//控件数据绑定 private void btn_serachData_Click(object sender, EventArgs e) { string strValue = txt_sql.Text.Trim(); if (!string.IsNullOrWhiteSpace(strValue)) { //获取数据源绑定DataSet dataSet1 = Helpers.DBHelper.GetDataBySql(strValue); if (Helpers.UtilityHelper.GetRowCount(dataSet1) > 0) { //绑定DataGridView dataGridView1.DataSource = dataSet1.Tables[0]; //绑定BindingSource bindingSource1.DataSource = dataSet1; bindingSource1.DataMember = dataSet1.Tables[0].TableName; //指定数据列绑定TextBox txt_code.DataBindings.Add("Text", bindingSource1, "SITE_CODE"); txt_name.DataBindings.Add("Text", bindingSource1, "SITE_NAME"); //绑定BindingNavigator bindingNavigator1.BindingSource = bindingSource1; } } } //dataGridView数据选择联动 private void textBox1_TextChanged(object sender, EventArgs e) { if (dataGridView1 != null && !string.IsNullOrWhiteSpace(txt_code.Text)) { //切换数据时,定位选中列表行 dataGridView1.ClearSelection(); dataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect; foreach (DataGridViewRow row in dataGridView1.Rows) { string str = row.Cells["SITE_CODE"].Value.ToString(); if (str.Equals(txt_code.Text)) { row.Selected = true; return; } } } }
