Hi All
I am using google map in my asp.et applicaiton. Here the employe can draw a location on the map and he can save the selected location to the database (latitudes and longitudes for the location). I can draw a rectangle using javascript but can't access the points defined for the rectangle during postback.
The issue is during postbakc the values stored in the hidden variables get cleared. Can anybody suggest me a workaround to solve this issue.
Thanks in advance.
Regards,
samitha

This would not happen automatically. You have written some code and the way it is written clears the data. Use DEBUGGER, look into it why and when it gets cleared.
It is not a normal behavior where a workaround is needed. Simple code fix should do.

I am trying to strore values (latitudes and longitudes) in a hidden field inside the javascript that draws the ploygon as I can't access those points directly in code behind. The valuses get stored in the hidden filed. As soon as I click the save button a postback call is generated and values stored in the hidden field get cleard. This is the problem I am facing. My requirement is to get the values for each of the points in the polygon.

I recommend you to use [ARTEM GOOGLE MAP CONTROL] for this.. you wouldn't need to use hidden fields and all that.. just drag control on your page and start using it.

Even though ARTEM GOOGLE MAP CONTROL provies more options I'm still having problems with it. It generates a serialization error when i try to store the location details. Can anybody suggest me any solution for this?
