I drag and drop a Table (which I added by "Data Source Configuration Wizard" ) on the
form .as you know visual studio create TableAdapter,DataSet ,..and adds some code automatically .
but when I delete a row and want to save it gives error :
<<update requires="" a="" valid="" deletecommand="" when="" passed="" datarow="" collection="" with="" deleted="" rows.="">>

private void nameBindingNavigatorSaveItem_Click(object sender, EventArgs e)
        {
            this.Validate();
            this.nameBindingSource.EndEdit();
            this.tableAdapterManager.UpdateAll(this.dtDataSet);//Error occurs here 

        }
