Auto refreshing a datagrid!

hi,

I want to auto refresh a datagrid alone.
I placed the datagrid inside a <Div> tag so that I can write a javascript to refresh the datagrid. The div is not refreshed please tell me what I can do :confused: ????????

function RefreshDiv() {
var szdiv
szdiv=window.document.getElementById("divID");
szdiv.refresh();
}

This is an ASP.NET question so it should be in the ASP.NET forum.
