I want to add datasets to ArcMap and place them in a particular group layer by simply clicking on hotlinked polygons in a shape file. The same process is easy in MapInfo and I want to implement the same for ArcGIS 10.
I found the following post http://forums.arcgis.com/threads/8236-Hyperlinks-in-ArcGIS-10 that describes the process in 9.3.1
On properties-->html popup you can load url and any file will open in an external program but I want it to add to the current workspace.
A solution similar to mapinfo--layer control--hotlinks will be ideal but a python based solution will be acceptable as well if it can be added to the relevant vector layers within an mxd.
