Thanks MJG

Actulay I have already cheched all this topics & worksheet

there is no answer to me on there

[MJG · Accepted solution]

See attached.  You needed to put list values in quotes and account for ListIndex<0 (when you change Material, the previous value for Section becomes invalid, so ListIndex goes to -1).

See the attached worksheet. Look for the dynamically controlled listboxes.

Thanks Richard

I have seen this file and leanned alot of that , but unfortunately there is not any dynamicly ComboBox inside the file 

I saw dynamiclt list box but script codes are diffrenet 

anyhow MJG fixed main part of my problem with his reply I just know need to know how to makes automatic list updated after choosing material in the first combo box 

in listbox control the code is ListBox.ResetCount but I do not know what is equivalent in ComboBox

thanks again

rreyhanian,

The method for creating the list options in a ListBox was to add list values.  Therefore, it was necessary to clear the current list before adding the new list options.  The method that you are using to create the list options in the combobox automatically overwrites the existing list, so there is no need.

Edit: I assumed you were referring to ListBox.ResetContent().  If you truly meant Listbox.resetCount, I'm not sure what you mean - please clarify.

Yes exactly I mean ListBox.Reset.Count but based on your reply I do not need that because in combo box it is automaticly updated but as you see the list of avlue in second combo box is not updated until I click on it

but in dynamicly list box is not like that and after selecting in the first list box , second list box will automaticly is updating before you click on it

this is the think I am looking for ...

Edited : I attached a listbox  example which is updating quickly after first choosing

I found it

that is in attaced  file 🙂
