Question

can i send a server control from the aspx.cs page

Answer 1

If by “send” you mean “create”, then you can do it easily by adding the dynamically created control to a container such as the Page or a Panel:

LinkButton lnk1 = new LinkButton();
// Set any required properties.
...

// Add the control to the container.
Panel1.Controls.Add(lnk1);

The LinkButton will be rendered at the client as expected.
