So I'm pretty new to WPF and I'm having trouble with the layout of my Window. Currently I have a WPF application with a Grid defined as such:
<Grid.RowDefinitions>
<RowDefinition Height="23" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
In the very top row, spanning two columns, I have a Menu. In the second row I have some Labels in the first column and an Image and a WindowsFormsHost in the second, finally, in the third row I have a graphing control in the second column. By default, I set the size of the Image and WFH to 570 x 413. Now, I'd like for both the Image and WFH to expand when my Window is resized such that they maintain the same relative (to the Window) size. (I actually would like the same to happen to my graphing control as well, but I can probably figure that one out if I can get the others. I cannot for the life of me figure out what setting I need to turn on/off or what I might need to bind or whatever in order to make this happen. Any help is greatly appreciated!
Thanks!
Have you tried:
<RowDefinition Height="*" />
Make sure to assign your Grid.Row within your image or control, but do not sign the controls height/width properties. The control should autosize with expansion.
Update
Did a quick test to make sure this works.
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="23"/>
<RowDefinition Height="*"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Label Grid.Row="0" Content="Example"/>
<Image Grid.Row="1" Source="c:\Example.jpg"/>
<Label Grid.Row="2" Content="Example2"/>
</Grid>
The image expands with the application based on the image's proportions. It does expand, but it keeps it's dimensions along with the full image in view. If you were to change the rowdefinition from ***** to Auto, you will notice that the image will expand, but it will expand past your view. Meaning you will not always see the full image.
I would suggest making a simple application like above, and playing with constraints to figure out what each does.
You need to show more information in your description, because all of the properties of the Grid and of the Image, etc. will factor into the layout.
However, you probably want to look at the HorizontalAlignment and VerticalAlignment properties of your Grid and of your Image, as well as the Stretch property of the Image. Also, you don't want to specify a fixed size for the image (you can specify a MinWidth and a MinHeight if you want them to be a certain size when starting up).
Here's a quick example that shows a grid filling a window, with a scaling image.
<Grid HorizontalAlignment="Stretch"
VerticalAlignment="Stretch">
<Grid.RowDefinitions>
<RowDefinition Height="23" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Label Grid.Column="0" Grid.Row="0" Grid.ColumnSpan="2" Content="First Row" />
<Label Grid.Column="0" Grid.Row="1" Content="Column 0, Row 1" />
<Image Grid.Column="1" Grid.Row="1"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
Source="Resources\ExamplePicture.png"
Stretch="Uniform" />

I am trying to have a canvas that takes all window size upon resizing, and a button over it, in the bottom left corner, but which resizes with the window(up to some max size, maybe), and the margin from the button to left and bottom resizes with the window as well.
I have tried to achieve it with a grid like this:
<Canvas Background = "LightGray" x:Name="PaintCanvas"
VerticalAlignment="Stretch" HorizontalAlignment="Stretch"
Height="auto" Width="auto">
<Grid ShowGridLines="True">
<Grid.RowDefinitions>
<RowDefinition Height="8*" />
<RowDefinition Height="20*" />
<RowDefinition Height="62*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="8*" />
<ColumnDefinition Width="5*" />
<ColumnDefinition Width="87*" />
</Grid.ColumnDefinitions>
<Button x:Name="testBut" Content="TEST"
Grid.Column="1" Grid.Row="1"
MaxHeight="150" MaxWidth="50"
/>
</Grid>
</Canvas>
Edit: it seems that i have to fill the canvas with the grid.
So, here's how i handled it:
Added my grid(with predefined empty cells that serve as margins) as the only child of Window. Then added Canvas as child of grid, but specified it to span across all its rows and columns - filling whole grid(and Window):
<Canvas Background="WhiteSmoke" x:Name="PaintCanvas"
VerticalAlignment="Stretch" HorizontalAlignment="Stretch"
Grid.RowSpan="3" Grid.ColumnSpan="3"/>
Finally,i put the button in needed cell
I am using a GridView to display some products.
When I set the DataTemplate I use Width and Height with static values and define some rows for the data I want to display.
