Treeview

[fifi]

Hi,

again i have a special "problem".

I tried very hard to build a UDF for treeview which returns the ordnernumber of the clicked subitem, but i had no success after some hours of work.

I try to explain this problem:

- Mainitem1

-----Subitem11

-----Subitem12

- Mainitem2

-----Subitem21

-----Subitem22

-----Subitem23

- Mainitem3

For example if Subitem22 is clicked i need to know that it is the second Subitem. So the UDF should return "2". And so on!

Maybe there is a simple way to do this; based on the functions that holger and gafrost have made for treeview the last days?

Thanks

FIFI

Hi gafrost,

thanks for quick helping. Hope this was the last enhancement i needed for treeview.

It works perfectly and i think for other users can your UDF's also be very usefull.
