One easy solution is to register some JavaScript code in your page:

string script = "alert(\"Hello!\");";

ScriptManager.RegisterStartupScript(this, GetType(),ServerControlScript", script, true);

Use:

string display = "Pop-up!";

ClientScript.RegisterStartupScript(this.GetType(), "yourMessage", "alert('" + display + "');", true);
