 Hi,

 I added two public functions in the file legendctrl.templ for expand or
 collapse a layer or group in legend viewer.

 function ExpandLayerInLegend(expandInLegend,layerName)
 function ExpandGroupInLegend(expandInLegend,groupName)
 expandInLegend is a boolean

 Moreover, for this, I added 6 functions:

 function ExpandLayerInLegend(expandInLegend,layerName)
 function ExpandGroupInLegend(expandInLegend,groupName)

 function FindGroupByName(nodes, groupName)
 function FindLayerByName(nodes, layerName)

 // if expandInLegend==true => node group and all parents of this group are
 expanded
 // if expandInLegend==false => only node group is collapsed
 function ExpandAllGroupParentInLegend(expandInLegend,node)
 function GetGroupByLayer(layerName)


 Thanks
