Custom value for select_filter in header

In the select_filter in header, the blank value represents all the values. Instead of displaying it as blank, we i want to display as All.

I have attached a function on XLE. I have two select filters in my header.



function changeOption(gridObj,numOfRows)    {

var opt= gridObj.hdr.getElementsByTagName (“SELECT”);

for(i=0;i<opt.length;i++){

alert(opt[i].innerHTML);

}

}



the innerHtml that alerts is:





SO i cant change text of the first option.

Could you suggest some way?
