Grid Splitter problem in WPF - wpf

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"
TextWrapping="Wrap">Left Hand Side</TextBlock>
</StackPanel>
<GridSplitter HorizontalAlignment="Right" ResizeDirection="Columns" Width="5" />
<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>

Textbox doesn't fit to its content size in an expander

I have a Xaml view where I'm trying to display Textbox inside a grid which is inside an Exander.
<Expander DataContext="{Binding DiagnosticCategories[0].DiagnosticResults[0]}" <!-- For the test -->
Background="Transparent"
Foreground="{StaticResource ActiveForegroundBrush}"
IsExpanded="False">
<Grid Margin="10">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" SharedSizeGroup="A" />
<ColumnDefinition Width="*" SharedSizeGroup="A" />
<ColumnDefinition Width="auto" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="auto" />
<RowDefinition Height="auto" />
<RowDefinition Height="auto" />
</Grid.RowDefinitions>
<StackPanel
Grid.Row="1"
Grid.Column="0"
VerticalAlignment="Top">
<TextBox
Margin="10"
Background="Transparent"
BorderThickness="0"
FontSize="13"
FontWeight="Light"
Foreground="{StaticResource ActiveForegroundBrush}"
IsReadOnly="True"
Opacity="0.8"
ScrollViewer.HorizontalScrollBarVisibility="Disabled"
SelectionBrush="Black"
Text="{Binding FormatedParameters, Mode=OneWay}"
TextWrapping="Wrap" />
</StackPanel>
[...]
</Grid>
</Expander>
However, there is a problem with the Textbox which has a anormal height even if my text is just "aa"...
First, I thought that the problem was with the Grid.Row and the Textbox only fit it so I tried to add a StackPanel which doesn't fit the Grid.Row but it doesn't work. It seems that the problem is in the textbox.
With a TextBlock, I don't have this problem but I need the Textbox to display my text.
You can try RichTextBox.
When I want to use TextBox, I have the same problem under a certain height. I solved the problem by using RichTextBox instead of TextBox.
<Expander DataContext="{Binding DiagnosticCategories[0].DiagnosticResults[0]}" <!-- For the test -->
Background="Transparent"
Foreground="{StaticResource ActiveForegroundBrush}"
IsExpanded="False">
<Grid Margin="10">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" SharedSizeGroup="A" />
<ColumnDefinition Width="*" SharedSizeGroup="A" />
<ColumnDefinition Width="auto" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="auto" />
<RowDefinition Height="auto" />
<RowDefinition Height="auto" />
</Grid.RowDefinitions>
<StackPanel
Grid.Row="1"
Grid.Column="0"
VerticalAlignment="Top">
<RichTextBox
Margin="10"
Background="Transparent"
BorderThickness="0"
FontSize="13"
FontWeight="Light"
Foreground="{StaticResource ActiveForegroundBrush}"
IsReadOnly="True"
Opacity="0.8"
ScrollViewer.HorizontalScrollBarVisibility="Disabled"
SelectionBrush="Black"
Text="{Binding FormatedParameters, Mode=OneWay}"
TextWrapping="Wrap" />
</StackPanel>
[...]
</Grid>
</Expander>
As others mentioned, I'm a little unsure what you are trying to achieve. I added a couple of horizontal and vertical layouts to your example:
<Expander DataContext="{Binding DiagnosticCategories[0].DiagnosticResults[0]}"
Background="Yellow" HorizontalAlignment="Center" VerticalAlignment="Center" MinWidth="200"
IsExpanded="False">
<Grid Margin="10" Background="Blue">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" SharedSizeGroup="A" />
<ColumnDefinition Width="*" SharedSizeGroup="A" />
<ColumnDefinition Width="auto" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="auto" />
<RowDefinition Height="auto" />
<RowDefinition Height="auto" />
</Grid.RowDefinitions>
<StackPanel
Grid.Row="1"
Grid.Column="0"
VerticalAlignment="Top">
<TextBox
Margin="10"
Background="Orange"
BorderThickness="0"
FontSize="13"
FontWeight="Light"
IsReadOnly="True"
Opacity="0.8"
ScrollViewer.HorizontalScrollBarVisibility="Disabled"
SelectionBrush="Black"
Text="Test Text"
TextWrapping="Wrap"
/>
</StackPanel>
</Grid>
</Expander>

Can we use multi xaml layout on a window?

