Updating Portlet content in DirectMethod
Hi, I have a portlet on a page and I have a user control inside the portlet.
I hooked up the click event of Gear tool of portlet with a DirectMethod.
In direct method I am changing the content of UserControl and I want the updates to show up in the browser without refreshing the whole page.
I tried Render(), Update() and UpdateContent() methods on the portlet. None of them is working.
Any idea how I can achieve this. Please see the attached code:

uc.ID = "myUC";
Portlet p = new Portlet();
p.ContentControls.Add(uc);
p.Padding = 5;
p.Header = true;
portalColumn1.ContentControls.Add(p);
p.Tools.Add(new Tool(ToolType.Gear, "handleEdit();", "Edit"));
}
[DirectMethod]

Portlet p = ControlUtils.FindControls<Portlet>(this)[0];
TestControl tc = (TestControl)p.ContentControls[0];
tc.setName("Test Name");
p.Update();
p.Render();
p.UpdateContent();
}

{
X.Msg.Alert("Status", e.ExtraParams["ID"] + " Hidden").Show();
