Datawindow Query


I have a datawindow control which i am using to assign different datawindow objects based on the selection of certain conditions. We have a AFC layer that contains objects specfic to our application which is basically inherited from the PFC layer. I have a function in one of the user objects defined in the AFC layer to format the sql's for all the datawindows dynamically based on the search condition selected by the users for each and every screen/report.
I want to perform an action based on the tag value of a column from a particular datawindow.  For ex.
lets assume we have datawindow  dw_1 which contains column1, colum2, column3.
I want to perform the following logic
If dw_1.object.column1.tag = 'OK' then
   <perform your check>
else if
   <do not perform your check>
End If.

this is a straight away method if i have only one datawindow control/object. In my case i need to get the column name of the appropriate datawindow object that is assigned to the datawindow control for a specific screen and then assign that column/control name to the command line 'dw_1.object.column1.tag ' to perfom the action i need. Can anybody shed me some light on how to go about this..

Please let me know if you need some more clarifications on my request.

you can use getcolumn() and gecolumnname() function to get the column no/name from a datawindow and then use Describe function to get the property value instead of '.object 'notation.

See code snippet for example


string ls_colname,ls_val
ls_colname = dw_1.GetColumnName()
ls_val = dw_1.Describ(ls_colname+".tag")
If ls_val = 'OK' Then
End If
string ls_colno,ls_val
ls_colno = string(dw_1.GetColumn())
ls_val = dw_1.Describ("#"+ls_colno+".tag")
If ls_val = 'OK' Then
End If

Open in new window

Hi Sandeep,

thanks for your hint. I could not get the column name in the user object function since only the base sql of the datawindow is passed to function as an string argument.  
Neverthless, i used describe method to satisfy my need as described below.

   ll_Poscolumn = Pos(ls_BeforeLike,".",1)
   ls_column_name = Trim(Mid(ls_BeforeLike,ll_Poscolumn+1))
//            ls_check_upper = idw_requestor.object.productcode.tag
   ls_check_upper = idw_requestor.Describe(ls_column_name+".tag")
      IF ls_check_upper <> 'NU' then
      END IF

Many thanks once again for your time on this issue.
