Set SelectedValue in DataGridViewComboBoxColumn or DataGridViewComboBoxCell

Question

I would like to set a value to the ComboBox in the DataGridView. I already have changed the comboBoxItems, I just want to select one of them. Thank you in advance!!!

Answer 1

I already solved my problem... I'm gonna post the way I did and hoppefully someone will find this answer too.

   dgrDetalle.DataSource = dataTable("select * from yourTable");
   DataTable dtCombo = dataTableCombo("select COL_ID DETOC_COL_FK,COL_DESCRIPCION from yourTable2");
   string[] strColumns = new string[] { "COL_DESCRIPCION" };
   MultiColumnDictionary map = new MultiColumnDictionary(dtCombo, "DETOC_COL_FK", strColumns, 0);
   dgrDetalle.Cols["DETOC_COL_FK"].DataMap = map;

As you can see the class that save my life is MultiColumnDictionary.

Note: The combobox items must be loaded in a different DatatTable than the DataTable that is gonna load directly in the grid.

Answer 2

As far as I know, the Comboboxes only actually exist as controls when they are being edited, and therefore don't have a selected item property.
You can simply set the Value property of the cell to the item you want selected, or alternitively, you can set a default value by setting the property:

DataGridViewColumn.DefaultCellStyle.NullValue.
