How to make grid splitter to adjust size between rows 0 and 3?


How about this
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<TextBox Grid.Row="0" Background="Blue"
VerticalAlignment="Stretch" HorizontalAlignment="Stretch" />
<GridSplitter Grid.Row="1" Height="4" Background="Red"
ResizeBehavior="PreviousAndNext" ResizeDirection="Rows"

Shared grid splitter

I have a grid that contains one ItemsControl with another grid. I would like to align the two splitters in the two grids. I have implement Grid.SharedSizeScope but this option shared only the column of the grid is located. Do you have any suggestions?
This is my xaml code.
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" SharedSizeGroup="Col1"/>
<ColumnDefinition Width="5" SharedSizeGroup="Col2"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="{StaticResource GridRowHeight}"/>
<RowDefinition Height="{StaticResource GridRowHeight}"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<GridSplitter Grid.Column="1" Grid.RowSpan="2" HorizontalAlignment="Left" Width="5" VerticalContentAlignment="Stretch" IsTabStop="False"/>
<TextBlock Name="ID" Grid.Row="0" Grid.Column="0" Text="ID"/>
<TextBox Name="TxtID" Grid.Row="0" Grid.Column="2" TabIndex="0" Text={Binding ID}/>
<TextBlock Name="Description" Grid.Row="1" Grid.Column="0" Text="Description"/>
<TextBox x:Name="TxtDescription" Grid.Row="1" Grid.Column="2" Grid.RowSpan="1" Text="{Binding Description, UpdateSourceTrigger=LostFocus}"/>
<ItemsControl ItemsSource="{Binding MyList}" Grid.IsSharedSizeScope="True" IsTabStop="False"
Grid.Row="3" Grid.Column="0" Grid.ColumnSpan="3">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" SharedSizeGroup="Col1"/>
<ColumnDefinition Width="5" SharedSizeGroup="Col2"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<GridSplitter Grid.Column="1" Grid.RowSpan="2147483647" Width="5" HorizontalAlignment="Left" VerticalContentAlignment="Stretch" IsTabStop="False"/>
<TextBlock Name="Type" Grid.Column="0" Grid.Row="0" Text="{Binding Type}"/>
<ComboBox Grid.Row="0" Grid.Column="2" ItemsSource="{Binding Source={StaticResource Types}}" SelectedItem="{Binding MyType}"/>
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>

ok, what if you will actually take out the itemscontrol and move it outside the grid and then put everything into dockpanel ?
<DockPanel Grid.IsSharedSizeScope="True">
<Grid DockPanel.Dock="Top">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" SharedSizeGroup="Col1"/>
<ColumnDefinition Width="5" SharedSizeGroup="Col2"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="20"/>
<RowDefinition Height="20"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<GridSplitter Grid.Column="1" Grid.RowSpan="2" HorizontalAlignment="Left" Width="5" VerticalContentAlignment="Stretch" IsTabStop="False"/>
<TextBlock Name="ID" Grid.Row="0" Grid.Column="0" Text="ID"/>
<TextBox Name="TxtID" Grid.Row="0" Grid.Column="2" TabIndex="0" Text="ID"/>
<TextBlock Name="Description" Grid.Row="1" Grid.Column="0" Text="Description"/>
<TextBox x:Name="TxtDescription" Grid.Row="1" Grid.Column="2" Grid.RowSpan="1" Text="123"/>
</Grid>
<ItemsControl IsTabStop="False"
Grid.Row="3" Grid.Column="0" Grid.ColumnSpan="3">
<ItemsControl.ItemTemplate>

C# windows 8 app scrollview

I can't seem to set up the scrollview right. I can use scrollbar scrollview or whatever, I just want the scroll function.
Code:
<ScrollViewer>
<Grid.RowDefinitions>
<RowDefinition Height="140"/>
<RowDefinition Height="65" />
<RowDefinition Height="30" />
<RowDefinition Height="65" />
<RowDefinition Height="30" />
<RowDefinition Height="65" />
<RowDefinition Height="30" />
<RowDefinition Height="65" />
<RowDefinition Height="30" />
<RowDefinition Height="65" />
<RowDefinition Height="30" />
<RowDefinition Height="65" />
<RowDefinition Height="65" />
<RowDefinition Height="30" />
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
</ScrollViewer>
Not sure what I'm doing wrong.

You can only use Grid.RowDefinitions under a grid:
<ScrollViewer>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="140"/>
<RowDefinition Height="65" />
<RowDefinition Height="30" />
<RowDefinition Height="65" />
<RowDefinition Height="30" />
<RowDefinition Height="65" />
<RowDefinition Height="30" />
<RowDefinition Height="65" />
<RowDefinition Height="30" />
<RowDefinition Height="65" />
<RowDefinition Height="30" />
<RowDefinition Height="65" />
<RowDefinition Height="65" />
<RowDefinition Height="30" />
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
</Grid>
</ScrollViewer>
I suspect that was your problem.
Simplified example:
You can use just one scroll viewer for the entire page. This scroll viewer can have a grid with several rows (or columns). Then you can add any control and assign them to a row:
<ScrollViewer>
<Grid>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<TextBlock Text="1" Grid.Row="0" FontSize="400"/>
<TextBlock Text="2" Grid.Row="1" FontSize="400"/>
<TextBlock Text="3" Grid.Row="2" FontSize="400"/>
</Grid>
</ScrollViewer>
To Not Shift the Whole Page
You can create a grid outside the scroll viewer like this:
<Grid>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<ScrollViewer Grid.Row="0" VerticalAlignment="Top">
<Grid>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<TextBlock Text="1" Grid.Row="0" FontSize="400"/>
<TextBlock Text="2" Grid.Row="1" FontSize="400"/>
<TextBlock Text="3" Grid.Row="2" FontSize="400"/>
</Grid>
</ScrollViewer>
<Grid Grid.Row="1">
<TextBlock
Text="outside of ScrollView control"
Foreground="Red" FontSize="50"
VerticalAlignment="Center"
HorizontalAlignment="Center"/>
</Grid>
</Grid>

WPF: multiuser scheduler

I realize Outlook's like scheduler. I took as the basis: http://www.codeproject.com/Articles/30881/Creating-an-Outlook-Calendar-Using-WPF-Part-2 , but my calendar should have some columns for show data by some count of users. Ofcourse, I can add some user's columns by XAML, but this is static solution and I don't know how many user's will show by my program.
How to improve this program for add dynamic count of user or may be there is some other open source WPF-control's for it?
XAML's code of Calendar style, which create 3 static column in the next:
<Style TargetType="{x:Type local:Calendar}">

Tabcontrol in WPF C#

now I'm using the tabcontrol to arrange my UI. At the first, I put my button outside my tabcontrol; however, when I put the button into the tabcontrol, it gave message, Object reference not set to an object instance. Does anyone know why I got this message ?

I've seen this before, its code that references things in your form before you create the form. Check the order of what you are calling.

Inside Windows tag i have added this code and for me its working fine...
<Grid Width="auto">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="432*" />
</Grid.RowDefinitions>
<TabControl Grid.Row="1">
<TabItem Header="Book Info" >

<ColumnDefinition Width="100" />
<ColumnDefinition Width="150" />
<ColumnDefinition Width="150" />
<ColumnDefinition Width="178*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="22*" />
</Grid.RowDefinitions>
<TextBlock Text="Book Code:" Height="25" Margin="0,15,0,45"> </TextBlock>

WPF Grid Splitter is not splitting

I have listviews which have been ordered up to down. I put grid splitters between each listview. But the grid splitters are not working. I could not find out why they aren't working.
My codes are below.
