What could
cause a KeyNotFoundException for the following line of code in protected override void DrawCore(GeoCanvas
canvas):
EditShapesLayer.Draw(canvas, labelsInAllLayers);
?
KeyNotFoundException EditShapesLayer.Draw
Hi F5K,
Thanks for your post, would you please provide us the stacktrace for a further test, for now the information is limited to locate the bug location.
Waiting for your further information.

It gives the exception in my override of DrawCore:
Collection<SimpleCandidate> labelsInAllLayers = new Collection<SimpleCandidate>();
EditShapesLayer.Open();
EditShapesLayer.Draw(canvas, labelsInAllLayers); //<== KeyNotFoundException
Additional info:
In my user interface, the user gets to click on features on the map and edit them using standard EditShapesLayer functionality. The exception has so far never occurred the first time the user clicks on one of the features to edit it, but it does usually happen within the second to fifth attempt. The exception can both occur when the user attempts to edit the same feature as edited before, or when he/she selects another feature. So far I’ve been unable to find a predictable pattern.
Hi F5K,
Thanks for your further information, I tried to recreate your problem with attached code, but it didn't show up, would you please check if there are any thing we missed in our test code?
Waiting for your further information.

I couldn't
recreate the problem with your code either, so I've rewritten it to be more
like my own code, but much simpler. So far this has helped me to discover the
problem doesn't so much lie in the fact that I override DrawCore. I can get the
KeyNotFoundException by commenting out the override and simply refreshing the
map.
Please try
out the attached code and see if you can get the same error by doing the
following:
- Select the
line by clicking on it - Move the
line by dragging it - Click anywhere
else in the map to deselect it - Reselect the
line, again by clicking on it
I'm still on 7.0.287.0, while waiting for 289
to become available.

By the way, I have a feeling that somewhere along the DLL updates I lost a lot of performance. This example has a map with just one feature in it and yet it takes seconds to start up.
Hi F5K
Thanks for your further informaiton, the problem is recreated, would you please use
editOverlay.EditShapesLayer.BuildIndex();
winformsMap1.Refresh(editOverlay);
To Replace
winformsMap1.Refresh(editOverlay);
now it should work
Hope it helps
Summer
I’ve copied your code into my DrawCore override so that I don’t have to call it everywhere I want to refresh the EditsShapesLayer. So far it looks like it works! Thank you!
How about the performance issue? Did you also notice long loading times with the sample code I attached? If so, what is taking so long?
Hi F5K
First of all, great to hear it helped, about "performance issue" did you mean that you attached a sample in reply "03-27-2014 10:56 AM "? if yes, it seems that the upload was not successful,would you please send it to forumsupport@thinkgeo.com?
Waiting for your further information.

No I meant the one called SelectFeatures.txt posted in this thread at 03-27-2014 10:52 AM. I’ve reattached it.

Hi F5k,
Thank you for your mentions, we have some diagnostics statements in our product. I’m working on cutting off these statements from desktop edition. As so far, when you press “F5”, the performance is slow, but “ctrl + F5”, it is faster. the latest version 7.0.295.0 can be downloaded.

Casper
Hi Casper/Don,
Ok! Please let me know when there is a new dll with better performance.
Sure, once it’s corrected, I will update it in the thread. Sorry for the inconvenience.
Thanks,
Johnny
Hi,
We have fixed this issue, please download the latest version 7.0.308.0 or later. If you have any question, please let me know.

Don
Huge improvement! Thanks!
Hi,
