Grid column headers have no ID, your getElementById is probably looking at a filter field on the right.Column headers have a "colname" property you can use to get the right element.You can set the text of a column header using this example:$("td[colname=oppo_assigneduserid]").text("abcd");
Thanks so much John! This is a bit embarrassing, but when I did a View Source to examine the HTML, I searched for the text of my column header. My searched returned a result, but what I didn't realize is that the result returned was for the field in the SearchBox - i.e. the panel at the top of the form, not the col header in the Grid at the bottom of the form. If only I had hit FIND NEXT. Oh well, as I say, I greatly appreciate your help!
