combobox 的 datasource 一般是查询存储过程得到 , 但在测试或演示时,也可以自己定义 , 方法是 :
DataTable customerTable = new DataTable(); customerTable.Columns.Add("clsCustomerID", typeof(string)); //定义列类型 customerTable.Columns.Add("clsCustomerNM", typeof(string)); DataRow row = customerTable.NewRow(); //加一行 row["clsCustomerID"] = "01.2136"; row["clsCustomerNM"] = "MAXIS1"; customerTable.Rows.Add(row); DataRow row1 = customerTable.NewRow(); //加另一行 row1["clsCustomerID"] = "01.2255"; row1["clsCustomerNM"] = "VSC2_PRE_W1"; customerTable.Rows.Add(row1); comboBox1.DataSource = customerTable; //设置datasource 和 显示和实际数据列 comboBox1.DisplayMember = "clsCustomerNM"; comboBox1.ValueMember = "clsCustomerID";
