When Bing map control loads for first time on any开发者_如何转开发 browser all pushpin on map are visible. Bing map control renders perfectly.

Then I refresh browser it create rendering issue some custom pushpin on map gets disappeared. This behavior continues with pushpin. Pushpin are (.png) images and I am not using default bing map thumbtacks.
