If it's in the code-behind, it automatically runs at the server.

Instancing any server control in
code-behind makes it run server-side.

 

[Peter Rilling]

Runat is only used by ASP.NET to indicate static tags that will be mapped to
variables in the code-behind. If you dynamically create those controls,
then you have to initialize the controls on each postback. You have to do
this manually when the form initializes.

You don't need to add runat="server" to a dynamically-created control. LinkButton
extends System.Web.UI.Control, so it's already understood by ASP.NET as being
a server-side control (as opposed to client-side controls like <INPUT type="submit">
buttons that have no existence on the server.)

runat="server" is something written in the .ASPX file, if you had created this LinkButton
statically in that file (in what perhaps is confusingly called the "HTML View" although it
is not) you would've written,

<asp:LinkButton ID="Link1" Text="Link Button" runat="server"></asp:LinkButton>

Go and do that and then run the web application in your browser, and do a View Source.
You should never see runat="server" in the HTML.
