Different Behaviour of Grid.RowDefinition at runtime and at design time

suppose I have a grid like below:
<Grid>
<Grid.Resources>
<converters:MultiplyHeightByThreeConverter x:Key="multiplyHeightByThreeConverter" />
</Grid.Resources>
<Grid.RowDefinitions>
<RowDefinition Height="{Binding ElementName=rowPinCode, Path=ActualHeight, Converter={StaticResource multiplyHeightByThreeConverter}}"/>
<RowDefinition x:Name="rowPinCode" Height="Auto" />
.....
.....
</Grid.RowDefinitions>
.....
.....
</Grid>
Here is my Converter Code :
public class MultiplyHeightByThreeConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return (((double)value) * 3);
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
throw new NotImplementedException();
}
}
At Design time I get the expected Output :
But at Runtime I don't get that row :
I have also found the reason for that :
I kept a breakpoint on converter's Convert Method's opening bracket and found that value of value parameter is 0.00
How do I solve the problem?
I also tried to use Height instead of ActualHeight but then I get error because it cannot convert Auto to Double

Update 2:
After your suggestions :
At Design Time:
At Runtime :

You don't need converter. In case you want first row to be thrice of second row, you can give relative width using 3*.
<Grid.RowDefinitions>
<RowDefinition Height="3*"/>
<RowDefinition x:Name="rowPinCode" Width="Auto" Height="*" />
.....
</Grid.RowDefinitions>
UPDATE
Using row definitions like mentioned above works completely fine at my end. Definition's declaration:
<Grid.RowDefinitions>
<RowDefinition Height="5" />
<RowDefinition Height="3*" />
<RowDefinition Height="10" />
<RowDefinition x:Name="rowPinCode" Height="*"/>
<RowDefinition Height="10" />
<RowDefinition Height="Auto" />
<RowDefinition Height="10" />
<RowDefinition Height="Auto" />
<RowDefinition Height="5" />
</Grid.RowDefinitions>

How to put two different textboxes into same level?

Right xaml code looks this way:
mc:Ignorable="d" d:DesignWidth="363" Height="628">
<Grid Style="{StaticResource ContentRoot}">
<ScrollViewer Margin="0,-105,-9,0">
<StackPanel MinWidth="200" HorizontalAlignment="Left" Width="474" Height="459">
</InlineUIContainer>
<Run Language="ru-ru"/>
<LineBreak/>
<Run Language="ru-ru" Text="Num1"/>
<LineBreak/>
<InlineUIContainer>
<TextBox d:DesignUseLayoutRounding="True"
Width="160"
UseLayoutRounding="True"
Text="Enter num"
TextWrapping="Wrap"
x:Name="TxtBlock_numRequest"
InputMethod.IsInputMethodEnabled="False"
Height="23"
AutoWordSelection="True"/>
</InlineUIContainer>
<LineBreak/>
<Run Language="ru-ru"/>
<LineBreak/>
<Run Language="ru-ru" Text="ID"/>
<Run Text=" "/>
<LineBreak/>
<InlineUIContainer>
<TextBox Width="160"
Text="Enter num"
TextWrapping="Wrap"
x:Name="TxtBlock_IDWork"
Height="23"/>
As you can there are two textboxes, which located one under other one, and I need to put them into same level, I tried it to via constructor, it simply don't do it in my particular case. To clearify I have added pictures.
And don't be afraid foreign inscriptiones, its doesn't matter.
I just don't know how to fix this, and I think it' related with StackPanel. Any ideas ?
UPD: All xaml code here http://snipt.org/Btff4/Default#expand
UPD: May be it possible to put one more stack panel rigt to existing one?