<Grid Width="97" Height="180"">
<Grid.RowDefinitions>
<RowDefinition Height="80"/>
<RowDefinition Height="20"/>
<RowDefinition Height="*"/>
The first row is for a 80x80 image and the second for the price.So far, so good.
Then I face the problem that even if the data shown (with the name of the product) in the last row, with a TextBlock, is just one line, the GridViewItem takes the value defined from the height property.
Is there a way for the height to adjust on TextBlock's Text. I tried setting Height to Auto, not including at all for the Grid and the TextBlock but then the text is not appearing whole on the screen.
I have a feeling what you want is the text to wrap around. You can achieve this by setting the text to wrap, like in the code demonstrated below:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="80"/>
<RowDefinition Height="20"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid Grid.Row="0" Background="Red" />
<Grid Grid.Row="1" Background="Blue" />
<TextBlock Grid.Row="2" TextWrapping="Wrap" Text="This is some text which will not fall off the edge because it is set to wrap around, and will continue filling down until the end of the screen because the grid is set to auto" />
</Grid>
I'm developing an application using WPF by c#.
I have 2 frames next to each other. The above will not change and just updated(like Facebook toolbar).
The bottom frame will change by clicking on some buttons. (it is something like masterpage in ASP).
I don't want to set a height and width for window or for frames. The problem is when I make the window full screen there is a space between two frames.
However none of the vertical/horizontal alignment stretch does not work.
<window>
<Frame VerticalAlignment="Top" Background="Crimson" />
<Frame VerticalAlignment="Bottom" Background="Black"
/>
</Window>
I want to create something like the this site as you see. the notify section and the main page.
EDIT:
i can put them next to each other just by set the height, but when i make full the window the heights stay and the yellow space becomes appear, so i want to find a way to put them Exactly next to each other in every window size.
As Mitch noted in the comments, you could place the two frames in a grid instead, and let the grid size the items.
<Window>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Frame Grid.Row="0" Background="Crimson" />
<Frame Grid.Row="1" Background="Black" />
</Grid>
</Window>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Frame Grid.Row="0" Background="Crimson" />
<Frame Grid.Row="1" Background="Black" />
</Grid>
I want to fetch the positions of controls within a page in windows store apps in pixels.
It would be nice to be able to do it for an arbitrary control, however for the moment just figuring out how to do it for a button would be fine!
I've tried looking at margins, but they seem to often have no relation to the actual position when mechanisms like Grid.Row="x" or HorizontalAlignment="Center" are used in the Xaml or set programatically. I would need this method to work whatever the method of positioning the control is.
Thanks in advance!
EDIT:
I'm testing by setting up a UI:
<Grid x:Name="grid" Style="{StaticResource LayoutRootStyle}">
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Button x:Name="test" Grid.Row="1" Grid.Column="1" HorizontalAlignment="Center" VerticalAlignment="Center" Content="test"/>
</Grid>
and then modifying the 'Grid.Column', 'Grid.Row' and Alignment characteristics.
You can get position of control using transform object.
<Button x:Name="btn" Content="Button" Margin="131,339,0,391" />
void BlankPage4_Loaded(object sender, RoutedEventArgs e)
{
var trans = test.TransformToVisual(null);
var point = trans.TransformPoint(new Windows.Foundation.Point());
}
Critical problem here. In my case i assemble the below code for my application. Unfortunately, it creates the bigger problem in layout. Even we put RowDefinitions with Auto, it does not consider the RowHeight and goes underneath to the Bottom of the Windows Phone emulator.
<Grid>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid Grid.Row="0" x:Name="firstGrid" Tap="FirstGrid_OnTap"/>
<Grid Grid.Row="1" Visibility="Collapsed">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Button Content="A"/>
<Button Grid.Column="1" Content="B"/>
</Grid>
</Grid>
</Grid>
On loading of the page, it fills the firstGrid with the ImageBrush. Hence whenever user taps on the firstGrid, It will just insert one more row to the Grid by enabling the visibility of the second grid. This second grid will have couple of buttons. I astonished when i see the second grid because it hides in the bottom of the emulator. Even my hundred of different attempts , i am not able dig into the main problem which actually it has. Any help is much appreciated.
As per my understanding u need to make this change in code first row should be auto and second *.
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
