Hi Niloofar,

It looks like you are missing adding your cached id  value to the RadComboBox. 

Try changing this code:
for (int i = itemOffset; i < endOffset; i++)
{
    (o as RadComboBox).Items.Add(new RadComboBoxItem(rows[i]["title"].ToString()));
}

to this:
for (int i = itemOffset; i < endOffset; i++)
{
    (o as RadComboBox).Items.Add(new RadComboBoxItem(
        rows[i]["title"].ToString(),
        rows[i]["id"].ToString() ));
}

Hope that helps,
Thad
