我在表单的事件处理程序中添加了一个DataGridViewComboBoxColumna DataGridView,Load并DataGridViewComboBoxCell在列中设置了每个的DataSource .但是,一旦显示表单,每个的DataSource DataGridViewComboBoxCell都已设置为null.这是我用来填充列及其单元格的代码:

DataGridViewComboBoxColumn comboCol;

comboCol = new DataGridViewComboBoxColumn();
comboCol.Name = "ComboCol";
comboCol.HeaderText = "Combo Column";
comboCol.AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;

this.dgv.Columns.Add(comboCol);

for (int i = 0; i < dgv.Rows.Count; i++)
{
    // This datatable is actually populated here!
    DataTable myData = PopulatedDataTable(dgv.Rows[i].Cells["info"].Value); 

    DataGridViewComboBoxCell DCC = new DataGridViewComboBoxCell();

    DCC = (DataGridViewComboBoxCell)dgv.Rows[i].Cells["CombolCol"];
    DCC.DataSource = myData;

    DCC.DisplayMember = "Association"; // Association is a column in myData
    DCC.ValueMember = "Association";
}

dgv.Columns["association"].Visible = false; …
