Multi Row Form and onload

Question

Hi,
I've a wizard based Multi Row Form (MRF) based on a view (on 2 tables) with Instead of triggers to handle the DML. I have an onchange event on one particular Select List based item in each row that simply disables/enables other row items depending on the value. All this is working fine, but I need to repeat the disable/enable of items for each row once the page has loaded.
My initial thought is to use an onload event in the Page definition, but can and should I be handling this in a Page Process instead (bear in mind that this is a wizard generated MRF)? Also, I need to ensure that new rows (via the Add Row button) are handled correctly. If I go down the onload event route, then is the simplest way just to get an array (getElementsById?) of the items and loop through them? Any thoughts would be most appreciated on the most efficient way to do this.
Cheers,

Hi,
Yes, it appears the same as an onload but, fortunately, doesn't interfere with any existing onload code - you can only have one onload function call for the window object.
You can loop through the items on the form using something like:
function disableItems()
var x = document.getElementsByName("f03");
var y = document.getElementsByName("f04");
for (int k = 0; k < x.length; k++)
if (x(k).value == 'A')
  y(k).disabled = true;
else
  y(k).disabled = false;
}This assumes that the select list is in column 3 (which should mean that the SELECT objects should have a name attribute of "f03") and that the item you want to disable/enable is in column 4 ("f04") - so adjust as necessary.
As you have the same number of items in column 3 and column 4 - the above loops through the ones in column 3, checks the value selected and then disables/enables the item in the same row in column 4.
