I have a cascadingdropdown extender to which I need to get the selected index. HOwever, selectedindex is not a property of the cascadingdropdown. It will allow the selectedvalue, but I need the selectedindex.

Are you trying to get this from the VB.Net code, or JavaScript?  You have put this in both AJAX and .Net channels so I am unsure which one you are asking for....  Also if you are talking about JavaScript, please let us know if your using the Microsoft AJAX tools build into .Net or XML tools in JavaScript...

Thanks

As far as I know the selected index is not a property or extended in the framework, you could extend the control to make a custom control for this but its a pain, just curious, why don't you use a dropdownlist?  Why do you need to index, what does that give you over the selected value?

You can't get the value from a dropdownlist when it is tied to the cascadingdropdown extender. If you try, you just get a 0 value. so you have to get it from the cascading dropdown. if I ask it for selectedvalue, then it gives me the index, plus the value, such as "1..text value, and i just need the "1", not the text, so I can reference it in my database as a number only.
