Help with Google Map API Example.

[Attaixneima]

Hi, got this Google Map example from this site: http://www.4guysfromrolla.com/articles/052610-1.aspx.

Working great but want to see if can get working with executing a sql server stored procedure rather than a select command. Am confused as to where the 2 parameters are being loaded from and if there is a way to pass them to SQL. Here is the modifed version which goes against our sql server and works fine but want to do a little bit sql code which needs to be in sql so we can bring back more fields but not sure how to change to selectcommand work with executing an stored procedure and not sure where the @Latitude and @Longitude parameters are getting loaded?

Thanks, JoeOf course, 10 minutes after postiing, I think I got it. I was manually changing code but was doing wrong so reconfigured datasource through design view and was able to get going in case it helps anyone else.

<asp:SqlDataSource ID="dsSearchResults" runat="server"
ConnectionString="<%$ ConnectionStringsroduction2ConnectionString2 %>"
SelectCommand="spJJStoreLocations"
SelectCommandType="StoredProcedure">
<SelectParameters>
<asparameter Name="Latitude" />
<asparameter Name="Longitude" />
</SelectParameters>
</asp:SqlDataSource>

A general API means that a full set of an API is in the library of a programming dialect like for example a Java API. For it to be specific, means that the API addresses a specific difficulty for example, Google charts API.
