Hi Dmitry

What I usually do (pseudo-code):

procedure form.load
thisForm.oFilter = create('empty')

procedure form.filterSet
lparameters filterCriterium, filterValue
addproperty(this.oFilter, filterCriterium, filterValue)
cFilter = '.T.'
for each filterCriterium in this.oFilter
  uFilter = eval('this.oFilter.' + m.filterCriterium)
  cFilter = m.cFilter +iif(isnull(m.uFilter);
   , '';
   , ' and ' + m.filterCriterium + ' = ' + cLitteral(m.uFilter); && cLitteral() makes a litteral out of any value - tell me if you need it
   )
endfor
set filter to &cFilter in this.grid.recordSource

procedure grid.init
for each column in this
  addproperty(header, oFilterCntl, <filter control such as texbox>)
  addproperty(this.oFilterCntl, <filter criterium>, .null.)
endfor

procedure header.click
this.oFilterCntl.visible = .T.

procedure oFilterCntl.Valid
thisForm.filterSet(this.filterCriterium, this.Value)

>When a desktop application window with a grid is open, for example, List of Parts, user can click on the header of any column and make this a searchable column. The index tag is then set to the clicked column field and user can start typing into a Search text box. Where the program dynamically shows/looks for just the items matching the entry.
