Hello,

Is there a way to turn off the zoom and pane controls?  Ideally I just want the map to sit over a country and not be moved.

Additionally is there an easy way to display hover text in a bubble when hovering over geo polygon location?

Thanks!

Hi,

Constraining the zoom is easy enough, just set minZoom, maxZoom and zoom to the same value.

Disabling the panning is a different matter, as there's no built-in option to control it.
This as an omission that we'll address in the next internal build by adding a "pannable" option. We'll also add a complimentary "zoomable" option. Both will apply only to user interaction, not to the API.
A rather nasty workaround would be to destroy the map scroller:
$("#map").data("kendoMap").scroller.destroy();

The shapeMouseEnter and shapeMouseLeave events are suitable for your second requirement. You can show a Window at the mouse coordinates with data for the particular shape.

I hope this helps.

Hi,

Thanks, much better than my nastier work around for pannable.  I was having it redraw the map if it detected a pane action!  While it worked just fine, it added a sort of 1/2 sec lag if you looked closely.

As far as my second requirement, I was more hoping that the API actually had a built in tool tip like in bar charts, etc..  I could certainly get a second library to do this as well, but it would be easier to have it wrapped in the map API.

Thanks for the help :)

Hello,

The zoomable and pannable options are now live in the latest internal build. No hacks required, just an update.

We're considering a built-in tooltip for the shapes. There are a few technical difficulties regarding this feature, most notably performance related.
I hope we'll have a solution ready for the next major release.

Thank you for your feedback.
