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.

<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 tried to implement a GridSplitter to my WPF Window - like shown here http://www.wpf-tutorial.com/panels/gridsplitter/
Worked just well. But I wanna do a double grid splitter. So the window should be splitted in a left and a right part. And the right part should be splitted in a top and a button part.
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="5" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<Grid></Grid>
<GridSplitter Grid.Column="1" Width="5" HorizontalAlignment="Stretch" />
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="5" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<TextBlock FontSize="55" HorizontalAlignment="Center" VerticalAlignment="Center" TextWrapping="Wrap">One</TextBlock>
<GridSplitter Grid.Row="1" Height="5" HorizontalAlignment="Stretch" />
<TextBlock Grid.Row="2" FontSize="55" HorizontalAlignment="Center" VerticalAlignment="Center" TextWrapping="Wrap">Two</TextBlock>
</Grid>
</Grid>
Buuut it alawys splits up the left part in two pieces. I tried like everything setting the Grid.Row and Grid.column for everything explicit - but nothing. What am I missing?
To achieve what you would like:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="5" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock FontSize="55" HorizontalAlignment="Center" VerticalAlignment="Center" TextWrapping="Wrap">Left</TextBlock>
<GridSplitter Grid.Column="1" Width="5" HorizontalAlignment="Stretch" />
<Grid Grid.Column="2">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="5" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<TextBlock FontSize="55" HorizontalAlignment="Center" VerticalAlignment="Center" TextWrapping="Wrap">Top</TextBlock>
<GridSplitter Grid.Row="1" Height="5" HorizontalAlignment="Stretch" />
<TextBlock Grid.Row="2" FontSize="55" HorizontalAlignment="Center" VerticalAlignment="Center" TextWrapping="Wrap">Bottom</TextBlock>
</Grid>
</Grid>
You didn't set Grid.Column="2" on the the second Grid you intended to be on the right.
I also changed the Width and Height properties to * so the horizontal and vertical GridSplitters will sit in the center.
I have a textbox and listview inside a grid in WPF app. What I want is, when the text overflows inside the textbox, the listview height should reduce accordingly to accommodate the textbox. Just like what happens in WhatsApp messenger when we type it in its textbox.
Here's my code:
<Grid MouseDown="ShowTextBox" Height="566" VerticalAlignment="Top" Margin="10,0,40,0" Background="White" Grid.Row="1">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<ListView MaxHeight="544" VerticalAlignment="Top" ScrollViewer.VerticalScrollBarVisibility="Auto" ScrollViewer.HorizontalScrollBarVisibility="Disabled" S Grid.Row="0" Margin="20,0,0,0" x:Name="sessionNotesList" />
<TextBox Grid.Row="1" Height="Auto" MinHeight="100" MaxHeight="554" VerticalAlignment="Top" Margin="20,0,30,12" SpellCheck.IsEnabled="True" TextWrapping="Wrap" x:Name="sessionNoteContent" KeyUp="SaveNote" LostFocus="sessionNoteContent_LostFocus" />
</Grid>
Have you tried reversing the Grid.RowDefinitions so that the ListView takes all of the remaining space instead?:
<Grid MouseDown="ShowTextBox" Height="566" VerticalAlignment="Top" Margin="10,0,40,0" Background="White" Grid.Row="1">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<ListView MaxHeight="544" VerticalAlignment="Top" ScrollViewer.VerticalScrollBarVisibility="Auto" ScrollViewer.HorizontalScrollBarVisibility="Disabled" S Grid.Row="0" Margin="20,0,0,0" x:Name="sessionNotesList" />
<TextBox Grid.Row="1" Height="Auto" MinHeight="100" MaxHeight="554" VerticalAlignment="Top" Margin="20,0,30,12" SpellCheck.IsEnabled="True" TextWrapping="Wrap" x:Name="sessionNoteContent" KeyUp="SaveNote" LostFocus="sessionNoteContent_LostFocus" />
</Grid>
Like others I have a DataGrid that is not showing scrollbars. What I think is unique to my situation is that I do not see a StackPanel anywhere in the visual or logical tree. I am using WPF Inspector to view the trees. I have tried various suggestions to set the height and width of the containing Grid columns and rows with no success. I'm certain there is something I'm missing that is allowing the content to extend beyond the visible area but I cannot tell what it is yet. Any help would be appreciated. This application is a WPF Prism with MEF app and the DataGrid is within a UserControl which is in a Prism region.

You have the DataGrid in a Grid row where the RowDefinition Height is auto so the grid will be measured with an infinite height and be arranged to its DesiredSize.Height and never show scrollbars. Seems like the grid should be in row 1 or make the height of row 2 to be * instead of auto.
I want a layout like VS 2008. In which I want two columns and second columns is again split into two.
I done that in the xaml mentioned below, but the GridSplitter is not visible vertically ( which split two columns).
I want both the GridSplitters to be resizable. One GridSplitter resizes the Left Hand Pane and Right Hand Pane and another GridSplitter resizes the subgrid's top pane and right pane..
The Second GridSplitter is working through this XAML but I am not able to produce XAML code that Splits the Right hand Pane and Left hand pane..
Pleas Help!!

Change your vertical Splitter to
<GridSplitter Grid.Column="0" Width="5" ResizeDirection="Auto"
Grid.RowSpan="1"
HorizontalAlignment="Right"
VerticalAlignment="Stretch"/>
This will be much better way to use GridSplitter
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="5"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<StackPanel Background="Aqua" Grid.Column="0" >
<TextBlock FontSize="35" Foreground="#58290A"
TextWrapping="Wrap">Left Hand Side</TextBlock>
</StackPanel>
<GridSplitter Grid.Column="1" HorizontalAlignment="Stretch"/>
<Grid Grid.Column="2">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="5" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<ListBox Grid.Row="0" Background="Red">
<ListBoxItem>Hello</ListBoxItem>
<ListBoxItem>World</ListBoxItem>
</ListBox>
<GridSplitter Grid.Row="1" Background="Gray" HorizontalAlignment="Stretch"/>
<ListBox Grid.Row="2" Background="Violet">
<ListBoxItem>Hello</ListBoxItem>
<ListBoxItem>World</ListBoxItem>
</ListBox>
</Grid>
</Grid>
The GridSplitters should probably be on their own row/column in the grid, not sharing a cell with the other controls.
Your gridsplitter is behind the other controls that's why you can't see it. You can either move it to the bottom in your XAML file (so it is added last) or use the Panel.ZIndex attached property. Additionally you have to set the width for the splitter correctly correctly:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<StackPanel Background="Aqua" Grid.Column="0" >
<TextBlock FontSize="35" Foreground="#58290A"
TextWrapping="Wrap">Left Hand Side</TextBlock>
</StackPanel>
<Grid Grid.Column="1">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<ListBox Grid.Row="0" Background="Red">
<ListBoxItem>Hello</ListBoxItem>
<ListBoxItem>World</ListBoxItem>
</ListBox>
<GridSplitter Grid.Row="1" Height="5" Background="Gray"
VerticalAlignment="Top" HorizontalAlignment="Stretch" />
<ListBox Grid.Row="1" Background="Violet" Margin="0,5,0,0">
<ListBoxItem>Hello</ListBoxItem>
<ListBoxItem>World</ListBoxItem>
</ListBox>
</Grid>
<GridSplitter Grid.Column="0" ResizeDirection="Columns"
Grid.RowSpan="1" Width="5"
HorizontalAlignment="Right"/>
</Grid>
I have acheived the functionality, the XAML is mentioned below:
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<StackPanel Background="Aqua" Grid.Column="0" >
<TextBlock FontSize="35" Foreground="#58290A"
