Social Networking :: Filter And Display Google Map Markers From DB Based On DropDownList Selection
May 7, 2015
in our project we need to show the markers on Google map from the database. we have already got the code in which all the markers are displayed for the the places stored in database. But our aim is somewhat different.We need marker on one place that is selected from the database.to elaborate,if we select an area from the dropdownlist that contains names of areas stored in database,then "only" marker on that place must be displayed.Further,selecting the subarea from dropdownlist2 should zoom the map and display a marker on that subarea.so how do we do that? what are the changes required to be made in this code?

i want to include google maps API into my ASP.NET page and allows users to input the locations(few places) they are going to visit. When the user inserts the location, the google maps API will mark these locations. It means in the maps it will mark the places. some red bubble to indicated the places is marked.
for example,i list a few checkboxes beside the check boxes will have a places'name. when the checkbox is checked, Google maps will make markers on these location. How to do this?
IF after the places is marked in google maps, i want to get some information from google maps (such as the coordinates of the all the marked place). Then, use google maps to run some code behind to find the shortest path using Travelling Salesman Problem (TSP) algorithm.
After that,generate the proper sequences of the places ( which place to go first, and which place to go last). is it possible to be done?
