Need some help with a new idea. I want to access the tag of selected manually drawn chart drawing. I know how to create the button events and button, write the message, and everything else except how to extract the tag of the selected drawing:
1) Click a button
2) Message: "Select upper TL"
3) User clicks on a manually drawn TL
4) Get the tag of the selected chart drawing
...

Any one know if and how this is possible?
Thanks

I'm not in front of my computer right now, but have you had a look at ChartControl? Or maybe there is sth like GetSelectedDrawObject or similar....

Never used ChartControl before, but looks like there are a lot of useful tools in that. I will play around with it when I get home.

So I figured out how to extract the tags using DrawObjects, now I just need to access the selected drawing only...any ideas?

Is there maybe a way of checking if the object is active/selected? Like a flag or event or so?

Wish I knew, but I can't find any way. I could draw the tags on the chart automatically, and then have an input box for a mini buy program or sell program. Do you know if a dynamic input box would be possible?

Theoretically there are very few limits...but I think that would be more complicated than neccessary. When you access a drawobject, is there no way to get its state? If there were you could simply loop through them...
I'll have a look tomorrow morning, maybe four eyes see more than two...

It has to be in ChartControl somewhere, question is where

@vvhg

Someone sent me the solution to this a couple minutes ago, thought you might want to look at it.

 

Code

FieldInfo fi = typeof(ChartControl).GetField("selectedObject", BindingFlags.NonPublic | BindingFlags.Instance); if (fi != null) { if (base.ChartControl != null) if (fi.GetValue(base.ChartControl) != null) Print(fi.GetValue(base.ChartControl).ToString()); }

This will give you something like:
Name='Ray' Time='9/25/2012 4:32:28 PM', StartBar='2995' StartY='91.10' EndTime='9/25/2012 5:00:00 PM' EndBar='3034' EndY='90.99'

So now I just have to add it to a mouse event, and get to coding.
