The error means that at that time value of oBrw is NIL.

Hi Mr. Rao,

My code is below.

Code: Select all  Expand view  RUN

    @ 45,5 XBROWSE oBrw OF oDlg;
        COLUMNS 1, 2, 3, 4;
        HEADERS "Ürün No", "Tutar", "Karşılık", "Açıklama" ;
      ARRAY TD_UrunNo ;
      PIXEL ;
      SIZE 180,250 UPDATE FASTEDIT
     
    if ! Empty( oCol := oBrw:oCol( "Ürün No" ) )
        oCol:nWidth := 150
        oCol:nDataStrAlign := AL_LEFT
        oCol:nHeadStrAlign := AL_LEFT
        oCol:nEditType        := EDIT_LISTBOX
    oCol:aEditListBound   := TD_UrunNoSec[1]
    oCol:aEditListTxt     := TD_UrunNoSec[2]
    endif


  oBrw:bPopUp := {|o|TD_PopUp(oBrw, o)}
  oBrw:nStretchCol    := STRETCHCOL_WIDEST
    oBrw:lHScroll        := .F.        
    oBrw:lRecordSelector := .f.
    oBrw:lFooter := .T.

    ADD TO oBrw AT 1 DATA oBrw:KeyNo() HEADER 'No' PICTURE '9999'

    oBrw:CreateFromCode()   
 

There is not any code to reset oBrw variable. When I click button in Ürün No variable, it displays the items. but when i choose one of them, it gives an error.
