My DataGrid is not taking the whole space when I maximize the window in my WPF application. This is how I created the layout:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<Grid Grid.Row="0" Grid.Column="0" Width="265">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="200" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<Label Grid.Row="0" Grid.Column="0" Content="Date From:" />
<Label Grid.Row="1" Grid.Column="0" Content="Date To:" />
<DatePicker Grid.Column="1" Grid.Row="0" Margin="3" x:Name="DateFrom" />
<DatePicker Grid.Column="1" Grid.Row="1" Margin="3" x:Name="DateTo" />
<Button Grid.Column="1" Grid.Row="2" HorizontalAlignment="Right"
MinWidth="80" Margin="3" Content="Send" Click="PopulateGrid" x:Name="BtnPopulateGrid"/>
</Grid>
<StackPanel Grid.Row="0" Grid.Column="1">
<DataGrid Width="Auto" x:Name="Grid" Height="553"
Padding="10 0 0 0" VerticalScrollBarVisibility="Visible" Margin="10,0,-707,0" />
</StackPanel>
</Grid>
and this is how it looks like on regular size:
and this is how it looks like when window is max:
What can I try next? I am new to WPF.
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid Grid.Row="0" Grid.Column="0">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="200" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<Label Grid.Row="0" Grid.Column="0" Content="Date From:" />
<Label Grid.Row="1" Grid.Column="0" Content="Date To:" />
<DatePicker Grid.Column="1" Grid.Row="0" Margin="3" x:Name="DateFrom" />
<DatePicker Grid.Column="1" Grid.Row="1" Margin="3" x:Name="DateTo" />
<Button Grid.Column="1" Grid.Row="2" HorizontalAlignment="Right" MinWidth="80" Margin="3" Content="Send" Click="PopulateGrid" x:Name="BtnPopulateGrid"/>
</Grid>
<Grid Grid.Row="0" Grid.Column="1">
<DataGrid x:Name="Grid" Padding="10 0 0 0" VerticalScrollBarVisibility="Visible" />
</Grid>
</Grid>
Firstly if you wanna make your datagrid fill a container automatically, you need to use Grid, not StackPanel also your datagrid sizes need to be set auto.
Edit:
As #Erjon said : You don't have to use a container when you have a single DataGrid.But if you have more components with your DataGrid, Grid will be a better container choice instead of StackPanel.
Your main GridDefination sizes were set as Auto, that was wrong.You need to work with "*" if you want a resposive design.Auto means that "Set this control's size with its children".
Try adding in the datagrid ColumnWidth="*"
It will expand all columns to avaiable space and the datagrid will fill it's parent
The second ColumnDefinition of the first grid should be <ColumnDefinition Width="*" />
And as #Zacos said in my answers comment you have to remove Width
I have a DockPanel, which contains some controls including a ScrollViewer.
What I WANT to happen, is for the ScrollViewer to allow the grid to be scrolled, without pushing other controls off the bottom of the form.
Instead, the ScrollViewer expands to the height of the window, rather than the top of the Button, pushing the Button off for the bottom of the form. Why is this? How do I fix it?

