Hi there,...
To try and help,.. say you want to requery on the change of a select box value...
In your HTML you change your select box to something like this
Code:
<select name="selName" id="selName" onchange="document.form.submit();">
<option value="1">....etc...,</option>
...etc ...
</select>
This will submit your form when the value changes.....
So basically you have to submit.... but you can use something other then a button to do your submit if you use javascript to trigger it.
Does that help??
