Response.Write versus output.Write-render method

[silentthread]

Hi,

What is the difference between response.writing a control onto a page, versus creating a WCC that has a render method, and doing something like this....

Protected Overrides Sub Render(ByVal output As System.Web.UI.HtmlTextWriter)
 
        output.WriteBeginTag("input type = 'button'")
        output.WriteAttribute("value", "close me")
        output.WriteAttribute("onclick", "javascript: closeme();")
        output.WriteEndTag("input")
 
    End Sub
