i think you should set data source to dgvCmb before adding dgvCmb to datagrid.

Hi,

Try this

C#

<pre lang="HTML">// bind it
dgvCmb.DataSource = a.ToList();

Else 

foreach(var result in a)
{
dgvCmb.items.Add(result);

}

My Datagridview is not connected to the database.
A series of temporary data into a combobox that I will always be in one of his columns, but unfortunately does not show any item
But when the grid is connected to the database combobox that also displays the information correctly

C#

DataGridViewComboBoxColumn dgvCmb = new DataGridViewComboBoxColumn();
dgvCmb.Datasource = dt;//data table
dgvCmb.DisplayMember = "column1";//column to display
dgvCmb.ValueMember = "column2";//id column
dataGridView1.Columns.Add(dgvCmb, "myName");

Happy Coding!
:)
