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; } } }
