VisualBrush at Runtime BUG?

Hi,

I'm filling a visualbrush using a custom control at runtime. I have something like this in my main window:

In the code behind:

void Window1_Loaded(object sender, RoutedEventArgs e)
{
customControl = new CustomControl();
visualBrushCustom.Visual = customControl ;
.....

BUT The customcontrol is not rendered as visualBRush. If I insert the customcontrol inside my window and then redirect the visualbrush to that control it works.

Is it normal Do you know a workaround

Thanks

Giorgio

I had to call

myPerspectiveCamera.InvalidateArrange();

for it to show up when the window loads

try this

VisualBrush vb = FindName("visualBrushCustom") as VisualBrush;

vb.Visual= cc;

Of course I can...

This is the xaml:

<Viewport3D Width="800" Height="600" Name="myViewport" Focusable="True" MouseLeftButtonDown="HitTest">

<Viewport3D.Camera>
<PerspectiveCamera x:Name="myPerspectiveCamera"
FarPlaneDistance="15" LookDirection="0,0,1" UpDirection="0,1,0" NearPlaneDistance="1" Position="0,0,-3" FieldOfView="50" />
</Viewport3D.Camera>

<ModelVisual3D x:Name="topModelVisual3D">

<ModelVisual3D>
<ModelVisual3D.Content>
<AmbientLight Color="#333333" />
</ModelVisual3D.Content>
</ModelVisual3D>
<ModelVisual3D>
<ModelVisual3D.Content>
<DirectionalLight Color="#FFFFFF" Direction="-0.612372,-0.5,-0.612372" />
</ModelVisual3D.Content>
</ModelVisual3D>
<ModelVisual3D x:Name="side1ModelVisual">
<ModelVisual3D.Content>
<GeometryModel3D x:Name="side1GeometryModel3D" Geometry="{StaticResource CubeSide01}" >
<GeometryModel3D.Material>
<DiffuseMaterial>
<DiffuseMaterial.Brush>
<VisualBrush x:Name="visualBrushCustom"></VisualBrush>
</DiffuseMaterial.Brush>
</DiffuseMaterial>
</GeometryModel3D.Material>
</GeometryModel3D>
</ModelVisual3D.Content>
</ModelVisual3D>

</ModelVisual3D>

</Viewport3D>

This is the codebehind:

public partial class Window1 : Window
{

CustomControl customControl ;

public Window1()
{
InitializeComponent();

this.Loaded += new RoutedEventHandler(Window1_Loaded);
}

void Window1_Loaded(object sender, RoutedEventArgs e)
{
customControl = new CustomControl();
visualBrushCustom.Visual = customControl ;
}
}

And this is the code of CustomControl:

<Grid x:Class="Prova3D.CustomControl"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

>

<TextBox Width="200" Height="50" Name="txtX"></TextBox>

<Button Width="50" Height="50" Name="btnOne"></Button>

</Grid>

Hope now it's cleaner...
Thanks for your help

I'm sorry,

but this is not the answer to my question....

can you post a little bit more code so the context is more clearer

it draws the customcontrol, but for some reason it is visible only after you try to resize window

Thanks! That really solved the problem!! I used:

myViewport.InvalidateArrange();

Thank you very much Lee d.

if visualbrush is a resource, you have to find the resource by the name and then set the visual. it does work correctly
