Hi!

I have ha promblem with adding items to a DataGridViewComboBoxCell. This is what I am doing.

private void SetUpforDataGridView()

        {

            dataGridViewSearched.ColumnCount = 5;

            dataGridViewSearched.ColumnHeadersDefaultCellStyle.BackColor = Color.Navy;

            dataGridViewSearched.ColumnHeadersDefaultCellStyle.ForeColor = Color.White;

            dataGridViewSearched.ColumnHeadersDefaultCellStyle.Font =

                new Font(dataGridViewSearched.Font, FontStyle.Bold);



            dataGridViewSearched.Name = "Users Searched";

            dataGridViewSearched.AutoSizeRowsMode =

            DataGridViewAutoSizeRowsMode.DisplayedCellsExceptHeaders;

            dataGridViewSearched.ColumnHeadersBorderStyle =

                DataGridViewHeaderBorderStyle.Single;

            dataGridViewSearched.CellBorderStyle = DataGridViewCellBorderStyle.Single;

            dataGridViewSearched.GridColor = Color.Black;

            dataGridViewSearched.RowHeadersVisible = false;

            dataGridViewSearched.Dock = DockStyle.Fill;



            DataGridViewComboBoxColumn dataGridViewcombobox = new DataGridViewComboBoxColumn();

            dataGridViewSearched.Columns.Add(dataGridViewcombobox);



            dataGridViewSearched.Columns[0].Name = "UserId";

            dataGridViewSearched.Columns[1].Name = "Förnamn";

            dataGridViewSearched.Columns[2].Name = "Efternamn";

            dataGridViewSearched.Columns[3].Name = "Legitimation";

            dataGridViewSearched.Columns[4].Name = "Yrkesroll";

            dataGridViewSearched.Columns[5].Name = "Enheter";

            dataGridViewSearched.Columns[5].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;



            dataGridViewSearched.Columns[0].Visible = false;

            dataGridViewSearched.Columns[0].DefaultCellStyle.Font =

            new Font(dataGridViewSearched.DefaultCellStyle.Font, FontStyle.Italic);



            dataGridViewSearched.SelectionMode =

                DataGridViewSelectionMode.FullRowSelect;

            dataGridViewSearched.MultiSelect = false;

        }

And the I am trying to set the table with an object it works fine with the text propertis but not with the DataGridViewComboBoxCell.

        public void BindUserList(List<User> userList)

        {

            dataGridViewSearched.Rows.Clear();

            object[] row = new object[5];

            

            

            foreach (User p in userList)

            {

                row[0] = p.UserId;

                row[1] = p.FirstName;

                row[2] = p.LastName;

                row[3] = p.MedicalProfession;

                row[4] = p.ProfessionalRole;

              

                dataGridViewSearched.Rows.Add(row);

                

                foreach (var unit in p.UnitActivationPeriods)

                {

                    ((DataGridViewComboBoxCell)dataGridViewSearched.Rows[dataGridViewSearched.Rows.Count - 1].Cells[5]).Items.Add(unit.ToString());

                }

                dataGridViewSearched.Rows[dataGridViewSearched.Rows.Count - 1].Tag = p;



            }

            labelNumberOfUsers.Text = userList.Count.ToString();

            dataGridViewSearched.Refresh();

        }

Thanks, Mjelten

Hi! My code works fine...I just had to change the property of the datagrid to readonly = false;

If I understand your code correctly, you are trying to add rows to the combobox for each row in the grid?

The DataGridView combobox column by default is set up to have *ONE* list of items. Each row can then have a value from that list.

So for example, you could populate the combobox column with a set of customer types. Then each row would have *one* customer type selected from that list of customer types.

Hope this helps.

Ok, so if I understand you correctly I cannot have different values in each combobox?

|TEXTColumn| |TEXTColumn | |TEXTColumn |DataGridViewComboBoxColumn |
|John | |Svensson | |1231421 |Cat |
| | || | |Dog |
| | || | |mouse|
|Sarndra | |Larsson | |2344324 |Horse |
| | | | | |Bird |
|Adam | |Jönsson | |6587568 |dog |
| | || | |Horse |
| | || | |badger |
| | || | |Tiger |

This is what I want to achieve.
