NXOpen.NXException: First parameter is invalid

NXOpen.NXException: First parameter is invalid

(OP)
Hi
I get this error:
NXOpen.NXException: First parameter is invalid

for the blockstyler command:

CODE -->

listBoxName.SelectedItemIndex = 6 

or this command:

CODE -->

listBoxName.SelectedItemIndex = listBoxType.SelectedItemIndex 

Can someone HELP or give me a hint about the resion.

Thank you.

The error occure at RUNTIME

Do its possible that this because listBoxName is empty
And I try to insert a data in the middle of an empty listbox.

What I'm trying to is this:
I have two listboxes one js the master and is contains data.
And one is slave and is empty.

Now the user selects any item from the master listbox the selected item
Go to a string box for editing and after user editing
I need to insert it in the slave box at the same index as master listbox.

RE: NXOpen.NXException: First parameter is invalid

(OP)
I tested it with both listboxes
Containing items.
And still get that error.

Can someone give a clone.

RE: NXOpen.NXException: First parameter is invalid

(OP)
I tried any syntax for
SelectedItemIndex
Without success.

Do anyone know how to use this
Blockstyler property.

Thank you.

RE: NXOpen.NXException: First parameter is invalid

I don't think it is possible to add an entry at a selected Indexposition. It is just "first come, first serve" base.

Only possible solution I could think of is that you, every time the function is accessed, clear the list of entries and fill it with a new list where the changed value is at the correct position.

Hi Ronald
And thank you very much.

That was my thinking and last solution.

Because If the list is very big
it will take very long time.

Thank you again for supporting me.
