Saving(Creating) diagram as image.

Hi

Am drawing some diagram with different types of the nodes (shape node and control nodes). now i need to save the diagram

as image. am using the following code to save the diagram as image. It is saved but the control node is not saving as image

simply a blank box is showing in the place of control node.

Can you help me what will be missing to see the control node also.

FYI : am adding the the user control to the control node ie some Chart(Graph) control.

The code is :

dim diagramImage As Image = Me.doc.CreateImage()

Thanks

Hamid

Hosted controls are rendered in the exported image only if they are native .NET controls that paint themselves in the OnPaint method. If a control is a wrapper around a Win32 control, Flowchart.NET cannot make it render itself on the bitmap's Graphics. You must handle the PaintControl event to implement image export and printing for such controls.

I hope that helps,
Stoyan
