I have a TextBox control and I would like to be able to set a background image and a background color.
Currently I can set one, or the other but not both. When I try to set both simultaneously I receive a "The property 'Background' is set more than once" error.
Here is the code I used:
<TextBox Name="tbImageTextBox">
<TextBox.Background>
<ImageBrush ImageSource="/Resources/Images/image.png"
AlignmentX="Right" Stretch="None"/>
<SolidColorBrush>#FF8D8A8A</SolidColorBrush>
</TextBox.Background>
</TextBox>
I have also attempted to set the background color in the style for the TextBox and the image in the <TextBox.Background>, but the color is ignored.
Use the grid resource for background as needed. Same resource can be used for multiple textboxes.
<Grid>
<Grid.Resources>
<ImageBrush x:Key="img" ImageSource="Blue hills.jpg"></ImageBrush>
<SolidColorBrush x:Key="brownBrush" Color="Brown"></SolidColorBrush>
</Grid.Resources>
<TextBox x:Name="test" Background="{StaticResource img}" Width="100" Height="40" />
</Grid>
I ended up putting the TextBox into a grid with the Background color set and applying the background image to the TextBox itself as using VisualBrush and DrawingBrush stretched my image or only applied the background color to the image - not the rest of the TextBox.
You will need to combine the colour and the image in a single Brush instance, you could use a DrawingBrush or a VisualBrush containing an Image control with your image and the Background set to the colour for example.
You probably want either a VisualBrush or a DrawingBrush. More information on those can be found at MSDN here. Something like this might get you started:
<Rectangle Width="75" Height="75">
<Rectangle.Fill>
<VisualBrush TileMode="Tile">
<VisualBrush.Visual>
<Grid>
<Image BaseUri="somepic.png" />
<Rectangle Brush="FF8D8A8A" />
</Grid>
</VisualBrush.Visual>
</VisualBrush>
</Rectangle.Fill>
</Rectangle>

I want to show some text information at the top/left of HelixViewport3D like "ShowCameraInfo" does, which display camera information at the bottom/left of the Viewport. BillboardTextVisual3D requires a 3D point, but what I want is just like TextBlock on Canvas, which just need a 2D coordinate.
I can use TextBlock, but it cannot be captured as part of HelixViewport3D.
Any idea?
Literally a Textblock placed over the HelixViewport3D should be what you need.
There is only one problem: Viewport will not recognize if you try to manipulate the camera by initiating the mouse click on the Stackpanel.
<Grid>
<hx:HelixViewport3D>
<hx:DefaultLights/>
<hx:CubeVisual3D SideLength="7"/>
<hx:CubeVisual3D SideLength="5" Fill="Red" Center="-5,3,0"/>
</hx:HelixViewport3D>
<StackPanel Margin="5" HorizontalAlignment="Left" VerticalAlignment="Top">
<StackPanel.Background>
<SolidColorBrush Color="#FFB6B6B6" Opacity="0.4"/>
</StackPanel.Background>
<TextBlock Text="asdhfasdvfmnas" Margin="5,2"/>
<TextBlock Text="mvcbnxcvjhbkdaf" Margin="5,2"/>
<TextBlock Text="vbkjsdvj" Margin="5,2"/>
</StackPanel>

