嵌套数据窗口子数据窗口的点击行

Is it possible to get the row number clicked by a User in a
nested report - not composite. Just one nested datawindow in
another datawindow.

I need to access a value in a clicked row and I can't even
get the row!

In the ItemChanged event of the datawindow add this code

DataWindowChild ldw_child

if dwo.name = 'sales_summary_acrs_the_bor_bene_nm'    then  // column user
clicked
 dw_1.GetChild('sales_summary_acrs_the_bor_bene_nm',ldw_child)  //get ref to
child datawindow
 messagebox('clicked',' row is ' + String(ldw_child.GetRow())) // get row
number
 messagebox('data ' , 'data is ' +
ldw_child.GetITemString(ldw_child.GetRow(),'mxf_entry')  //get data value
from child collumn)
end if

Two big problems there:
You'd want the Clicked event, not ItemChanged
GetChild doesn't, can't, never did, access a *nested* DW. Read the Help -
DDDW and reports within a composite, period.
You might get to properties with dot notation, but not events.

Maybe you could redesign the DW as grouped - current base row in the group
header, current nested as detail.