You are probably looking for Orientation attribute:
<StackPanel MinWidth="200" HorizontalAlignment="Left" Width="474" Height="459" Orientation="Horizontal">
Update
Adding a very basic example to illustrate how StackPanel works:
<Window x:Class="WpfTestBench.Stackpanel"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" SizeToContent="WidthAndHeight">
<StackPanel Orientation="Horizontal" Margin="10">
<TextBox Text="First textbox" Height="20" Margin="5, 0" />
<TextBox Text="Second textbox" Height="20" />
</StackPanel>
</Window>
Execution result:
Update
Adding XAML which allows to achieve desired layout:
<Window x:Class="WpfTestBench.Stackpanel"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Sample layout" SizeToContent="Height" Width="400">
<Grid Margin="10">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="50" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition />
</Grid.RowDefinitions>
<Label Grid.ColumnSpan="3" Grid.Row="0" Content="Задайте параметры заявок" FontWeight="Bold" FontSize="16" />
<Grid Grid.Column="0" Grid.Row="1">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="10" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<TextBlock Grid.Row="0" Text="номер заявки" />
<TextBox Grid.Row="1" Text="Введите число" />
<TextBlock Grid.Row="3" Text="приоритет заявки" />
<ComboBox Grid.Row="4" SelectedIndex="0">
<ComboBoxItem Content="Высокий" />
<ComboBoxItem Content="Средний" />
<ComboBoxItem Content="Низкий" />
</ComboBox>
</Grid>
<Grid Grid.Column="2" Grid.Row="1">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="10" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<TextBlock Grid.Row="0" Text="идентификатор вида работы" />
<TextBox Grid.Row="1" Text="Введите число" />
<TextBlock Grid.Row="3" Text="номер траектории" />
<TextBox Grid.Row="4" Text="Введите число" />
</Grid>
</Grid>
</Window>
Execution result:

You can use a StackPanel with Orientation="Horizontal", as a container. Something like:
<StackPanel Orientation="Horizontal">
<StackPanel>
<TextBlock>Label</TextBlock>
<TextBox Width="150"/>
</StackPanel>
<StackPanel>
<TextBlock>Label 2</TextBlock>
<TextBox Width="150"/>
</StackPanel>
</StackPanel>

I prefer Grid defintion than StakPanel. You can easily design your application with that method, just cut each area in many smaller area. Use Auto and * to define proportion.
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid Grid.Row="0">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Label Content="Label" Grid.Row="0" Grid.Column="0" HorizontalAlignment="Center" />
<Label Content="Label" Grid.Row="0" Grid.Column="1" HorizontalAlignment="Center" />
<TextBox Text="Text here !" Grid.Row="1" Grid.Column="0" />
<TextBox Text="Text here !" Grid.Row="1" Grid.Column="1" />
</Grid>
<Grid Grid.Row="1">
<Label Content="I need this kind of location" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Grid>
</Grid>

Grid should do what you need:
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition></ColumnDefinition>
<ColumnDefinition></ColumnDefinition>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="40"></RowDefinition>
<RowDefinition Height="40"></RowDefinition>
</Grid.RowDefinitions>
<TextBlock Name="lblTextBlock1" Text="Text Block" VerticalAlignment="Center" HorizontalAlignment="Center" />
<TextBox Text="TextBlock1" Grid.Row="1" Margin="5,0,0,0" MaxHeight="20" MinWidth="100" MaxLength="4" MaxWidth="40"></TextBox>
<TextBlock Grid.Column="1" Name="lblTextBlock2" Text="Text Block" VerticalAlignment="Center" HorizontalAlignment="Center" />
<TextBox Grid.Column="1" Text="TextBlock2" Grid.Row="1" Margin="5,0,0,0" MaxHeight="20" MinWidth="100" MaxLength="4" MaxWidth="40"></TextBox>

And i noticed that when i press a item in the list so the user not have any thing to know which item he pressed, something like focus the item when he press it.
In iPhone the the selected row get blue and when release the blue selection is disappear,there is some equivalent to this in windows phone too?

Use TiltEffect from Silverlight Toolkit for Windows Phone, details are here http://www.geekchamp.com/articles/silverlight-for-wp7-toolkit-tilteffect-in-depth. Also to make an effect more expressive use Button as a container for your ItemTemplate with EmptyButtonStyle http://www.jeff.wilcox.name/2011/10/hyperlinkbutton-empty-style-for-phone/.

DockPanel Resizing and TextBox linebreak

I have a DockPanel with two Grids (DockPanel.Dock="Right/Left"). In the left i have a TreeView and in the right i have some TextBoxes. If i resize my window the panels resize proportinal.
My problem is, if i write long text in a TextBox the TextBox enlarge and hide my left DockPanel instead of a break the text.
I have set minwidth of the left DockPanel to '300' and set TextWrapping in the TextBoxes to 'wrap' but nothing helps.

<Button Grid.Column="1" Width="26" Click="ButtonAddItem_Click">
</Grid>
<ListView />
</DockPanel>
</Grid>
</DockPanel>
</Grid>
</DockPanel>
</Grid>

That's pretty much why Dockpanels are useless :-)
I suggest using Grid..
