Display Insert Template on FormView when "Add New" button is clicked

    I'm fairly new to working with ASP web controls, and am running into
    what seems to be a ridiculous problem that I'm hoping will be a breeze
    for an experienced ASP developer.

    I have a GridView and a FormView on the same page, where the GridView
    is visible at page load, and the FormView is set to Edit mode by
    default, but is hidden on the page. I have the Select link enabled on
    my GridView, and I use the SelectedIndexChanged event to hide the
    GridView, update the SelectCommand on my datasource with the
    SelectedIndex, and finally show the FormView. This all works
    beautifully, and I get my FormView populated with the data from the
    selected Index shown on the page.

    The code to handle this is fairly simple, and looks like the following:
    (with the bulk of the query removed for readability)

    protected void GridView1_SelectedIndexChanged(object sender, EventArgs
    GridView1.Visible = false;
    FormView1.Visible = true;
    dsPackageEdit.SelectCommand = "SELECT ... WHERE [ID] ="

    I want to do the essentially the same task for an Insert template as
    well, which seems like it would be even less work to accomplish. The
    InsertCommand is already defined, so essentially I want to just set the
    mode to Insert, hide the GridView, and show the FormView. My resulting
    attempt at this looks like the following:

    protected void LinkButton1_Click(object sender, EventArgs e)
    GridView1.Visible = false;
    LinkButton1.Visible = false;
    FormView1.Visible = true;


    However, in practice, the first 3 commands execute fine, and both the
    GridView and the button are hidden, and the mode on the FormView is
    indeed changed to Insert, but the line to display the FormView again is
    not successful, and I end up with essentially a blank page.

    I've scratched my head on this for a while, seeing as I have 2
    functions performing essentially the same task, where in one
    FormView.visible = true works perfectly, but in the other, it does not.
    Is there a reason why this would behave the way it is? Or is there
    perhaps a more graceful way to approach this entire situation?

    Your time and assistance is greatly appreciated.

    I'm still a little confused over this occurrence. I've looked into it
    in every way possible, but I'm apparently overlooking something. Any
    assistance would be very much appreciated.
