Deleting objects of a certain type from graphView

Having some trouble deleting all objects of a certain type from a GraphView. Using the following code which attempts to delete all objects of type “GraphPolygon”.

<br />GraphView canvas; <br /> <br />foreach (GoObject obj in canvas.Doc.DefaultLayer) <br />{ <br /> if (obj is GraphPolygon) <br /> { <br /> canvas.Doc.Remove(obj); <br /> } <br />} <br />

For some reason it deletes all except for 1 of them.

You’re modifying the collection you are iterating… a no-no. Make it:

foreach (GoObject obj in canvas.Doc.DefaultLayer.CopyArray())

Hehe thanks. Oops that was a dumb mistake.
