When is it safe to disable viewstate?

When is it safe to disable viewstate? For control? In what circles?

In a user control, I disabled viewstate, but if I try to click this control

<asp:LinkButton ID="LinkButton1" runat="server" 
  CommandName="Delete" 
  OnClientClick="return confirm('¿Está seguro que desea eliminar el mensaje?');"
  EnableViewState="true">
    <asp:Image ID="ImageButton1" runat="server" ImageUrl="~/Content/Images/delete.png" 
        ToolTip="Eliminar mensaje" /> Eliminar 
</asp:LinkButton>

I get a System.InvalidOperationException exception. It is inside the ListView.

Most controls behave as you would expect with a viewstate disabled. More “dynamic” controls with built-in features like Gridview tend to not play well without a viewstate.

If you are using .net framework 2.0 or a later version of the framework, you can use a new function called control state, not view state. This is much faster in terms of performance compared to performance.
