WPF Using GridSplitter for individual Row Column in Grid

I want to have GridSplitter that resizes only one cell (actually not correct term per se for WPF Grid, let's call it individual Grid[r][c]) and cell adjacent to it to be resized.
Here what I tried:
<Grid>
<Grid.RowDefinitions>
<RowDefinition></RowDefinition>
<RowDefinition></RowDefinition>
<RowDefinition></RowDefinition>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition></ColumnDefinition>
<ColumnDefinition></ColumnDefinition>
<ColumnDefinition></ColumnDefinition>
</Grid.ColumnDefinitions>

I want it to behave in a way that individual cell in the Grid shall be resized.
At app start
While resizing via grid splitter:
After Reisize:
I wanted that Only Grid[ 0][ 0] and Grid[ 0][ 1] to be resized

You have 3 columns and 3 lines, not 3 columns inside each line,
try this:
<Grid >
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition />
<RowDefinition />
</Grid.RowDefinitions>
<Grid Grid.Row="0">
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<GridSplitter Grid.Column="0"/>
<GridSplitter Grid.Column="1"/>
<GridSplitter Grid.Column="2"/>
</Grid>
<Grid Grid.Row="1">
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
</Grid>
<Grid Grid.Row="2">
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
</Grid>
</Grid>

Have own code (for "simplicity", sorry) which addresses vertical gridsplitting. Given time, will be including an update for the horizontal, but assuming it's no more than defining distinct grid columns instead of Celso's distinct grid rows.
There's certainly some issue in applying the particular member fields of GridSizeBehaviour.
Replace CurrentAndNext with the BasedOnAlignment property in the first attached vertical gridsplitting example to find that all rows are affected- not just the the row the gridsplitter was defined on.
To bug out GridSizeBehaviour, replace CurrentAndNext with PreviousAndCurrent in there for the 0'th row definition and find that once the gridsplitter is clicked, it never returns/loses visibility, along with the rest of the controls on the form.
<Window x:Class="GridSplitterSample.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

<Button Grid.Row="2" Grid.Column="0">Button 2</Button>
<Button Grid.Row="2" Grid.Column="2">Button 3</Button>
</Grid>
Perhaps there is an API solution to this? But using Celso's idea of nested grids, it works in the following code:
<Window x:Class="GridSplitterSample.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="GridSplitterSample" Height="300" Width="300">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid Grid.Row="0">
<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.Row="0" Grid.Column="1" Width="5" HorizontalAlignment="Stretch" ResizeBehavior="CurrentAndNext" />
<TextBlock Grid.Column="2" FontSize="55" HorizontalAlignment="Center" VerticalAlignment="Center" TextWrapping="Wrap">Right side</TextBlock>
</Grid>
<Grid Grid.Row="1" >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="5" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Button Grid.Column="0" Grid.ColumnSpan="3">Button 1</Button>
</Grid>
<Grid Grid.Row="2" >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="5" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Button Grid.Column="0">Button 2</Button>
<Button Grid.Column="2">Button 3</Button>
</Grid>
</Grid>
More needs to be done with this, however, for if the user drags the gridsplitter to the edge of a form maximised to screen size, it cannot be retrieved! Looks like it was never the policy of MS to touch row/columns/cells in a grid, as they are basically user defined criteria.

Strange display behaviour of Windows Phone 8 device in different resolutions(WVGA,WXGA,&720P)

This is my XAML design
<Grid x:Name="ContentPanel2" Grid.Row="1" Background="Black" Height="440" Width="440">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Border BorderThickness="0" Grid.Row="0" Grid.Column="0" Background="White" />
<Border BorderThickness="0" Grid.Row="0" Grid.Column="1" Background="White" />
<Border BorderThickness="0" Grid.Row="0" Grid.Column="2" Background="White" />
<Border BorderThickness="0" Grid.Row="1" Grid.Column="0" Background="White" />
<Border BorderThickness="0" Grid.Row="1" Grid.Column="1" Background="White" />
<Border BorderThickness="0" Grid.Row="1" Grid.Column="2" Background="White" />
<Border BorderThickness="0" Grid.Row="2" Grid.Column="0" Background="White" />
<Border BorderThickness="0" Grid.Row="2" Grid.Column="1" Background="White" />
<Border BorderThickness="0" Grid.Row="2" Grid.Column="2" Background="White" />
</Grid>
Here are the images
wvga image
wxga image
720pimage
This appears differently in each resolutions (wvga,wxga & 720p).
Anybody knows why this behaviour happens?
How to resolve this issue?

