datatable绑定comboBox显示数据[C#]

实现功能：datatable绑定comboBox,在下拉菜单中显示对应数据
实现方法：
　　　　//dataSet 转 dataTable
　　　　1、生成datatable，并为combox绑定数据源：comboBox1.DataSource = dt1;comboBox1.DisplayMember = "用户编码";comboBox1.ValueMember = "ID";this.comboBox1.SelectedIndex = -1;2、在combox的SelectedIndexChanged事件中添加如下方法：private void comboBox1_SelectedIndexChanged(object sender, EventArgs e){int iCurrentIndex = this.comboBox1.SelectedIndex;if (iCurrentIndex < 0) return;DataRow dr = dt1.Rows[iCurrentIndex];iID = Int32.Parse(dr["ID"].ToString());}
另：如果textBox也想绑定该数据源，实现连动（如输入编码显示对应名称）3、在textBox的TextChanged事件中添加如下方法：private void textBox1_TextChanged(object sender, EventArgs e){string strUserNo = this.textBox1.Text.Trim();for (int i = 0; i < dt1.Rows.Count; i++){if (dt1.Rows[i]["用户编码"].ToString() == strUserNo){this.comboBox1.SelectedIndex = i;break;}else{this.comboBox1.SelectedIndex = -1;}}}
