I have a WPF application. To make the full screen visible on all screen sizes, I have implemented MinHeight, MinWidth & HorizontalAlignment="Stretch" VerticalAlignment="Stretch" in Window & Containers too. I am facing some problems when the app runs on Lower Resolution screens. The window gets cut from the right side of the screen - this doesn't show Min, Max, Close btns also on top right.
If I add layout code in then the window is proper in all resolutions, but it makes blank space above the Menubar and below end. On removing , their is no space and all is well, but right side gets cut in Low Resolution screens. And with ViewBox, space above and below the layout. My XML code is like follows :
CODE UPDATED
<Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch" >
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<!-- MENU BAR -->
<Menu Grid.Row="0" x:Name="myMnus" VerticalAlignment="Top" Cursor="Hand" HorizontalAlignment="Stretch" IsMainMenu="True" Grid.ColumnSpan="2">
.............
</Menu>
<ToolBarTray HorizontalAlignment="Stretch" Background="White" Margin="0,19,114,0" VerticalAlignment="Top" Grid.ColumnSpan="2" >
..............
<ToolBarTray>
<TabControl Grid.Row="1" Name="tabControl1" HorizontalAlignment="Left" Margin="0,3,0,0" VerticalAlignment="Top"
TabStripPlacement="Bottom" Grid.RowSpan="2" BorderThickness="4,25,4,1" FontSize="13">
</TabControl>
<TabControl Grid.Row="2" Name="tabControl4" HorizontalAlignment="Left" Margin="0,323,0,0" VerticalAlignment="Stretch"
TabStripPlacement="Bottom" BorderThickness="4,25,4,1" FontSize="13" Background="White" Width="227">
</TabControl>
<TabControl TabStripPlacement="Bottom" MinHeight="415" MinWidth="480" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Grid.Row="1" Grid.Column="1" Name="tabChildContainer" Margin="227,3,207,0" BorderThickness="4,25,4,1" Grid.RowSpan="2" >
</TabControl>
</Grid>
I thought by using Stretch in HorizontalAlignment and VerticalAlignment along with MinWidth and MinHeight, that it would occupy all available space horizontally and Vertically. But tabChildContainer TabControl doesn't go to the right end corner which it should go based on the code.
This is where your problem starts:
<Grid.ColumnDefinitions>
<ColumnDefinition Width="762.976"/>
<ColumnDefinition Width="751.024"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
Anytime that you set exact pixel sizes in your UI, you're asking for exactly these kinds of problems. Setting exact sizes for sections of your application was more of a WinForms thing... WPF has numerous controls that can resize your content for you... you're using one, the Grid... just incorrectly.
Secondly, it is very unusual to use a ViewBox on your whole UI... it is not going to help you. Your best bet is to simply remove it and all of your hard-coded dimensions and make full use of the "*" and "Auto" values in your Grid. When the controls resize themselves (or a Grid resizes them) in this way, it really doesn't matter what resolution a user is using.

I write an XAML application and I have a problem with the size of text. How can I make the texts look complete but with the same size? (make it responsive).
This is a small example of my XAML code:
<!-- (0, 0) Availability -->
<Grid Grid.Row="0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Viewbox Stretch="Uniform">
<Grid Grid.Column="0">
<TextBlock Style="{StaticResource OeeText}">Disponibilidad</TextBlock>
</Grid>
</Viewbox>
<Grid Grid.Column="1">
<TextBlock Style="{StaticResource OeeValues}">100%</TextBlock>
</Grid>
</Grid>
In the Window App, the text shows as:
How can I make all three texts look the same size?
Thanks )
You may define the size of a textBox in a responsive manner using the ViewBox Component but you have to use it inside the grid , in order to wrap the textBox Control
<Viewbox Stretch="Uniform" MaxWidth="200" MaxHeight="200" MinWidth="100" MinHeight="100">
<TextBox x:Name="MyTextBox" />
</Viewbox>
You may also control the size by setting its max/min of width and height as mentioned in the docs
I have a WPF application and I'm trying to get the elements positioned correctly. There are just four elements, so it should be pretty straight-forward, but I just can't get it working.
One wrinkle is that the window resizes itself to (about) the size of the desktop window when it appears, so it doesn't have a fixed size.
The elements are supposed to be stacked from top to bottom, so a Stack Panel seemed natural. But The third element has to take up all the remaining space that the top two and bottom ones don't. No matter what I tried, it either took up too much space, or too little. I could only seem to get it working if I gave it a concrete pixel size which, as explained above, won't work.
The latest thing I've tried is a Dock Panel. While it looks correct in the Visual Studio designer, when executed, the third element--a Canvas--completely covers the bottom element.
