">
<Image Source="{Binding BitmapImage}" Stretch="UniformToFill"
HorizontalAlignment="Center" VerticalAlignment="Center">
<i:Interaction.Behaviors>
<b:FillParentBehavior />
</i:Interaction.Behaviors>
</Image>
</Border>
Here is an excerpt from the C# code. The full code can be found here: FillParentBehavior.cs
double width = this.AssociatedObject.Width;
double height = this.AssociatedObject.Height;
var parentSize = new Size(this.parent.ActualWidth, this.parent.ActualHeight);
var parentRatio = parentSize.Width / parentSize.Height;
// determine optimal size
if (this.AssociatedObject is Image)
{
var image = (Image)this.AssociatedObject;
if (image.Source is BitmapImage)
{
var bitmap = (BitmapImage)image.Source;
var imageSize = new Size(bitmap.PixelWidth, bitmap.PixelHeight);
var imageRatio = imageSize.Width / imageSize.Height;
if (parentRatio <= imageRatio)
{
// picture has a greater width than necessary
// use its height
width = double.NaN;
height = parentSize.Height;
}
else
{
// picture has a greater height than necessary
// use its width
width = parentSize.Width;
height = double.NaN;
}
}
}
this.AssociatedObject.Width = width;
this.AssociatedObject.Height = height;
I am trying to add some images to a FlipView using the following code:
for (int N = 1; N < 30; N++)
{
string name = String.Format(#"ms-appx:/Gallery/{0:00}.jpg", N);
Uri uri = new Uri(name);
BitmapImage img = new BitmapImage(uri);
MainFlipView.Items.Add(img);
}
but it only displays some texts. I defined the FlipView in my XAML:
<FlipView x:Name="MainFlipView">
</FlipView>
What should I do?
The text showing is a call to the ToString method of the BitmapImage because you have no DataTemplate defined. Define on:
<FlipView>
<FlipView.ItemTemplate>
<DataTemplate>
<Image Source="{Binding}" />
</DataTemplate>
</FlipView.ItemTemplate>
</FlipView>
Try this format for entering the file name
images\\Photos\\italia1.jpg
.here images and photos are obviously folders and italia1.jpg is the pic file. I have used this to set this image as the lock screen of the device. So maybe this is the format that could work for your flipview problem.
Your path to the image should look like this:
string name = String.Format(ApplicationData.Current.LocalFolder.Path + #"/Gallery/{0:00}.jpg", N);
Beginner here. I want to create a button in XAML which has text based on a variable in VB. I have the variable set in VB with
Dim ButtonName1 = "Test"
What will I need to do to make the button content display ButtonName1?
It is really quite easy. Your Button has a Name Property that you can use to reference it in your code behind, note in this example it is Button1 you just need to assign your string to the Button's Content Property
Xaml
<Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="10,10,0,0" Name="Button1" VerticalAlignment="Top" Width="75" />
xaml.vb
Dim ButtonName1 = "Test"
Button1.Content = ButtonName1
I am doing one project on kinect with windows SDK. I am trying to display the image on skeleton shoulder with the following code.
**
Xaml code
<Canvas Margin="250,0,0,0" Visibility="{Binding Path=Showcamera, Converter={StaticResource BVC}}" Background="Green" HorizontalAlignment="Stretch" VerticalAlignment="Top" Grid.Column="1" Grid.Row="1">
<Image MaxHeight="600" MaxWidth="950" x:Name="PART_KinectVideo" Visibility="{Binding Path=Showcamera, Converter={StaticResource BVC}}" />
<Canvas>
<Image RenderOptions.BitmapScalingMode="HighQuality" Visibility="{Binding Path=Showcamera, Converter={StaticResource BVC}}"
RenderOptions.EdgeMode="Aliased" Canvas.Top="60" Canvas.Left="350" Stretch="Uniform" x:Name="Jewel"/>
</Canvas>
Code Behind
var j1p = nui.MapSkeletonPointToDepth(closestSkeleton.Joints[JointType.ShoulderLeft].Position,DepthImageFormat.Resolution640x480Fps30);
Canvas.SetLeft(Jewel, j1p.X+90);
Canvas.SetTop(Jewel, j1p.Y-280);
by getting the j1p values i am trying to set the left and top position of the canvas for the Jewel image object.
Problem with the code is :
This is not correctly placing the image. When the user moves in the screen the image also moves out of body with left and right direction as user moves.
I need the image should be set to the position even when the user moves right or left.
How should I alter the code or is there any sample available to set the image in particular position of the kinect joints?
Maybe try this:
var left = (double)image.GetValue(Canvas.LeftProperty)
left += 90;
image.SetValue(Canvas.LeftProperty, left);
I wrote an app using that code and everything worked fine to me:)
