如何加载特定值DataGridViewComboBoxColumn

Question

大家好我已经使用DataGridViewComboBoxColumn绑定了我的datagridview，如下所示             dataGridView1.DataSource = db.DT（sql）;

        DataGridViewComboBoxColumn Column1 = new DataGridViewComboBoxColumn();
        Column1.HeaderText = "Status";

        Column1.Name = "Column1";
        DTchequeStatus = db.DT("SELECT [ID] ,[Status] FROM [ChequeStatus]");

        Column1.DisplayMember = "Status";
        Column1.ValueMember = "ID";
        Column1.DataSource = DTchequeStatus;



        foreach (DataRow DR in DTchequeStatus.Rows)
        {

           // Column1.Items.Add(DR["Status"].ToString());
        }
        this.dataGridView1.Columns.Add(Column1);



         dataGridView1.Columns["Column1"].ReadOnly = false;
         foreach (DataGridViewRow DR in dataGridView1.Rows)
         {
             (DR.Cells["Column1"] as DataGridViewComboBoxCell).Value = (int)DR.Cells["Cheque Status"].Value;
         }

但这会导致我的datagridview的空值如下所示。我应该怎么做才能获得一个值 i tried this Why on Initial load DataGridViewComboBoxColumn showing empty value 但不起作用

只需设置

Column1.DataPropertyName = "ID" 

将解决问题
