<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">

<script>
function insertRecord(grid) {
var store = grid.store,
row = store.indexOf(store.insert(0, { Record_Name: "" })[0]);
Ext.defer(function () {
grid.editingPlugin.startEditByPosition({ row: row, column: 0 });
}, 100);
}
</script>