My XAML:
<DockPanel>
<Button x:Name="btnClose" DockPanel.Dock="Top" Content="X"
HorizontalAlignment="Right" Margin="0,5,5,0" VerticalAlignment="Top"
Width="Auto" Height="Auto" Background="Black"
Foreground="White" Click="btnClose_Click"/>
<Label x:Name="lblTitle" DockPanel.Dock="Top" Content="My Title"
HorizontalAlignment="Center" VerticalAlignment="Top" Width="Auto"
Foreground="White" FontWeight="Bold" FontSize="22"/>
<Label x:Name="lblControls" DockPanel.Dock="Bottom" Content="Placeholder"
HorizontalAlignment="Center" VerticalAlignment="Bottom" Width="Auto"
Height="Auto" Foreground="White" FontWeight="Bold" FontSize="22"/>
<Border x:Name="CanvasBorder" BorderBrush="White" BorderThickness="5" >
<Canvas x:Name="cvsChart" Grid.Row="0" HorizontalAlignment="Stretch"
VerticalAlignment="Top" Width="Auto">
</Canvas>
</Border>
</DockPanel>
Any idea about how to get that Canvas to stretch and fill all the space the other three don't take?
UPDATE
Since #Peter Duniho pretty much proved to me that the code worked, I tried an experiment and removed the resizing code I have in place for when the window appears. Taking it out, the window appears absolutely correctly. This is what I do to resize it to (mostly) the desktop size:
public const int WINDOW_OFFSET = 10;
...
int screenWidth = (int)System.Windows.SystemParameters.PrimaryScreenWidth;
int screenHeight = (int)System.Windows.SystemParameters.PrimaryScreenHeight;
// center this window in desktop
Width = screenWidth - WINDOW_OFFSET;
Height = screenHeight - WINDOW_OFFSET;
Left = WINDOW_OFFSET/2;
Top = WINDOW_OFFSET/2;
So I did some poking around, and found a comment here on the 'Stack that said to get the WorkArea instead of the PrimaryScreenHeight. I tried that and voila!, the whole application window appears.
int screenWidth = (int)System.Windows.SystemParameters.WorkArea.Width;
int screenHeight = (int)System.Windows.SystemParameters.WorkArea.Height;
As it turns out, the bottom row was displaying, I just couldn't see it because it appeared below the bottom of the screen. Now I can see it, and I'm back to development heaven!
Thanks to everyone for their input!
There are a number of possible approaches to this. One of the most straightforward is to contain your elements in a Grid and set all but the third row height to Auto:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Button x:Name="btnClose" Content="X" Grid.Row="0"
HorizontalAlignment="Right" Margin="0,5,5,0" VerticalAlignment="Top"
Width="Auto" Height="Auto" Background="Black"
Foreground="White" Click="btnClose_Click"/>
<Label x:Name="lblTitle" Content="My Title" Grid.Row="1"
HorizontalAlignment="Center" VerticalAlignment="Top" Width="Auto"
Foreground="White" FontWeight="Bold" FontSize="22"/>
<Label x:Name="lblControls" Content="Placeholder" Grid.Row="3"
HorizontalAlignment="Center" VerticalAlignment="Bottom" Width="Auto"
Height="Auto" Foreground="White" FontWeight="Bold" FontSize="22"/>
<Border x:Name="CanvasBorder" BorderBrush="White" BorderThickness="5" Grid.Row="2">
<Canvas x:Name="cvsChart" Grid.Row="0" HorizontalAlignment="Stretch"
VerticalAlignment="Top" Width="Auto">
</Canvas>
</Border>
</Grid>
The default setting for a grid's row definition height is "*", which says to distribute all of the remaining space among all the rows with that setting. With only one row using that setting, it gets all of the leftover space.
This produces a window that looks like this:
(I set the window background to Gray so that your white text and border would be visible.)
Another option would in fact be to use DockPanel. It appears to me that the main problem in your attempt is that you set the lblControls element to DockPanel.Dock="Bottom" when it should be Top instead. When I change it to Top, it seems to work fine for me.
Based on your comment below, it seems you actually did want lblControls to be set to DockPanel.Dock="Bottom", and in fact the code you posted seems to also do what you want. It's not clear to me what is different from what the code you posted does and what you want it to do. It would be better if you would provide a good Minimal, Complete, and Verifiable code example that reliably reproduces the problem.

I have this in my XAML
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="0.4*"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="0.4*"/>
</Grid.ColumnDefinitions>
<Grid Grid.Column="1">
<Grid.RowDefinitions>
<RowDefinition Height="0.5*"/>
<RowDefinition Height="*"/>
<RowDefinition Height="0.5*"/>
</Grid.RowDefinitions>
<Grid Grid.Row="1" >
<TextBlock HorizontalAlignment="Center" TextWrapping="Wrap" Text="Hello there and welcome!" />
</Grid>
</Grid>
</Grid>
The problem I'm facing is that the TextBlock will remain the same FontSize on all screen sizes, so when the screen is small, its easy to read but as the screen gets bigger its harder to read.
