Simply add new comboBox Cell in every row

C#

DataGridViewComboBoxCell dgvCmbCell;
dgvCmbCell = (DataGridViewComboBoxCell)myGrid.Rows[rowInx].Cells[colInx];
dgvCmbCell.Items.Clear();
dgvCmbCell.Value = null;
//And make your loop 
while (...)
{
    dgvCmbCell.Items.Add(.....);
}

I believe it will reach your requirement;

Solution 1

how about add first the row then update the items in the ComboBoxColumn

VB

Dim dtgCol As DataGridViewComboBoxCell
Dim row As String()

row = New String() {"0", "1"}
dtgView.Rows.Add(row)

dtgCol = dtgView.Rows(0).Cells(2)
dtgCol.Items.Add("comboitem1")
dtgCol.Items.Add("comboitem2")

row = New String() {"2", "3"}
dtgView.Rows.Add(row)

dtgCol = dtgView.Rows(0).Cells(2)
dtgCol.Items.Add("comboitem1")
dtgCol.Items.Add("comboitem2")
dtgCol.Items.Add("comboitem3")

this is just my idea.. I already done this... hope this helps

No row can be added to a DataGridView control that does not have columns. Columns must be added first.

Its Showing above error

I don't know if this will answer your question...

Dim cmbCol As New DataGridViewComboBoxColumn()
cmbCol.HeaderText = "ColName"
dtgView.Columns.Add(cmbCol)

That will add column combobox in grid
