i have seen event "currentitemchanged" of dataform (on childform) fired.
but textbox stay empty without error message...
at debug time :
directcast((new system.collections.generic.mscorlib_collectiondebugview(of object)(directcast(df.currentitem,system.windows.controls.datagridselecteditemscollection).selecteditemscache)).items(0),ria.web.lx_lexique).nom
return right value...
