Combobox C#,用DataTable填充,但在我的数据库中选择了ID。
我的表是PRODUTO,ID为PRODUTO.PRO_LOCAL 表LOCAL: 1 - 萨帕托斯 2 - Roupas 3 - Acessórios
PRODUTO.PRO_LOCAL = 2,但我的组合框填充顶部LOCAL = 1,这是查询中的第一个。
填充组合框的DataTable:
angular.module('MyApp')
.config(function($mdThemingProvider, $mdIconProvider){
$mdIconProvider
.defaultIconSet('img/icons/sets/core-icons.svg', 24);
$mdThemingProvider.theme('default')
.primaryPalette('red')
.accentPalette('red');
})
.controller('ListCtrl', function($scope, $mdDialog) {
$scope.accounts = [
{id: 1, title: "Account A", selected: false},
{id: 2, title: "Account B", selected: false},
{id: 3, title: "Account C", selected: false},
];
...
Form FrmProduto中的Combobox:
public DataTable RetornaLocal()
{
SqlConnection sqlConnection = acessoDadosSqlServer.CriarConexao();
sqlConnection.Open();
SqlCommand sqlCommand = sqlConnection.CreateCommand();
sqlCommand.CommandText = "SELECT loc_cod, loc_descricao FROM local ORDER BY loc_descricao";
SqlDataReader sqlDataReader = null;
sqlDataReader = sqlCommand.ExecuteReader();
DataTable dataTable = new DataTable();
dataTable.Load(sqlDataReader);
return dataTable;
}
我希望FrmProduto在更改模式下显示表PRODUTO的ID而不是查询返回LOCAL规范
答案 0 :(得分:0)
设置了SelectedValue - > produto.pro_local字段。 怎么做:
cbLocal.DisplayMember = "loc_descricao";
cbLocal.ValueMember = "loc_cod";
cbLocal.DataSource = localNegocios.RetornaLocal();
cbLocal.SelectedValue = produto.pro_local ;
