iit's simple .
here is my code in event 'pbm_dwndropdown'
datawindowchilde dw_child
This.GetChild("colname",dw_child)
dw_child.SetDetailHeight(1,dw_child.RowCount(),80)
dw_child.SetFilter(" condition <> i_need")
dw_child.Filter()
dw_child.SetDetailHeight(1,dw_child.RowCount(),0)
dw_child.SetFilter("")
dw_child.Filter()
Then OK.. Tag : PowerBuilder 下拉数据窗口 过滤 displayname
all above refer to http://pbdj.sys-con.com/read/42519.htm
summary:
The trick here is not to filter. You need to have the description or display value in the primary buffer. One method is to use SetDetailHeight to mimic "filtering."
You'll be left with all the rows so the display value can be found but the rows you don't want to see have a height of 0
