Save custom element problem ArcObject Add-in.
Hi ,
I develope command with ArcObject SDK Add-in for 10.5 ArcMap.I created my own polygon element (MyElement) inherit PolygonElementClass , IElement, IPersistStream for Index Maping jobs in ArcMap for customers .But I have problem when I save and open document after adding my Element (MyElement) in GraphicsContainer.
Here is below my class and adding to IGraphicsContainer codes. With below code I can Add my own element on the GraphicsContainer but but after save this document ArcMap crashes and gives exception like below.
When I Add simple ArcObject Polygon element (IElement element = new PolygonElementClass()) there is not any problem when opening and save document.
How can I sove this problem ? Can you help to me ?İs It Add-in support save objects using like IPersistStream ? Here is the codes and pictures below:
Codes :
public class MyElement : PolygonElementClass , IElement, IPersistStream
{
public IEnvelope Env
public string Name
.....
.....properties,functions.etc.
}
ICompositeGraphicsLayer cGLayer = ArcMap.Document.FocusMap.BasicGraphicsLayer as ICompositeGraphicsLayer;
IGraphicsLayer gLayer = cGLayer.AddLayer("Scale_1:1000", null);
...seting scale graphicLayer (ex: 1:1000)
IGraphicsContainer gCont = gLayer as IGraphicsContainer;
foreach (MyElement myEl in myElArray)
{
gCont.AddElement(myEl,0);
}
