select new{ c.fName,c.lastName,c.title,c.accountName,c.officePhone,c.assignTo};
GridView1.DataSource = getAllContacts;
GridView1.DataBind();

bindGrid();
}
}
protected void deleteContact_Click(object sender, EventArgs e)
{
for (int i = 0; i
{
CheckBox cb=(CheckBox)GridView1.Rows[i].Cells[0].FindControl("CheckBox1");
if ((cb != null)&&(cb.Checked))
{
var getAllContacts = from c in dcon.contact_contactInfos
select new { c.cid };
foreach (var item in getAllContacts)
{
var deleteContactAddress = con.contact_contactInfos.Single(contact =>contact.cid == item.cid);
dcon.contact_contactInfos.DeleteOnSubmit(deleteContactAddress);
dcon.SubmitChanges();
bindGrid();
