xBrowse - incremental search

[Otto]

If I search and the find position is not on the first page I lose the header and the row pointer.

Search the string ::lRefreshOnlyData := .T. (2 times) in the method Seek of txBrowse, coment it.

[Otto]

Thank you.
I have verion 07.11 and I can't find lRefreshOnlyData 2 times in the methode.

Otto,

Use this code:

Code: Select all  Expand view

METHOD Seek( cSeek ) CLASS TXBrowse

   local uBook, uSeek

      if ! Empty( ::cSeek )
         ::cSeek := ""

            ::oSeek:SetText( "" )
         Endif
      endif
      return nil
   Endif

   uBook := Eval( ::bBookMark )

   if !Eval( ::bSeek, cSeek )
      Eval( ::bBookMark, uBook )
      MsgBeep()
      return nil
