Original User: kenbujaTo solve the multiple popup windows problem, I changed the testing code
//PopUp Window on DataGrid
var obj:Object = featureSet.attributes;
var myfloatdg:MyFloatDG;
myfloatdg = MyFloatDG(PopUpManager.createPopUp(myMap,MyFloatDG,false));
PopUpManager.centerPopUp(myfloatdg);
to this:
//PopUp Window on DataGrid
var obj:Object = featureSet.attributes;
// var myfloatdg:MyFloatDG;
if (myfloatdg == null)
{
myfloatdg = MyFloatDG(PopUpManager.createPopUp(myMap,MyFloatDG,false));
}
myfloatdg.visible = true;
PopUpManager.centerPopUp(myfloatdg);
For the datagrid interaction, you didn't include any functions to operate the ItemRollOver and ItemRollOut events for the datagrid. These are the changes I made to your code (which includes a change in the closeMe function to deal with the multiple popup problem)
