Stoyo, me again now i have a new problem.
Sorry for all large list of questions but i need stay secure all what i need work, before order a licence.

I continue working on the example FORMEDITOR
I make some simple changes to the formeditor, but cant make the form use all screen:

Here the changes:
<Window x:Class="FormEditor.Window1"

Width="703" Height="570"
Loaded="Window_Loaded" Name="window" Icon="/FormEditor;component/App.ico" AllowsTransparency="True" WindowStyle="None" Background="Transparent" WindowState="Maximized" >
<Grid>




<d:Diagram Name="form" BackBrush="Black"
SelectAfterCreate="False"



NodeCreated="form_NodeCreated"



NodeActivated="form_NodeActivated"



InitializeNode="form_InitializeNode"
NodeSelecting="form_NodeSelecting"

</d:Diagram>




<ListBox Height="100" HorizontalAlignment="Right"


Margin="0,13,101,0" Name="palette" VerticalAlignment="Top" Width="120"


SelectionChanged="palette_SelectionChanged" >


<ListBoxItem>Button</ListBoxItem>


<ListBoxItem>TextBox</ListBoxItem>


<ListBoxItem>Label</ListBoxItem>


</ListBox>


<Button Height="23" HorizontalAlignment="Right" Margin="0,13,11,0"


Name="btnSave" VerticalAlignment="Top" Width="75" Click="btnSave_Click">Save</Button>


<Button Height="23" HorizontalAlignment="Right" Margin="0,52,11,0"


Name="btnLoad" VerticalAlignment="Top" Width="75" Click="btnLoad_Click">Load</Button>


<wfi:WindowsFormsHost Margin="0,124,11,13" HorizontalAlignment="Right" Width="210" Background="Black">


<f:PropertyGrid Height="23" Margin="0,82,11,0" x:Name="propGrid" />


</wfi:WindowsFormsHost>


</Grid>
</Window>

++++++++++++++++++++++++++++++++++++++++++++++

New CODE:

private void Window_Loaded(object sender, RoutedEventArgs e)

{

WIDTH = SystemInformation.PrimaryMonitorSize.Width;

HEIGHT = SystemInformation.PrimaryMonitorSize.Height;

form.Width = WIDTH;

form.Height = HEIGHT;

You can see the form never cover all the screen.
Why?
is like form can be more bigger.
Is really strange.

Thnakyou that fixed the resize thing.

I continue checking now  : )
