Calling a VB.NET function from JavaScript

Calling a VB.NET function from JavaScript

Is this possible?

I need to re-populate the controls of a parent window, when a child window is closed. I planned to do this by simply calling my PopulateControls() method in the parent's code behind, but am beginning to believe this is not possible?

If so, is there a workaround?
Thanks.

You'd be right, it's not possible. You'd have to reload the page to get vb.net to execute. If you need to load things on the parent page that are dependent on what the user selected in the popup, you can pass a parameter in the url.

opener.location.href="parentPage.aspx?popupParam=" + document.formName.fieldName.value

Thanks adam. That's a useful suggestion. It might be a little more complicated than that as the page is part of a multipage wizard and the control I want to populate is actually a datagrid.....

Will keep working on it.

Thanks again.

In short, you can't call server-side functions from the client, but you CAN manipulate parameters/fields and trigger PostBacks/ wire client events to trigger Server Control's event handlers (via Page.GetPostBackEventReference).

VS 2005 will change this so you CAN use client callbacks.
