default selected value in DHTMLX combo with Filtering enable

Im using DHTMLX combo version 1.5 with Filtering enabled

“cmbModule.enableFilteringMode(true);”.



How can I make a particular value from the List of options as SELECTED on load of the combo.



I have tried “cmbModule.selectedIndex = 6”, but not working. Is there any way to achieve this?

combo.loadXML(url,function(){
combo.selectOption(6,false,true);
//or if you need to select it by value - combo.setComboValue(value);
});
