Delete drawing objects

[cls71]

Greetings,
I'm developing one indicator that draws lines, arrows and other objects. But I need to delete one or two of them in runtime.

Is there any function or method for deleting of drawing objects ?

Thanks very much.

Ops. Sorry for the post.

RemoveDrawObject();

(I was searching in Help for "delete" and I didn't find nothing)

Hello.

I trying to setup code that will delete an object on the previous bar, if an object is drawn on the current bar.

Variables:
private string tagID;
private int prevCB;

..
DrawArrowDown(CurrentBar.ToString() + "Sell", 1, ff1 + TickSize, Color.Red);

..
prevCB = CurrentBar - 1;
tagID = prevCB.ToString();
RemoveDrawObject(tagID);

In the 'output' window, I see ..

Current Bar = 1614
Current Bar.ToString() = 1614
prevCB = 1613
tagID = 1613

But on the chart, its not removing the previous object. Can you see where I'm going wrong?

Hi R.C.,

The reason is because your object's tags are not only CurrentBar. They are CurrentBar + "Sell".

You need to pass in a string that would be 1613Sell for it to find your object.
