how to stop the cursor position.....

Hi..See the image..

This is my small addon

When ever i click on the menu

the add on is opened

there are some fileds..

emp name and doc no..

suddenly the cursor is going to the doc field..

my requirement is how can i stop the cursor exactly at item 222 ( emp name uid)

i had seen some info in forum

and tried this one

oitem = oform.Items.Item("222")

oitem.Click(SAPbouiCOM.BoCellClickType.ct_Regular)

but it won't work

the screen is behaving strange behaviour

it menas it is strucking..

how can solve this problem..

and allso what is diff between omatrix.rowcount and omatrix.visualrowcount

i had used both

bu both are achieving the same targets

why two options for same functionality..
