Map Tip line graphics?

ShawnaErnst — Tue, 15 Mar 2011 17:40:46 GMT

Hello!

We're trying to create a map tip for line graphics, but it seems that the cursor isn't "sensitive" enough to actually find the line.

So, we're now trying to query our map service to get a line graphic, then buffering that line graphic to get a polygon and then passing the polygon buffer back to the map service to query for a line...and then finally map-tipping the line. That solution works (sort of) - we get a map-tip, but we have problems where our buffers overlap.

Is there a better way to create map tips for lines?

Thanks
Shawna

Which MapTip are you using?

Can you share your line symbol? MapTip in both cases open when graphic element is entered. I wonder if your symbol template include IsHitTestVisible="False" somewhere.

Could you make your lines wider?
