Solution 1

Rebind the Gridview like which you have called in Page_Load. Make this code block as generic procedure & call that which places you want such as After Edit, After Delete, After New.

i have created a method named bindGrid() and called it in page load and on delete.

It is all clear that when u have deleted the record that means your collection and database has changed so it is always better to fetch the data again same applies while updating and inserting the records...

C#

protected void bindGrid()
{
var getAllContacts = from c in dcon.contact_contactInfos
select new{ c.fName,c.lastName,c.title,c.accountName,c.officePhone,c.assignTo};
GridView1.DataSource = getAllContacts;
GridView1.DataBind();
}
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
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();
}
}
}
}
