I used what you suggested to initialize the value to the Session variable and it works great. However, I wanted the form to go to another form upon updating the value so I put a Server.Transfer command into the TextBox_Changed event. It switches just fine but when I put in code to save the Session variable just before the transfer, it doesn't get saved...ie...

private void TextBox_TextChanged(...)
{
Session["helloname"] = TextBox.Text;
Server.Transfer("Form2.aspx");
}

When I step through the code, apparently the Text value hasn't been updated yet, because it's still empty. I know I could do it by adding another object like an OK button and assign the variable there, but is there a way to do it without adding another object?
