I am trying to increase the height of a row in my grid to the number of items I add in XAML, I'll draw it out to explain and hopefully someone can help me with my problem:
How about:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="43"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="54"/>
</Grid.RowDefinitions>
<Button Grid.Row="0" Content="Title"/>
<StackPanel Grid.Row="1" Orientation="Vertical">
<TextBlock Text="Scenario 1" />
<TextBlock Text="Scenario 2" />
<TextBlock Text="Scenario 3" />
</StackPanel>
<Button Grid.Row="2" Content="Add scenario"/>
</Grid>
This will not grow the window, but just the Grid itself.

I searched around and didn't find similar question on the forum. I have the following WPF code.
<Window x:Class="WpfApp5.MainWindow"

Title="MainWindow" Height="238.788" Width="406.407">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<TextBox TextWrapping="Wrap" Text="TextBox1 should be resized while moving the GridSplitter"/>
<GridSplitter HorizontalAlignment="Stretch" Height="5" Grid.Row="1" />
<StackPanel Grid.Row="2" Orientation="Horizontal" Background="Black">
<TextBlock Padding="5" Text="I want this black section have fixed height while moving the GridSplitter" Foreground="Aqua" VerticalAlignment="Center" />
</StackPanel>
<TextBox Grid.Row="3" TextWrapping="Wrap" Text="TextBox2 should be resized while moving the GridSplitter"/>
</Grid>
</Window>
When the user drags the grid splitter, only the two textbox should be resized. But what I got is like this:
How can I fix this?
Move the StackPanel and the second TextBox into a single Panel:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<TextBox TextWrapping="Wrap" Text="TextBox1 should be resized while moving the GridSplitter"/>
<GridSplitter HorizontalAlignment="Stretch" Height="5" Grid.Row="1" />
<DockPanel Grid.Row="2">
<StackPanel Orientation="Horizontal" Background="Black" DockPanel.Dock="Top">
<TextBlock Padding="5" Text="I want this black section have fixed height while moving the GridSplitter" Foreground="Aqua" VerticalAlignment="Center" />
</StackPanel>
<TextBox TextWrapping="Wrap" Text="TextBox2 should be resized while moving the GridSplitter"/>
</DockPanel>
</Grid>
It's easy, set VerticalAlignment="Center" by the ´StackPanel´
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<TextBox TextWrapping="Wrap" Text="TextBox1 should be resized while moving the GridSplitter"/>
<GridSplitter HorizontalAlignment="Stretch" Height="5" Grid.Row="1" />
<StackPanel Grid.Row="2" Orientation="Horizontal" Background="Black" VerticalAlignment="Center">
<TextBlock Padding="5" Text="I want this black section have fixed height while moving the GridSplitter" Foreground="Aqua" VerticalAlignment="Center" />
</StackPanel>
<TextBox Grid.Row="3" TextWrapping="Wrap" Text="TextBox2 should be resized while moving the GridSplitter"/>
</Grid>
I found that the problem is not because GridSplitter can only split two before and after siblings, it's the wrong RowDefinition! In the code snippet of the question, the first and forth RowDefinition are set to Height="*", which force them to split the additional space evenly. That's why when you drag the splitter and the first and forth row always keep the same height. If I change them according to the following setting, it just works as expected.
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="150" />
<RowDefinition Height="5" />
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<TextBox TextWrapping="Wrap" Text="TextBox1 should be resized while moving the GridSplitter" />
<GridSplitter HorizontalAlignment="Stretch" Height="5" Grid.Row="1" />
<StackPanel Grid.Row="2" Orientation="Horizontal" Background="Black">
<TextBlock Padding="5" Text="I want this black section have fixed height while moving the GridSplitter"
Foreground="Aqua" VerticalAlignment="Center" />
</StackPanel>
<TextBox Grid.Row="3" TextWrapping="Wrap" Text="TextBox2 should be resized while moving the GridSplitter" />
</Grid>
So no need to nest any more.
I have a Group Box that contain a Stack Panel that contains a Combo Box (A) and a Text Box. And I have another Stack Panel (B) that contains a combo Box and a Label.
I would place the Combo Box B on the same level as Combo Box A (same y) using xaml code.
Please note that the GroupBox and and the Stack Panel(B) are placed in a grid in the same row, different columns.
I'm trying to bind the y coordinate of the Combo Box (B) to the y coordinate of the Combo Box (A).
Where I can find the coordinates info of wpf controls in the Visual Studio properties window ?
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<GroupBox Name="AGroupBox" Grid.Row="1" Grid.Column="0" >
<GroupBox.Header>
<Label Content="GroupBox" FontWeight="Bold" />
</GroupBox.Header>
<StackPanel Grid.Row="1" Grid.Column="0" Orientation="Horizontal">
<ComboBox x:Name="ComboBoxA" Width="100" Height="25" VerticalAlignment="Center"/>
<TextBlock x:Name="TextBlockA" Width="150" VerticalAlignment="Center" Margin="10,0,0,0" Text="This a Test" />
</StackPanel>
</GroupBox>
<StackPanel Grid.Row="1" Grid.Column="1" HorizontalAlignment="Left">
<Label x:Name="LabelB" Content="LabelB" />
<ComboBox x:Name="ComboBoxB" Width="150" Height="25"/>
</StackPanel>
</Grid>
a close equivalent of using y-coordinate would be using Margin property ... but it is going to break after the first resize attempt.
i think, it is possible to update Margin on resizes, but i would start with a more complex layout, like this:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<!--additional Grid used to position comboBoxes on the same height-->
<Grid Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="2">
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition Height="Auto"/>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<!--group box is used as cover for the 1st column-->
<GroupBox Name="AGroupBox"
Grid.Row="0" Grid.RowSpan="3" Grid.Column="0" >
<GroupBox.Header>
<Label Content="GroupBox" FontWeight="Bold" />
</GroupBox.Header>
</GroupBox>
<!--stack panel with ComboBoxA is centered vertically in the 1st column-->
<StackPanel Grid.Row="1" Grid.Column="0"
Margin="5,0"
Orientation="Horizontal">
<ComboBox x:Name="ComboBoxA" Width="100" Height="25" VerticalAlignment="Center"/>
<TextBlock x:Name="TextBlockA" Width="150" VerticalAlignment="Center" Margin="10,0,0,0" Text="This a Test" />
</StackPanel>
<!--ComboBoxB is centered vertically in the 2nd column-->
<ComboBox x:Name="ComboBoxB"
Grid.Row="1" Grid.Column="1"
VerticalAlignment="Top" HorizontalAlignment="Left"
Width="150" Height="25"/>
<!--Label attached on top of ComboBoxB-->
<Label x:Name="LabelB" Content="LabelB"
Grid.Row="0" Grid.Column="1" VerticalAlignment="Bottom"/>
</Grid>
</Grid>
As the title of the post, I want to make a GridView which can wrap all of it's contents inside, it means if I have 3 items, each of them has 50px of height, so how to make a GridView contains these item that has 50*3=150px of height.
How to do that, please help me!
P/s: I want to do it by configuring XAML code, not in C# code, thanks!
I found out the answer! Just set the height of the GridView to Auto by make it inside a Grid row.
<Grid Grid.Row="0"
Margin="12,24">
<Grid.RowDefinitions>
<RowDefinition Height="64" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid Opacity=".8"
Background="White"
Height="64">
<Grid Margin="8">
<TextBlock Text="Students"
VerticalAlignment="Center"
FontSize="24" />
</Grid>
<Grid Height="2"
VerticalAlignment="Bottom"
Background="#B0BEC5" />
</Grid>
<GridView Background="White"
Name="grvMatchGA"
Grid.Row="1"
ItemTemplate="{ThemeResource groupItemTemplate}"
Opacity=".8"
ScrollViewer.HorizontalScrollBarVisibility="Disabled"
ScrollViewer.VerticalScrollBarVisibility="Disabled"
VerticalAlignment="Stretch">
</GridView>
</Grid>
If you don't provide height for gridview but it's children, it automatically takes the height equivalent to sum of children's height.
For example, you can do something like this-
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="50"/>
<RowDefinition Height="50"/>
<RowDefinition Height="50"/>
</Grid.RowDefinitions>
<TextBox Grid.Row="0"/>
<TextBox Grid.Row="1"/>
<Button Grid.Row="2"/>
</Grid>
below is my xaml structure:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<TextBlock Text = "{Binding Test}" />
<GroupBox Header = "Test" Grid.Row="1">
<TextBlock Text = "{Binding Description}" />
</GroupBox>
</Grid>
My Description is very long, but there's no vertical scrollviewer display in my groupbox. I don't want to set a specific height to the groupbox. Anyone can help?
You can set TextWrapping="Wrap" and wrap it in ScrollViewer with HorizontalScrollBarVisibility="Disabled":
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<TextBlock Text="{Binding Test}" />
<GroupBox Header="Test" Grid.Row="1">
<ScrollViewer HorizontalScrollBarVisibility="Disabled" VerticalScrollBarVisibility="Auto">
<TextBlock TextWrapping="Wrap" Text="{Binding Description}" />
</ScrollViewer>
</GroupBox>
</Grid>
I have the following XAML source to demonstrate what I am working on.
I want, when resizing the group vertically, is to have the first groupbox expand, up to its max height, then, when that is reached, expand the third groupbox.The third groupbox has a min height property, as well.

