Panel Control Add Making Round Trip to Server?

NewbQ:

I am populating a dynamic panel with content. I have multiple panels on a page, so the goal is for the one panel to reload content rather than a reload of the entire page of panels. Looks like every click is making a round trip to the server . . . is this what should be happening or should it be changing the div content client side?

Here's what I have:

void Button1_Click(object sender, EventArgs e) {
 ((Control)((Control)sender).Parent).Controls.Add(new LiteralControl(htmlContentVar));
}

Thanks!

SJonesIn this case, you are going to be doing a round trip to the server.

Thanks for confirming . . .

Any suggestions on a better way to do this using a web control? Is a straight iframe the only/best way?