I want the menu bar at the top of the screen, the button at the bottom of the screen, and the grid with the ScrollViewer in the middle. What am I doing wrong?
The problem is that the ScrollViewer doesn't know how much height it should get. ScrollViewer is a control that tries to get as much size as its children need. DockPanel also gives as much size as the ScrollViewer need and therefore your problem. You can fix height of the ScrollViewer with pixels (i.e. Height=100) To make it a fixed height. I don't know your use case so this might be useful if you are showing an image carousel for example.
In more general layout advice I might say that you'd better use a grid instead of a DockPanel:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="auto" />
<RowDefinition Height="auto" />
<RowDefinition Height="auto" />
<!-- Next one is for middle part of the page -->
<RowDefinition Height="*" />
<RowDefinition Height="auto" />
</Grid.RowDefinitions>
<!-- your controls here -->
</Grid>
I found that I could have a dynamic height with the DockPanel if I stuck the whole thing in a Grid. This appears to work, as I can now have a dynamic height for the ScrollViewer.
<Window x:Class="Class1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:Class1"
mc:Ignorable="d"
Title="MainWindow" Height="800" Width="600"
WindowStartupLocation="CenterScreen">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<DockPanel Grid.Column="0" Grid.Row="0" LastChildFill="False">
Everything is then as normal EXCEPT that I move my button outside of the DockPanel and into the Grid's second row:
</DockPanel>
<Button Grid.Column="0" Grid.Row="1" Name="btnButton1" DockPanel.Dock="Bottom" Click="btnButton1_Click" >ButtonText</Button>
</Grid>
The rows with a Height of "Auto" will size to fit their content. The rows with a Height of asterisk (*) will size to fill the remaining space after the size of the Autos has been calculated. Thus everything sizes up correctly and nicely.
Alternatively, at this point I can do-away with the DockPanel entirely and have the Menu, ToolBarTray, ScrollViewer, and Button in their own separate grid rows, like Emad suggests in their answer (although I'm not sure what the extra row is for in their example).
<Grid.ColumnDefinitions>
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
I ultimately decided to go for that approach, so I'll mark it as the answer, but I'm putting this all here for the full explanation, for completeness (in case people do happen to want to keep their DockPanel).
I have an application (implemenented in WPF, XAML) which has 6 rows and 6 columns. At the position Grid.Row="1" Grid.RowSpan="4" Grid.Column="0" Grid.ColumnSpan="5" , I'm using a TabControl for Dashboard, Housekeeping, and Science. In every TabControl, I'm using a ListBox on the left side to choose individual data. The rest (w/o the ListBox) of the field/grid (which should have a size of 4 rows and 4 columns) is available for charts.
Problem
The charts which are visible in the screenshot below should be stretched over 4 rows down to the bottom edge of the application according to the XAML code. The TabControl is not 4 rows as visible because of the white boarder I have attached.
How can I change my grid-concept that it works as described above? Is a grid in the grid, resp. in the TabControl necessary at all?

Replace your StackPanels with Grids. StackPanels size to their child elements, whereas Grids size to their parent.

I have an existing WPF MainWindow.xaml with a defined grid. In one of these grid-fields is a button which opens the following "ChildWindow":

If I include the code within the grid area of the MainWindow.xaml as seen above, the window opens in Grid.Row="0" Grid.Column="0" by default instead of being a independent new window in the center of the screen exactly like the demo project. I have both projects side by side but cannot see the difference. Can anyone help me?
Thank you!
You defined rows and columns in your root grid, so you should say this to the child window with Grid.ColumnSpan and Grid.RowSpan:
<simpleChildWindow:ChildWindow x:Name="ChartControllings"
Grid.ColumnSpan="6"
Grid.RowSpan="6"
CloseByEscape="False"
ChildWindowWidth="400"
ChildWindowHeight="300"
HorizontalContentAlignment="Stretch"
VerticalContentAlignment="Stretch"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Padding="1"
ChildWindowImage="Error"
Title="Chart Controllings">
or you insert another Grid and do it like so:
<Grid>
<Grid>
<!-- Definition of Rows and Columns -->
<Grid.RowDefinitions>
<RowDefinition Height="50" />
<RowDefinition Height="*" />
<RowDefinition Height="*" />
<RowDefinition Height="*" />
<RowDefinition Height="*" />
<RowDefinition Height="250" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="150"/>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />

<!-- Here are some other, uninteresing code lines -->

Hope that helps!
So for example... in the following user control I have a grid with two rows. I want the bottom row to be the height of it's contents and the top row to be the height of the rest of the grid. I can set a absolute height as in the example, but that isn't particularly flexible. Say someone changes a font sizing the text could get clipped. Is there any built in way to achieve this?
<UserControl x:Class="Tournament.View.TeamCreator"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" >
<Grid x:Name="LayoutRoot" Background="White" ShowGridLines="True">
<Grid.RowDefinitions>
<RowDefinition Height="1*" />
<RowDefinition Height="20" />
</Grid.RowDefinitions>
<Grid Grid.Row="1" >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1*" />
<ColumnDefinition Width="1*" />
<ColumnDefinition Width="1*" />
<ColumnDefinition Width="1*" />
<ColumnDefinition Width="1*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="1*" />
</Grid.RowDefinitions>
<TextBlock Grid.Column="0" Grid.Row="0" Text="TEAM NAME" />
<TextBox Grid.Column="1" Grid.Row="0" />
<TextBlock Grid.Column="2" Grid.Row="0" Text="MANAGER NAME" />
<TextBox Grid.Column="3" Grid.Row="0" />
<Button Grid.Column="4" Grid.Row="0" />
</Grid>
</Grid>
</UserControl>
In WPF this is as simple as:
<Grid.RowDefinitions>
<RowDefinition Height="1*" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
I suspect the same works in Silverlight?