This is a known issue (thought it had another StackOverflow question but I couldn't find it) with how the fractional pixels work out - you can see the background of the Grid showing through "gaps" between your items.
You can fix it by making the Background of the Grid White.

WPF window shows blank

Excel AddIn, c#, .net 4.0, windows 7, ribbon
my addin has a ribbon tab, several ribbon buttons,
when one ribbon is clicked, the addin will send several web service calls and a window will pop up providing data in tab, treeview, gridview etc.
data in treeview, gridview are populated from web service calls.
All worked for a particular end user until yesterday
When he clicked button, the window seems showing up, but it is kind of behind Excel and could not be focused. Also it is blank with no tab, treeview, gridview, etc.
I verified all web service calls return properly.
The user has windows 7, Excel 2010 (32 bit).
I have no idea what could cause this. Please help.
this is my WPF window. thanks

I know this is old -- but we stumbled on to this with a legacy Office add-in that we support -- where one user is apparently experiencing this same issue.
We did some digging, and stumbled across this similar SO post: Blank WPF child windows on Windows 10
It looks like there are two options:
Instruct the user to update/fix their bad video card drivers.
Put a hack into the code that will force the content to redraw at just the right instant (i.e. InvalidateVisual is not sufficient, see the linked question's answers for more information).

My problem is that I don't know HOW to use this DataTemplate inside my selector. What is the XAML I need to use? With controls like ListBox it is easy, just set ItemTemplate="{StaticResource thisTemplate}" but how do I do this in my case? Still learning XAML

Just set the DetailedTemplate property in the tag itself:
<Mobile:DevicePushpinTemplateSelector
m:MapLayer.Position="{Binding Location}"
ZoomLevel="{Binding ZoomLevel, ElementName=MainMap}"
Content="{Binding}"
DetailedTemplate="{StaticResource DetailedMapItemTemplate}">

Making a customized schedule in WPF

I'm new to vs10 and I'm trying to make a customized schedule/calender using WPF. So far I have somewhat of a visual. I'm using a grid with rectangles and separators to make the grid lines. What I'm confused on is how I can make every month. I want to be able to have two arrow buttons switching between months but I'm not sure what I can do to make the correct dates to appear where they should be. I was going to use buttons to display each date on the calender so when the user clicks on it he/she can add an event/appointment for that particular day/date. Any advice or tips is greatly appreciated.

Usually I would bind a list of Day objects to an ItemsControl whose ItemsPanel is set to a Grid with 6 rows, and 7 columns, and either have each Day track what Week and WeekDay it belongs to, or have a converter figure out those values for me. Then I could bind those values to Grid.Row and Grid.Column in my ItemsControl.ItemContainerStyle
So my Day object would look like:
public class Day : INotifyPropertyChanged
{
// Of course, these should implement the usual PropertyChange Notifications
public int WeekNo {get; set;}
public int WeekDay {get; set;}
public DateTime Date {get; set;}
}
and I would have an ObservableCollection<Day> Days in my ViewModel, which would be bound in the XAML with this:
<ItemsControl ItemsSource="{Binding Days}">
<!-- ItemsPanelTemplate -->
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<Grid>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition />
<RowDefinition />
<RowDefinition />
<RowDefinition />
<RowDefinition />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
<ColumnDefinition />
<ColumnDefinition />
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
</Grid>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<!-- ItemContainerStyle -->
<ItemsControl.ItemContainerStyle>
<Style>
<Setter Property="Grid.Column" Value="{Binding DayOfWeek}" />
<Setter Property="Grid.Row" Value="{Binding WeekNo}" />
</Style>
</ItemsControl.ItemContainerStyle>
</ItemsControl>
I wrote some examples on how to use an ItemsControl here if you're interested
