Hello,

I'm needed to update the querystring after the user changes the value in the DropDownList.

I think this can be done with javascript, but I can't figure out how to do it!

Thanks for any help!

Hi there,

You can add an attribute to the drop down which can call a javascript function. It is best placed in the page_load event.

dropdown.attributes.add("onChange","MyJavaScriptFunction()")

The function is called every time the selected item is changed.

Thanks for the reply!

Yes, that's actually the part that I know how to do.  It's how to you pass the selected value of the dropdown to the java function that I don't know how to do.  Actually, I'm needing an example of the entire java function.  The function should do the postback --- how do I do the postback with a querystring?

Thanks

BTW, i think the request.querystring is a readonly property. So you have to redirect it to add or change the querystring values...
