As the error message says, you cannot get data from a deleted row. You need to ignore deleted rows when repopulating your control:

Code:

---

LstSettingsUserResult.BeginUpdate();
foreach (DataRow drUserAccount in dsSearchResult.Tables[0].Rows)
{
    if (drUserAccount.RowState != DataRowState.Deleted)
    {
        LstSettingsUserResult.Items.Add(drUserAccount["User_LoginName"].ToString());
    }
}
LstSettingsUserResult.EndUpdate();

---

That said, wouldn't you be better off just binding this table to the control, in which case the item will be automatically removed from the control when you delete the row?

Oh....Nice suggestion, I'll try that JM...But expect some follow-up question. :D Thanks a lot anyway.

can you help me to bind the listbox from my binding source? I have tried the code below but i have no luck..

Code:

---

bsSearchResult.DataSource = dsSearchResult.Tables[0];
            LstSettingsUserResult.DataBindings.Add("Items", bsSearchResult, "User_loginName");

---

ERROR:

Quote:

---

Cannot bind to property 'Items' because it is read-only.
Parameter name: PropertyName

---

You use the DataSource, DisplayMember and ValueMember properties, just like a ComboBox.

Ok...Thanks a lot!
