I have added a button in the tree view ie. sale order line view. So when i open a sale order, i could see the button on each order line. Button is working as expected. The problem is after button click, the focus goes to the first row of the order line. So even if i click on the button of 95th line, the focus goes to the first line. So each time i have to scroll down or paginate back in order to go back to the next line.
