How to delete rows in DropdownCommandInput

[Anonymous]

Hello. It need delete rows in DropDownCommandInput if button delete is pressed. I try this code

dropDownCommandInput=adsk.core.DropDownCommandInput.cast(inputs.itemById(piecesListId))
    if dropDownCommandInput:
        for item in dropDownCommandInput.listItems:            
            item.deleteMe

I try delete all rows and add new rows, but only new rows are added.How delete all rows in DropDownCommandInput?

You've gotten caught by a common Python programming error that I've made several times myself.

item.deleteMe

should be

item.deleteMe()

Your current code is just getting a reference to the deleteMe function while the second one is executing it.

Sorry it was my mistake. I try this code, but one row still remain.

    dropDownCommandInput=adsk.core.DropDownCommandInput.cast(inputs.itemById(piecesListId))
    dropdownItems=dropDownCommandInput.listItems
    count=dropDownCommandInput.listItems.count
    index=count-1
    while index>=0:          
        row=dropDownCommandInput.listItems.item(index)
        print(row.deleteMe())
        index-=1

row.deleteMe() return False if index=0

how to remove last Row?

I'm not exactly sure why your code isn't working.  I didn't take the time to debug it, but this simpler version is working for me.

    dropDown = eventArgs.inputs.itemById('dropDown')
    for i in range(0, dropDown.listItems.count):
        print(dropDown.listItems.item(0).deleteMe())

We also have it on our backlog to add a "clear" method to the ListItems class to make this much easier.

dropDownCommandInput = inputs.itemById(piecesListId) 
    for i in range(0, dropDownCommandInput.listItems.count): 
        print(dropDownCommandInput.listItems.item(0).deleteMe())

print False( , and no one row is not delete.

but if add Breakpoint and write in console 

dropDownCommandInput.listItems.item(1).deleteMe()

return true

I don't know what the difference could be.  I just double-checked my test and it's returning True for every delete.  What type of drop-down are you testing with?  I'm using check boxes.

commandInputs_.addDropDownCommandInput(piecesListId, 'Piece', adsk.core.DropDownStyles.TextListDropDownStyle);

Active Row is not deleted. It need delete all old rows and set new list of rows.

I've verified the problem with a text list and also see that it's not allowing the selected item in the list to be deleted.  The only workaround I can see now is:

1. Delete all of the items in the list except for the selected item.

2. Add your new items to the list and have one them selected.

3. Delete the first item in the (which will be the one left over).

No chanses :), I am crying. When in list remains 2 rows. Both rows have status isSelected=True, and no one is not deletable

def deleteSelectedRow(inputs):
    dropDownCommandInput=adsk.core.DropDownCommandInput.cast(inputs.itemById(piecesListId))
    count =  len(dropDownCommandInput.listItems)
    first=True
    
    for piece in currentPiecesSet.pieces:

        if first==True:
            dropDownCommandInput.listItems.add(piece.name, False, '')
            first=False
        else: dropDownCommandInput.listItems.add(piece.name, False, '')
    dropDownCommandInput.listItems.item(1).isSelected=True
    
    for i in range(0, count): 

        dropDownCommandInput.listItems.item(1).isSelected=True
        dropDownCommandInput.listItems.item(0).deleteMe()
        
    print(len(dropDownCommandInput.listItems))

code without garbage

def deleteSelectedRow(inputs):
    dropDownCommandInput=adsk.core.DropDownCommandInput.cast(inputs.itemById(piecesListId))
    count =  len(dropDownCommandInput.listItems)
 
    for piece in currentPiecesSet.pieces:
            dropDownCommandInput.listItems.add(piece.name, True, '')
    
    for i in range(0, count): 

        dropDownCommandInput.listItems.item(1).isSelected=True
        dropDownCommandInput.listItems.item(0).deleteMe()
        
    print(len(dropDownCommandInput.listItems))

It looks like a Bug, or I am not right?

Has this issue been fixed or a solution found? I am having exactly the same problem.
