The current extent of the map.

<DefaultValueAttribute()>
<BindableAttribute(False)>
<ResDescriptionAttribute("The initial extent of the map.")>
<ResCategoryAttribute("Map Behavior")>
Public Overridable Property Extent As Envelope
Visual Basic (Usage)Copy Code
Dim instance As Map
Dim value As Envelope

value = instance.Extent
C# 
[DefaultValueAttribute()]
[BindableAttribute(false)]
[ResDescriptionAttribute("The initial extent of the map.")]

Example

For an example of setting the Map extent using various callback methods, see the developer kit sample "Common_Callback", C# or VB version--see the Default.aspx page.

Remarks

The current extent of the Map may be retrieved or set with this property. There are many other ways of setting the extent as well, such as the Zoom(Rectangle, bool) and CenterAt(System.Drawing.Point) methods.

Be aware that if you set the extent programmatically during a callback, and the Map control does not initiate the callback, then you must pass the Map's CallbackResults back to the page in order for the changed extent to be displayed to the user. For example, if you add a button control to the page and execute it with a callback, and set the Map extent with this callback, then you must pass the Map's CallbackResults via the button back to the page. See Example for directions to a sample.
