Hey

If I understood your question, are you asking to rebind the data after being saved?

You can use two way binding or if you are using SqlDataAdapter to fill the combobox then just you need to fill the dataTable again to reflect changes.

public DataTable GetTable(String sql)
{
DataTable dt = new DataTable();
try
{
SqlDataAdapter da = new SqlDataAdapter(sql, con);
da.Fill(dt);
return dt;
}
catch
{
return dt;
}
}

//For Fill Combobox With Database Values
public void FillCombo(ComboBox cb, string sql, string DisplayField, string ValueField)
{
DataTable dt = new DataTable();
dt = GetDataTable(sql);
cb.DisplayMember = DisplayField;
cb.ValueMember = ValueField;
cb.DataSource = dt;
}

Use:
fillcombo(Combobox2,"select * from emp","Name","Name");
