OleDbConnection con =
new
OleDbConnection(@
"Provider=SQLOLEDB;Data Source=DESKTOP\SQLEXPRESS;User ID=sa; Password = aaa; Initial Catalog=bbb; Integrated secutity=SSPI"
);
DataSet ds =
new
DataSet();
con.Open();
OleDbCommand cmd =
new
OleDbCommand((
"Select itemcode from Item"
), con);
OleDbDataAdapter da =
new
OleDbDataAdapter();
da.SelectCommand = cmd;
DataTable dt =
new
DataTable();
da.Fill(ds);
dataGridView1.DataSource = ds;
DataGridViewComboBoxColumn ic =
new
DataGridViewComboBoxColumn();
ic.HeaderText =
"ItemCode"
;
ic.Name =
"ItemCode"
;
ic.MaxDropDownItems = 6;
ic.DataSource = ds.Tables[0];
ic.DisplayMember =
"ItemCode"
;
dataGridView1.Columns.Insert(1, ic);
this
.dataGridView1.EditingControlShowing +=
new
DataGridViewEditingControlShowingEventHandler(dataGridView1_EditingControlShowing);
con.Close();
}
private
void
editGridCellComboBox_SelectedIndexChanged(
object
sender, EventArgs e)
{
if
(editGridCellComboBox.SelectedItem !=
null
)
{
ComboBox cb = (ComboBox)sender;
int
result = ((ComboBox)sender).SelectedIndex;
editGridCellComboBox.SelectedIndexChanged -= editGridCellComboBox_SelectedIndexChanged;
if
(cb.SelectedItem ==
null
)
return
;
//if (dataGridView1.Columns[dataGridView1.CurrentCell.ColumnIndex].Name = "Itemcode")
//{
// string Description = ((DataRowView)editGridCellComboBox.SelectedItem).Row["Itemcode"].ToString(); **not able to get selected value
//}
//DataRow row = (dataGridView1.CurrentRow.DataBoundItem as DataRowView).Row;
//String val = (String)(cb.SelectedItem as DataRowView).Row("description"); ***this logic also not working
