I need to customize the appearance of the InfoWindow in order to make it a balloon with the "arrow" on the side of it, but when i tried to customize the style using Blend, I could'nt change the shape of the Border. Does anyone knows how to do it?
The info window seems to build everything up in code, not done through template styling. I ended up creating a MapTip to do a similar task for this reason. You can download the InfoWindow code off Codeplex http://esrisilverlight.codeplex.com/ and see where they are building up the border (BuildBorderPath method), you may be able to change for your needs and use a customized version
