You'll want to grab the Parent of the ImageButton and the find the lblMsg control.

An example of this in C# is

void BtnSubmit_click(object sender, EventArgs e)
{
  // This gets the image button that fired
  ImageButton SubmitButton = (ImageButton)sender;
  // Get the parent container and find the lblMsg control
  Label lblMsg = (Label)SubmitButton.Parent.FindControl("lblMsg");

  // Set the value of lblMsg to what you want
  lblMsg.Text = "My updated Status";
}

If this isn't what you are looking for, please provide other details.
