Making the MaintainExtentBehavior works

StéphaneVouillamoz — Fri, 18 Jan 2013 08:47:06 GMT

Hello,

I have the pretty simple map application below. In the code behind I programmatically add the layers and zoom to a particular extent at startup. The map displays as expected. See images in attachment.
But when I resize the window, the map is not adjusted accordingly.
I tried to remove the width and height properties of the map but it then displays a very tiny image...

I would appreciate any hints toward making this work!

Thanks

Vouillas

To get the Map to resize correctly you need to remove the Width, Height, HorizontalAlignment and VerticalAlignment properties., i.e:

<esri:Map x:Name="_map" Grid.Column="0" UseAcceleratedDisplay="False"/>