How do I keep it at a nice FontSize so it's readable from all screen sizes? Is there a way of increasing the font size as the screen expands?
You can wrap it inside the ViewBox
<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation">
<Viewbox>
<TextBlock HorizontalAlignment="Center" TextWrapping="Wrap" Text="Hello there and welcome!" />
</Viewbox>
</Window>
WPF fonts are DPI aware, so they'll be the same size regardless of resolution. A viewbox will allow you to scale everything down to fit, although in my experience it typically results in everything looking too small, especially if it's been designed on a desktop and then viewed on a laptop. What I do myself is create two themes and choose the appropriate one based on physical display size (i.e. product of DPI and resolution). Not sure if it's the best solution, but so far it seems to be working.
NOTE: This is one of the first time I'm using WPF.
I am trying to align a certain control, let's say a button for now, in the bottom right corner. But when I debug my application, it misses 8 pixels to the bottom and right. I will attach 2 pictures to show you what happens.
How do I keep the button in place?
My XAML code:
<Window x:Class="Plugin_Manager.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Plugin Manager" Height="350" Width="525" Loaded="Window_Loaded_1">
<Grid x:Name="GridMain">
<Button Content="Refresh" Margin="432,288,0,0" VerticalAlignment="Top" HorizontalAlignment="Left" Width="75"/>
<ListView HorizontalAlignment="Left" Height="273" Margin="10,10,0,0" VerticalAlignment="Top" Width="497">
<ListView.View>
<GridView>
<GridViewColumn/>
</GridView>
</ListView.View>
</ListView>
</Grid>
If you choose to use Grid layout you should try to avoid placing objects via Margin. Margin should be used to create buffer around an object, not move it to a specific point in the window. Use the layout manager's power to your advantage!
Here is a Grid example that does what you are looking for.
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<ListView Grid.Row="0" />
<Button Grid.Row="1" HorizontalAlignment="Right" Content="Push Me" />
</Grid>
I would also read up on Layout Manager in WPF. There are several; each having its own advantages & disadvantages.
Here is a DockPanel version.
<DockPanel>
<Button DockPanel.Dock="Bottom" HorizontalAlignment="Right" Content="Push Me" />
<ListView />
</DockPanel>
To create your buffer between the button and the window chrome you could do a few different things:
<Grid Margin="10"> will apply a 10 pixel space between all content and the window chrome on all side.
<Grid Margin="0,0,10,10"> would indent all content, but only on the right & bottom.
<Grid Margin="10,0,10,10"> indents all around, except the top (I commonly do this one, with a different margin value).
<Button Margin="0,0,10,10"> would indent only the button from the chrome (this is the direct answer to your comment question).
Replace the Grid above with DockPanel for the second example, or whatever other Layout Manager you are using.
A usability side note: Your confirmation buttons (I'm assuming your button will be an Ok/Cancel type button) should not be indented differently from the rest of your content. All controls that butt up against the right margin should do so at the same point (i.e., you can draw a vertical line down the right side of them all).
So, using your question's example: your button should not be indented 10 pixels to the right while your list box is not. Keeping things lined up will improve the overall look to your application.
(this ends my "usability and look-and-feel is important" side note) :)
<Button VerticalAlignment="Bottom" HorizontalAlignment="Right" Margin="5"/>
Some code example will help. Try using the alignment in xaml for your button as shown below. Ensure that the margins on the button are 0.
<Button Margin="0" HorizontalAlignment="Right" VerticalAlignment="Bottom"/>
Looking at the sample code, it is your margins and the alignment you have that are probably causing that.
Just some pointers that may help. Instead of using large margins to align the controls, I find it much easier to work with Column and Row definitions on the grid. This way you can align your controls using the grid and they will size properly as you resize your window. I attached an example in hopes it helps in your new adventures with WPF!
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="150"/>
<ColumnDefinition Width="150"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<TextBlock Grid.Column="0" Grid.Row="0" Text="Version Date" Margin="3" VerticalAlignment="Center"/>
<TextBlock Grid.Column="0" Grid.Row="1" Text="{Binding DateSubmitted}" Margin="3"/>
<TextBlock Grid.Column="1" Grid.Row="0" Text="Report" Margin="3" VerticalAlignment="Center"/>
<TextBlock Grid.Column="1" Grid.Row="1" Text="{Binding ReportName}" Margin="3"/>
</Grid>
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" />
