Aspose connectors are not visible in visio file


#1

Hi,
I am using Aspose API in .net to draw the diagram for visio (.vsdx file). I am using Aspose dll with version 19.4. I need to draw the rectangles with different sizes so rectangles relation can be parent and child or sub layer. I also need to establish the connection in these rectangles using arrow connector.
I am able to draw the rectangles but facing two Issues:

  1. Some rectangles not showing in page, I am not sure why it is not visible I am using SendToBack() function to show the child rectangle. I am attaching the generated and expected visio file.

  2. Arrows are not visible in the page. I applied the following logic:
    I have two loop, First loop for drawing the all rectangles in the page after drawing all rectangles then I am starting the second loop to draw the arrows for establishing the connections in rectangles.

Please find the attachment of expected and generated files.
Please let me know the solutions for above two issues.

Could you please share complete sample code snippet which you have tried along with sample input Stencil and Diagram file. We will test the scenario in our environment and address it accordingly.