</GroupBox>
<GroupBox Header="Thing3" Background="Pink" Grid.Row="2" Grid.Column="0">
<TextBox Text="Stuff3" />
</GroupBox>
</Grid>
</UserControl>
Normally, when I just want a single control expanded to fill the available space, I use a DockPanel. I've built this example with all kinds of assortments of grids and dockpanels, however, I have been unable to resolve how to make it work. Any idea on how to make it happen?
Thanks
You have to set the MaxHeight on your first RowDefinition, not on the GroupBox. The row will grow up to that height and then all excess space will be occupied by the third row. You can also add a MinHeight to the third row.
<Grid x:Name="LayoutRoot" Background="White" Margin="0,0,0,0">
<Grid.RowDefinitions>
<RowDefinition MaxHeight="350" />
<RowDefinition Height="Auto"/>
<RowDefinition MinHeight="150" />
</Grid.RowDefinitions>
<GroupBox Header="Thing1" Background="LightGreen" Grid.Row="0" Grid.Column="0">
<Button Content="Stuff1" />
</GroupBox>
<GroupBox Header="Thing2" Background="LightBlue" Grid.Row="1" Grid.Column="0">
<TextBox Text="Stuff2" Height="60" />
</GroupBox>
<GroupBox Header="Thing3" Background="Pink" Grid.Row="2" Grid.Column="0">
<TextBox Text="Stuff3" />
</GroupBox>
</Grid>
