Apologies.
Before I continue. I am just learning ASP.net so let me know if
anything doesn't make sense. I did ASP for 3 years, but that was a good
while ago now and my mind is slowely decaying.
I have listed CLIENT and SERVER Side code below.
0) btnSearch is the button in question I click and no server side
onclick event is fired.
1) See Below
2) See Below
3) See Below
4) See Below
Let me know if you need anything else. Thanks for your help.
John.
