Stretch the diagram

Hello, Stoyan.
I have the following xaml code
Code
Select All
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto" MinHeight="20"/>
            <RowDefinition Height="Auto" MinHeight="25"/>
            <RowDefinition Height="519.723*" />
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="153.75*" />
            <ColumnDefinition Width="10" />
            <ColumnDefinition Width="603*" />
        </Grid.ColumnDefinitions>

       <GridSplitter Grid.Column="1" Width="10" VerticalAlignment="Stretch"
                      Grid.RowSpan="2" Grid.Row="2" ResizeDirection="Columns"
                      ResizeBehavior="PreviousAndNext"/>
        <mf:Ruler Grid.Column="2" Grid.Row="2" Margin="0,0,0,2"
            VerticalScaleVisible="Collapsed" HorizontalScaleVisible="Collapsed"
            Width="Auto">
            <mf:Ruler.Document>
                <mf:Diagram Name="m_Diagram" Height="Auto" Width="Auto">
                </mf:Diagram>
            </mf:Ruler.Document>
        </mf:Ruler>
        <mf:NodeListView Name="m_ElemList" Grid.Row="2" Margin="0,0,0,0"/>

And I want to stretch my diagram on the whole column width. I tried to set HorisontalAligment and HorisontalContentAligment  of my diagram to Strech. But there is now effect. How can I do this thing?

Hi,

You will have to set a larger Diagram.Bounds value. Try doing that from the ruler's SizeChanged event.

I hope that helps,
Stoyan

Hello, Stoyan.
I have the same problem again. I add the tab control and make the my user control from the ruler with diagram. And when I add a TabItem into TabControl I need to stretch the diagram. The different alignments don't get any effects. And I don't know the width and height. They are equal to Double.NaN Sad. And my ruler with diagram is places into the center of TabITem. What I have to do?

Hi,

Are you checking the TabItem's ActualWidth and ActualHeight properties, or Width and Height?

Hi,

Remove the Height="300" Width="300" assignments from the UserControl's Xaml and the control will fill the tab item. In WPF these properties serve to let you override the width and height that would be otherwise calculated dynamically from other properties such as Margins, Alignment, etc.

I hope that helps,
Stoyan
