Dynamic Update of Value list Filter

Question

Hello,

Please I am working to dynamically update a value list  where by If the user enters : "Taucher" in the second parameter, the third parameter  will dynamically contain the list that belong to what is selected in the second Parameter. If "Kormoran" is selected in the second parameter, the third parameter  will dynamically contain the following list that belong to what is selected in the second Parameter. My validation code looks like this but it does not seems to have any effect: Please I need help to solve the issue. Thanks

I haven't fully tested it, but you might try this for the tool validator: import arcpy class ToolValidator(object): def __init__(self): self.params = arcpy.GetParameterInfo() def initializeParameters(self): self.params[0].filter.list = ["Taucher", "Ganse", "Kormoran"] self.params[0].value = self.params[0].filter.list[0] # default: Taucher self.params[1].filter.list = ["Haubentaucher", "Zwergtaucher", "Prachttaucher"] self.params[1].value = self.params[1].filter.list[0] # default: Haubentaucher return def updateParameters(self): if self.params[0].value not in self.params[0].filter.list: # set defaults self.params[0].value = self.params[0].filter.list[0] # default: Taucher self.params[1].filter.list = ["Haubentaucher", "Zwergtaucher", "Prachttaucher"] self.params[1].value = self.params[1].filter.list[0] # default: Haubentaucher elif self.params[0].value == "Taucher": # Taucher selected self.params[1].filter.list = ["Haubentaucher", "Zwergtaucher", "Prachttaucher"] # update list if self.params[1].value not in self.params[1].filter.list: # if selection not in list self.params[1].value = self.params[1].filter.list[0] # first option becomes default elif self.params[0].value == "Ganse": # Ganse selected self.params[1].filter.list = ["Brandente", "Nonnegans","Saatgans"] if self.params[1].value not in self.params[1].filter.list: self.params[1].value = self.params[1].filter.list[0] elif self.params[0].value == "Kormoran": # Kormoran selected self.params[1].filter.list = ["Kormoran"] if self.params[1].value not in self.params[1].filter.list: self.params[1].value = self.params[1].filter.list[0] return def updateMessages(self): return ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Hope it helps.
