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

EDIT -- For ArcObjects

You can get the extent of selected graphics using IGraphicsContainerSelect.SelectionBounds. This will return an IEnvelope which you can use to set the extent on your IActiveView.

var graphicsSelect = pGraphicsContainer as IGraphicsContainerSelect;
var extent = graphicsSelect.SelectionBounds;
activeView.Extent = extent;
activeView.PartialRefresh();

On the Edit Menu, there is a Zoom to Selected Elements tool.
