Cast Text from DrawObjects

[kenz987]

From the Help Guide: Lets say this is in Indi_001:
Text myText;
protected override void OnBarUpdate()
{
if(CurrentBar==50) myText=Draw.Text(this,"tag","test",0,High[0]);
if(myText !=null ) Print(myText.Anchor.DrawnOnBar);// drawn on bar 50
}
.. then in Indi_002 I want to retrieve that text. I can get it with a foreach loop looking at all the tags for "tag"
But I know the tag, so I try to read it directly with DrawObjects["tag"] and I can get it semi OK
It shows me the Tag.
But when I try to show DisplayName I get all sorts of errors for bad cast etc. Ive tried all sorts of combinations to get this, and even one that looks right and compiles. But it gives a run-time error of no instance assigned etc.
I need to see DrawObjects["tag"].DisplayName and then Time.
"missing a using or cast.??.."

Hello kenz987,

Thank you for your post.

If you want to get the actual text you would need to use DisplayText, not DisplayName. Please see this forum post that discusses:

Please let us know if you have any further questions.

Thanks Gaby, But thats no help. I want to avoid a loop. My Count gets very large. I have the tag, how do I get the data with DrawObjects["tag"] . . ??

The same concept still applies, you would access it from the DrawObjects collection via the tag.

https://ninjatrader.com/support/helpguides/nt8/drawingtools_drawobjects.htm

if (DrawObjects["someTag"] != null && DrawObjects["someTag"] is DrawingTools.Text)
{
DrawingTools.Text myDrawText = DrawObjects["someTag"] as DrawingTools.Text;
Print(myDrawText.DisplayText);
}
