Preventing selection of objects drawn in OnRender

[pjsmith]

Hello,

I have an indicator that shades portions of the chart canvas, amongst other things. I DO want to be able to double click / select the plots on the chart from the same indicator, but I don't want the chart regions to be selectable. They are drawn with Draw.FillRectangle. The issue is, clicking almost anywhere on the chart selects one of these objects, which is undesirable. I read in the d2d docs there was a way of doing this without the click events etc attached, which was good for performance etc, too. Is this possible. Selectively draw an object such as a rectangle, and have it not interact with the user, whilst leaving the rest normal?

I know I can disable all for the indie user interaction with HitTest, and via the chart properties for all, but that is not what I want. I just want to prevent it for single drawn objects. I hope this makes sense.

Thanks.

Hello pjsmith,

Thank you for your post.

Custom render code that you do not want to be clickable should be placed within if (!IsInHitTest). IsInHitTest determines if objects drawn in the chart object should be selectable in the hit test. procedure.
