Databind fires after ItemUpdated event
<p>I'm using an asp.net 4 web site project (C#) in VS2008 and I have a FormView with ItemUpdated event:</p>

<pre><code>&lt;asp:FormView ID="FormView1" runat="server" DataSourceID="ds1" OnItemUpdated="FormView1_ItemUpdated"&gt;
    &lt;EditItemTemplate&gt;
        &lt;asp:TextBox ID="TextBox1" runat="server" Text='&lt;%# Bind("col1") %&gt;' /&gt;
    &lt;/EditItemTemplate&gt;
&lt;/asp:FormView&gt;

protected void FormView1_ItemUpdated(object sender, EventArgs e)
{
    FormView1.DataBind();  // adding this line even doesn't help
    TextBox box = FormView1.FindControl("TextBox1") as TextBox;
    box.Enabled = false;
}
</code></pre>

<p>But I can't figure out, why an extra "FormView1.DataBind()" or Render(?) happens AFTER the ItemUpdated event. The result is that my code in the ItemUpdated event gets like "overwritten" and the TextBox1 doesn't get disabled.</p>

<p>When I set a breakpoint to the last line "box.Enabled = false;" then I see that after the ItemUpdated event it jumps to the aspx page again and steps through the TextBoxes.</p>

<p>Disabling this TextBox1 from another GridView1_SelectedIndexChanged works fine.</p>

<p>Is there any way to see the "current lifecycle progress" in debugging?</p>

<p><strong>EDIT:</strong></p>

<p>To clarify the reasoning...
I have a GridView1 where selecting the item populates the abovementioned FormView1. The point is that I need to disable some of the TextBoxes in the FormView1 based on, for example, user access levels. 
Selecting the item from GridView1 disables the TextBox1 just fine, but when I click the Update button on the FormView1 then all TextBoxes are enabled, even if I see in the debugger code running through the GridView1_SelectedIndexChanged() function. And after I re-select the gridview item, the correct TextBoxes are disabled again.
Using even this code:</p>

<pre><code>&lt;asp:FormView ID="FormView1" runat="server" DataSourceID="ds1" DefaultMode="Edit" OnItemUpdated="FormView1_ItemUpdated"&gt;
    &lt;EditItemTemplate&gt;
        &lt;asp:TextBox ID="TextBox1" runat="server" Text='&lt;%# Bind("col1") %&gt;' /&gt;
        &lt;asp:TextBox ID="TextBox2" runat="server" Text='&lt;%# Bind("col2") %&gt;' /&gt;
        &lt;asp:Button ID="Btn1" runat="server" CommandName="Update" Text="Update" /&gt;
    &lt;/EditItemTemplate&gt;
&lt;/asp:FormView&gt;

protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
    if (UserAccess() == false) {
        TextBox box2 = FormView1.FindControl("TextBox2") as TextBox;
        box2.Enabled = false;
    }
}
protected void FormView1_ItemUpdated(object sender, EventArgs e)
{
    GridView1_SelectedIndexChanged(sender, e);
}
</code></pre>

<p>Maybe I should disable my Textboxes via another event?</p>
