Bing maps Ajax control 7 , removing pushpin useing entitycollection removeAt property. RRS feed

  • Question

  • I have a ajax resultset which returns hotel details and those hotels are being shown on the bing map as pushpin,
    next to the map i have the hotel names with matching checkbox against each hotel and which is checked on first load.
    My requirement is as this- when i need to uncheck the checkbox and click on a updatemap link only the checkbox which is selected needs to be present on the map as pushpin and remaining should get erased. The removeAt does work for odd number's but not for even pushpins. I also noticed that the updatelink needs to be clicked three to four times to get proper result. Please help
