Urgent - Using Dojo DataGrid with ArcGIS JavaScript Extension for Google Maps

StephenLopez — Tue, 01 Jun 2010 12:13:36 GMT

I am attempting to implement the dojo datagrid using the find task thorugh the ArcGIS JavaScript Extension for Google Maps. I have successfully created a map using the Javascript API that zooms to a point when you click on a row in the datagrid, but am having difficulty making this work within the Google Maps framework. I have posted my code, I know there are arrors, but I am having a hard time getting them worked out, even using Firebug to help me.
Any help would be appreciated. If you would like to see my successful implementation for the javascript api I can post that as well, just let me know.

Thanks.

First, try to use the CODE tags when posting code. Otherwise it's unreadable without some effort.

The first error I get in Firebug is

dojo.addOnLoad(init);

This is pretty easy because you have no function named "init". Change it to:

dojo.addOnLoad(initialize);

Next, I see "grid is not defined" at this line:

dojo.connect(grid, "onRowClick", onRowClickHandler);

It looks like you have no "grid" variable declared.

Start with that.
