getrow() not return proper row number after using the modify() function

Hi Everyone,

I am using PowerBuilder 11.1 build 8123.

I am protecting the column and changed the background mode of data window column through modify() function in user defined local function (where datawindow is argument type and pass by is reference). Data window have more than one row and one selected row. Before modify the column's, getrow() function return right selected row, but after modify it return any other row number. code is written in fwc_retrieve event.

I also use scrolltorow() and setrow() functions after modify(), but these have not worked.

In my application PFC is used. I don't able to find out the reason.

Please help.

Thanks,

Vikrant
