I'm trying to use the split button control described here:
http://mahapps.com/controls/split_dropdownbutton.html
I'm also using the MahApps resource pack with the icons collection. I want to re-size the control to a height of 40px, but the icon stays to its native height of 76px, resulting in it getting cropped, as shown below.
Any ideas how to get around this?
The SplitButton from MahApps.Metro has a property called IconTemplate. To this property you can assign a DataTemplate and there you can add almost arbitrary content, which will be put in place of the icon itself.
For example you could put a Rectangle control with fixed Height and/or Width. And setting its OpacityMask to your desired icon, will show the icon in smaller size.
In XAML it looks like this:
<controls:SplitButton Orientation="Horizontal">
<controls:SplitButton.IconTemplate>
<DataTemplate>
<Rectangle VerticalAlignment="Center" Height="35" Width="35" Fill="{DynamicResource BlackColorBrush}">
<Rectangle.OpacityMask>
<VisualBrush Visual="{StaticResource appbar_globe}" />
</Rectangle.OpacityMask>
</Rectangle>
</DataTemplate>
</controls:SplitButton.IconTemplate></controls:SplitButton>
controls is the alias for the MahApps.Metro-namespace and may differ in your project.

I have a StackPanel that needs to contain drawn background. Specifically, my StackPanel needs to have the ability to grow and the rectangle must grow with the StackPanel, but must remain pseudo-anchored to each side at a fixed position.
I've attempted to use the Canvas.Left, Canvas.Right, Canvas.Top and Canvas.Bottom attached properties, but so far they've not worked. Furthermore, this does seem to work when drawing within Canvas objects, just not when they are embedded within a VisualBrush set as a background. How can I accomplish drawing this resizable, rectangular background within my StackPanel?
Below is the state of my current code. I've tried various approaches but none seem to work.
My Code:
<StackPanel DockPanel.Dock="Right" Orientation="Vertical" VerticalAlignment="Center">
<StackPanel.Background>
<VisualBrush Stretch="None">
<VisualBrush.Visual>
<Canvas Background="Magenta" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
Rectangle Fill="#FFDDECF7" Canvas.Left="20" Canvas.Top="20" Canvas.Bottom="20" Canvas.Right="0"/>
</Canvas>
</VisualBrush.Visual>
</VisualBrush>
</StackPanel.Background>
...
</StackPanel>
This currently doesn't render anything. I set the canvas background to magenta just so I could see if it were drawing, and I'm not even seeing that. Other attempts have drawn the canvase, however, the blue rectangle is always stretched to fill the window, regardless of attached canvas property settings.
Sample:
The image below is a sample of what I want. Again, I'm using an ugly Magenta color to show the offset of the internal, blue rectangle. As the StackPanel grows or shrinks, the rectangle needs to be affixed to the top, left, right and bottom.
My suggestion is to place the stackpanel inside a grid:
<Grid DockPanel.Dock="Right" VerticalAlignment="Center" Background="Magenta">
<Rectangle Margin="20" Fill="#FFDDECF7"/>
<StackPanel Orientation="Vertical">
no background...
</StackPanel>
</Grid>
Wrap Canvas into a ViewBox, then work on a ViewBox. As far as I know Canvas doesn't support scalling too well.
This should be easy but I'm blanking out here.
I have a TextBlock inside of a Border control. The Width of the Border changes based on the length of the text in the TextBlock (updated in ViewModel). I would like this change in Width to be animated so that the width grows slowly (instead of jerky).
My Xaml:
<Border x:Name="myBorder" BorderBrush="Black" BorderThickness="1" HorizontalAlignment="Left" VerticalAlignment="Top">
<TextBlock x:Name="myTextBlock" HorizontalAlignment="Left" Text="Some Text"/>
</Border>
This is a perfect job for Expression Blend. You will need to create a Storyboard animation. Then once its created go into the code behind in visual studios and play it. You can tell it to play to a certain point based on how much text you have in your text block.
Here is a basic tutorial

I want to do something similar to Microsoft Powerpoint: I want to capture the current screen (or one grid from the current window), and then to set it as the content of the button (like powerpoint where there is a preview of the slides at the side bar).
What is the best way to do that? My current idea is to save it to PNG and then reload it as an image at the content of the button, but I'm sure there is a better way.
Thank you!
Try this:
<Grid>
<Viewbox
x:Name="Viewer"
Stretch="Uniform"
DataContext="{Binding ElementName=Thumbnail1, Path=Data}">
<Grid Width="224" Height="168" SnapsToDevicePixels="True" Margin="4,0,4,0">
<Grid.Background>
<VisualBrush Stretch="Uniform" TileMode="None" Visual="{Binding}" AlignmentY="Center"/>
</Grid.Background>
</Grid>
</Viewbox>
</Grid>
I was using saving as PNG approach in the beginning. Then I have found out the way as above. DataContext of the ViewBox is a canvas. I could create live previews of my screens this way however my screens were canvas objects.
I want to get this.
buttons http://www.shrani.si/f/X/6Y/24Jhn9D3/buttns.png
Everything works so far, buttons act as filter and are bind to the grid control.
All i want is the icons and counter on the button.
Whats the correct way of implementing those?
<ToggleButton x:Name="IsErrorShown" Margin="4" Width="100" Content="{lex:LocText Errors, Assembly=Client}">
I have tried adding image like this:
<ToggleButton x:Name="IsErrorShown" Margin="4" Width="100" Content="{lex:LocText Errors, Assembly=Client}">
<StackPanel>
<Image Source="Resources/Warning"/>
</StackPanel>
</ToggleButton>
but i get error that prop. Content is defined more then once.
A WPF Button (or ToggleButton) is a content control, into which you can put anything.
I haven't checked, but these buttons probably have a horizontal stack panel or a DockPanel, with an Image and then one or two TextBlocks. You could make a template for these, and also use binding to set the TextBlock Text content from your viewmodel.
Snoop ( http://snoopwpf.codeplex.com/ ) is a great tool for finding out how other people have built things in WPF.
The Adam Nathan WPF book is excellent, and if you don't have it you should get it. http://www.amazon.co.uk/Windows-Presentation-Foundation-Unleashed-WPF/dp/0672328917
Here's an example:
<ToggleButton Height="24" Width="100">
<DockPanel>
<Image Source="c:\\temp\\me.jpg" Margin="3"/>
<TextBlock Text="20 Errors"/>
</DockPanel>
</ToggleButton>
In WPF, if i put any controls in grid, if i resize the grid, it automatically resizes all the controls in it.But in label or textblock or any other text elements, all the control sizes will change but font size remains same, it will not change.
If font has to change as per grid size, What should be done?
You can achieve this by using a ViewBox. It will transform (not resize) your font (well, the control) depending on the control size.
Look at this here for more information;
<Viewbox Stretch="Uniform">
<TextBlock Text="Test" />
</Viewbox>
The following lines also give the expected result.
<Viewbox>
<TextBlock TextWrapping="Wrap" Text="Some Text" />
</Viewbox>