I have a MetroAnimatedSingleRowTabControl from MahApps Metro. I want to change the header's foregorund color from blue (defined by the template) to white.
This is what I have got:
<Grid x:Name="Body" Grid.Row="1" Margin="20,0,20,0">
<controls:MetroAnimatedSingleRowTabControl>
<controls:MetroAnimatedSingleRowTabControl>
<controls:MetroTabItem Header="Server"/>
</controls:MetroAnimatedSingleRowTabControl>
</controls:MetroAnimatedSingleRowTabControl>
</Grid>
I want to let the Server Header to appear in white.
The colors are set in the triggers towards the end of the TabItem template.
Once you got the Keys you can overwrite the resource bindings
<Grid x:Name="Body" Grid.Row="1" Margin="20,0,20,0">
<Controls:MetroAnimatedSingleRowTabControl>
<Controls:MetroAnimatedSingleRowTabControl.Resources>
<SolidColorBrush x:Key="AccentColorBrush" Color="Red"/>
<SolidColorBrush x:Key="HighlightBrush" Color="Orange"/>
</Controls:MetroAnimatedSingleRowTabControl.Resources>
<Controls:MetroTabItem Header="Server"/>
</Controls:MetroAnimatedSingleRowTabControl>
</Grid>
We have a design requirement such that transparent buttons (with white text) are overlayed on a scenic background image. But here's the hard part, and my dilemma...
While the background image should be clear and visible OUTSIDE the image borders, the area INSIDE the buttons (the overlayed area) should be a blurred area of the background image. The idea is to make it easier for users to see the white text inside the button.
I'm a novice in XAML and even more unfamiliar with how to perform such complex styling. I have a starting point for the overlay layout, but this code does not attempt to solve the problem. It's simply a button over an image.
Any ideas or help on how to blur the area under the image?
<Grid Margin="0,0,0,12" Visibility="{Binding SignedIn, Converter={StaticResource BooleanToVisibilityConverter}, ConverterParameter=False}">
<Image Source="backgroundImage.png" Height="136" Stretch="Fill" HorizontalAlignment="Stretch" />
<StackPanel VerticalAlignment="Center" HorizontalAlignment="Center">
<Button x:Uid="SignInBtn" Content="SIGN IN" Style="{StaticResource TransparentButtonStyle}" HorizontalAlignment="Center" Command="{Binding SignInCommand}" IsEnabled="{Binding LoadingResults, Converter={StaticResource NotBoolConverter}}" />
</StackPanel>
</Grid>
There's no straightforward way to do this in a Windows Phone 8.1 app. Image effects are not supported in either Windows Phone Silverlight or in Windows.UI.Xaml.
The typical and easy solution would be to dim (rather than blur) the image by setting the Button's background to a partially transparent brush.
<Button Background="#7F000000" </Button>
If you want to put a bit more work into it you can crop the area of the bitmap behind the button, run your blur transform on it (take a look at the Lumia Imaging SDK) and then set the new, blurred image to the button.
Consider using Effects.
In addition, see if you can leverage this example:
<Style TargetType="Window">
<Setter Property="Background">
<Setter.Value>
<VisualBrush>
<VisualBrush.Visual>
<Image Source="Images\myImage.png">
<Image.Effect>
<BlurEffect Radius="20"/>
</Image.Effect>
</Image>
</VisualBrush.Visual>
</VisualBrush>
</Setter.Value>
</Setter>

I have been using a RichTextBox to show FlowDocuments in a WPF app, but I found that there is something called FlowDocumentReaderwhich gives me alot of functionality for free. The problem is that while the background in the RichTextBox was shown as white, it is now completely transparent.
I have tried setting the Backgroundproperty, but that only changes the toolbar at the bottom.
<FlowDocumentReader Grid.Row="1" Grid.Column="1" Name="rtbShowDoc" Margin="20, 0" Background="White">
<FlowDocumentReader.Effect>
<DropShadowEffect BlurRadius="10" Color="Black" ShadowDepth="3" />
</FlowDocumentReader.Effect>
</FlowDocumentReader>
I can do an ugly fix with a DockPanel, but that does not seem like the right way to do it.
<DockPanel Grid.Row="1" Grid.Column="1" Margin="20, 0" Background="White">
<DockPanel.Effect>
<DropShadowEffect BlurRadius="10" Color="Black" ShadowDepth="3" />
</DockPanel.Effect>
<FlowDocumentReader Grid.Row="1" Grid.Column="1" Name="rtbShowDoc" Background="White">
</FlowDocumentReader>
</DockPanel>
How can I set the background of a FlowDocumentReader?
EDIT: Added screenshot of running application. As you can see the dropshadow effect is applied to all text inside the FlowDocument.
Try setting the background of the FlowDocument
FlowDocument.Background Property
In C#:
FlowDocument.Background = Brushes.Red;
The problem i have is how to use both the solid brush and imagebrush tags in listview.bakcground? I have set an image as background in listview but i m not able to set any color to the background?
<ListView.Background>
<ImageBrush ImageSource="Images\ViewIcons\cls.png" Opacity="0.05" />
</ListView.Background>
If you will set the same property i.e Background then later will overwrite the value of former so do it like this
<Border Background="Red">
<ListView >
<ListView.Background>
<ImageBrush ImageSource="Images\Q3.png" Opacity=".05" />
</ListView.Background>
</ListView>
</Border>
I hope this will give you an idea.