I think that we can use multi layout on a windows with XAML.
So I try to create a window like this:
I want to create an ListView in left and it can be resized. The Grid and Textbox at the left side will be fit to the right grid.
I have tried to use other layouts, StackPanel, DockPanel.
How can I create a resizable grid

</Grid>
</Grid>
<StatusBar Grid.Row="3" Height="25" HorizontalAlignment="Stretch">
<TextBlock Name="abc">abc</TextBlock>
</StatusBar>
</Grid>
But when I resize the left side.
try this
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="5" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock FontSize="55" HorizontalAlignment="Center" VerticalAlignment="Center" TextWrapping="Wrap">Left side</TextBlock>
<GridSplitter Grid.Column="1" Width="5" HorizontalAlignment="Stretch" />
<TextBlock Grid.Column="2" FontSize="55" HorizontalAlignment="Center" VerticalAlignment="Center" TextWrapping="Wrap">Right side</TextBlock>
</Grid>
As you can see, I've simply created a Grid with two equally wide columns, with a 5 pixel column in the middle.

WPF - GridSplitter not working between two grids

I have some issues with getting the grid splitter to work properly.
I have placed the GridSplitter between two grids but the problem is that the grid splitter attaches to left grid which is the only one I can move with the splitter. If I move the left grid towards the right grid, the right grid will get smaller but if I move it away from the right grid it will not expand more than its initial size.
How can I place the GridSplitter in such a way that it allows me to adjust the width of the right grid and then reducing the width of the left grid if it is dragged that way.
I did add a SharedSizeGroup to one of the child grids of the right grid but I'm not sure if that is relevant to my problem, removing it didn't solve anything.
I have also tried to play around with the ResizeBehavor of the GridSplitter also without luck.
I hope it makes sense.

I changed the Grid "logic" a bit. As I understand you correct you want the GridSplitter for the middle part. Thats why I put the top and bottom part in extra rows to keep them away from the GridSplitter. I had to remove the HorizontalAlignment="Right" from your right Grid, too. Otherwise it would have not changed it's size.
Just to be sure the GridSplitter is working I removed the WebBrowser and added Background colors to the left and right Grid. You can replace that. Thought maybe it would be helpfull for you to see if it's working like expected.
/edit added width relation
<Grid Grid.Row="1">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="2*" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="1*" />
</Grid.ColumnDefinitions>
<!-- The "Left" Grid -->
This means when you start the application the first column will take twice the size then the third.
This should be a decent showcase, it's exactly the same for columns, just sideways.
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="300"/> //sets the height of the first row
<RowDefinition Height="*"/> //* sets the remainder of the height, doesn't work like auto!
</Grid.RowDefinitions>
<Grid Grid.Row="0"

Double Grid Splitter

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.

But i suggest you to remove scrollviewer and canvas control from your layout. because both are usefulness. If i guess right you need scrolling in your ListBox control and The Listbox control has it's own scroll implementation. You should remove height property from listbox if you define height of grid's 1st row like
<RowDefination Height="*"/>
or
<RowDefination Height="400"/>
<ListBox.ItemTemplate>
<DataTemplate>
<Grid x:Name="content" Height="70" Width="480">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"></RowDefinition>
<RowDefinition Height="Auto"></RowDefinition>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"></ColumnDefinition>
<ColumnDefinition Width="*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Image x:Name="img" Source="{Binding Path=img}" Grid.Row="0" Grid.Column="0" Margin="20,0,0,0" Height="70" Width="150"></Image>
<TextBlock x:Name="countryname" Text="{Binding Path=short_name}" Grid.Row="0" Grid.Column="1" VerticalAlignment="Center" Height="70" Padding="0,15,0,0" Margin="15,0,0,0" FontSize="32" FontFamily="The Times of Roman"></TextBlock>
<Border x:Name="brd1" BorderBrush="White" BorderThickness="0,2,0,2" Grid.ColumnSpan="2" ></Border>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Don't use Auto for ScrollViewer. Auto stretches the ScrollViewer same size as canvas. You need to set fixed height so content can be scrolled within it.
The list box control has it's own scroll implementation. Unless you are going to have other elements along side the list box, I would remove the scroll viewer and canvas elements.
