clickable column

This code below makes Name column in my grid all clickable and redirects, but what I need is only when loginPassword is null and ((bool)Session["Account"] == true)
I tried to put that in MakeLInk code below and I added this code but it only makes one row clickable even though I have two null password rows(records)
protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item.ItemType == GridItemType.AlternatingItem ||
            e.Item.ItemType == GridItemType.Item)
        {

            Password = DataBinder.Eval(e.Item.DataItem, "loginPassword").ToString();

            GridDataItem dataItem = (GridDataItem)e.Item;

            if (Password == "")

                SetPassword = "";
           
        }  
    }
