Id is displayed in DataGridViewComboBoxColumn in DataGridview in windows application in VS 2010

This is a windows Application.
I am using Datagridview.
In the Datagridview i am haivng three DataGridViewComboBoxColumn and one DataGridViewTextBoxColumn.
I have bound the comboboxes and svaing the values.
I am saving Id in the database.
When i fetch and display in the combobox, for first combo alone the id is displayed rather than value.
