I found that you can cause the page to generate the autopostback script with a call to Page.ClientScript.GetPostBackEventReference(). If you wrap your conditional logic around the postback event reference you end up with cleaner conditional postback code. In fact, it boils down to one line you can put in your control code behind. DropDownList1.Attributes.Add("onchange", "if(this.selectedIndex==2){"+Page.ClientScript.GetPostBackEventReference(DropDownList1, "")+"} return true;" ); Enjoy!

Any help is greatly appreciated. b r e n t I’m just using ISAPI for the first time to rewrite my .html urls to .php

Here’s something I found that works with apache using mod_rewrite:

# Redirects .html to .php
Options +FollowSymLinks
RewriteEngine on
RewriteRule ^(.*).html$ $1.php [QSA,L]

I do understand regex somewhat, but I don’t really know what the QSA,L means, does anyone know how to rewrite this for ISAPI? Any help is greatly appreciated.

RewriteRule /([^?/]+)/popular/?\??(.*) /$1/default.aspx?page=PopularItems&$2 [I,L] The sample above uses virtual directory. This is the same sample without virtual directory: RewriteRule /popular/?\??(.*) /default.aspx?page=PopularItems&$1 [I,L] Is this what you are looking for?

RewriteRule /([^?/]+)/popular/?\??(.*) /$1/default.aspx?page=PopularItems&$2 [I,L]

The sample above uses virtual directory. This is the same sample without virtual directory:

RewriteRule /popular/?\??(.*) /default.aspx?page=PopularItems&$1 [I,L]

So when you define a function like: String.prototype.trim = function(){ } Then you can just use it like: test.trim() While not being very spectucular, it’s still pretty neat. When you are dealing with forms that require a lot of checks, than this baby can come to hand. Here the blog entry that pointed me to this.
