How to zoom in/out selected elements of MapControl ?

TaiBui — Mon, 19 Aug 2013 02:55:23 GMT

Hi everyone,

I have a mapcontrol that includes many elements: text, line.
I used this code to add elements into mapcontrol: pGraphicsContainer.AddElement(pElement, 0);

I can use zoom button to zoom in/out the mapcontrol, but how can I zoom in/out only seleted elements ?

Is there any buttons for this purpose in Arcgis ?

Thanks and regards,

Tai

Are you wanting to call an existing desktop button? If so, there is the Zoom to selected elements which is found under the Edit menu. You could call this? Have a look at this page and look for esriArcMapUI.ZoomToSelectedGraphicsCommand.

Thanks Hornby,

But this require a IMxDocument object to get commandBars, but I only have the IMap (FocusMap of my pagelayout control):

myPageLayout.ActiveView.FocusMap

How can I do that ?

Tai,

Looks like you are building an Engine based application. I have personally not done that, but look here, have a look at the onCreate method.
