clearAll and setDateFormat not working

I’m getting javascript errors when attempting to call those two methods on my grid object, saying that those methods don’t exist. Sure enough, if I debug through a grid object i create, I can’t find a definition for either of those methods. Are these only supported in the pro version, or am I missing a file?

I’m using the most recent free version of dhtmlxgrid, downloaded two days ago.

clearAll should work. As you guessed, setDateFormat is Professional version only. (Note the orange flag in the documentation.)

Chad McCallum is right.
ClearAll() method should work correctly with no doubts. Please, try to update the version of your dhtmlxGrid.
If issue still occurs - please provide any kind of sample to reconstruct the issue

What about setDateFormat() - unfortunately the method requires PRO version of dhtmlxGrid.
