trouble removing Text objects

[roland_nt]

Get message:
Error on calling 'OnBarUpdate' method for indicator '[routine name]' on bar 14: Collection was modified; enumeration operation may not execute.

I occasionally need to take all drawn text off the screen, Each message has a unique tag. but
RemoveDrawObject(tag) gives this message when I try to loop through all text tags.

Bar 14 is just an arbitrary staring point. Message occurs for any value.

Hello roland_nt,
Thanks for writing in and I am happy to assist you.

You cannot delete any object the collections while in a foreach loop. Thus you cannot use the RemoveDrawObjest(tag) code within the foreach loop.

This is a more of a c# query and please refer here for more details

Please let me know if I can assist you any further.

This thread deals with that exact issue. If you read it, you will get the code to do what you want. http://www.ninjatrader.com/support/f...ad.php?t=44194
