Hi Cathi,

Thanks for your answer, but Iam not sure what creating an instance of the page means in this situation. Aren't there already instances of the page there? What would the C# code be to do what you suggested and where should it be placed? It might help you to know that I am calling the SelectedIndexChanged event which places the values for the selection in Session Variables in the dropdown which is an asp dropdown list control. It is set to AutoPostback = True. After it posts I need the other page in the frameset to repost - which causes it to see the new session variables and react accordingly.

Right now if I make a choice from the dropdown it does the server side code and updates the Session Variables. If I push an html button right afterwords its onclick excutes the following javascript that is located in the same page:
function RefreshMain()
{
top.main.location.href='CustMain.aspx';
}

This makes the other page refresh - but I don't want the user having to select the choice and then push the button. It would be nice if the choice from the dropdown would do both.

I am not very advanced at the specifics yet. Thanks again in advance for all your help. Your presentations at Whilfest were very helpful.
