enableFilteringMode in a grid cell combo

I want to ask the usage of “enableFilteringMode”.

But the combo is a cell in a grid.

How to do this “enableFilteringMode” in a grid cell combo ?



 grdApplyTo = winApplyTo.attachGrid();

  grdApplyTo.setHeader("Parameter Name, Select");
  grdApplyTo.setColumnIds("txtParaName,SELECT");
  grdApplyTo.attachHeader("#select_filter");
  grdApplyTo.setInitWidths("200,100");
  grdApplyTo.setColTypes("combo,ch");
  grdApplyTo.setColSorting("str,str");
  grdApplyTo.enableEditEvents(true, true, true); 
  grdApplyTo.init();

[code]
grid = new dhtmlXGridObject(‘gridbox’);

grid.setColTypes("…,combo,…");
grid.init();

combo = grid.getColumnCombo(columnIndex);

combo.enableFilteingMode(true);
combo.loadXML(“data.xml”);[/code]
