加载带有列表的gridview？答案

【问题描述】：

我有一个列表，其中包含我想在我的 gridview 上显示的所有行。我从数据层上的数据读取器获取这些行，一旦我将列表调用到表示层，我想将列表结果绑定到网格视图。有没有办法做到这一点？代码如下。

数据层查询和数据读取器获取行的所有数据

public class SubmissionDatabaseService
{
    public List<Submission> GetAllSubmissions()
    {
        string Searchstring = "SELECT Submission.SubmissionId, Customer.CustName, Customer.CustCity, Customer.CustState, Broker.BroName, Broker.BroState, Broker.EntityType, Submission.Coverage, Status.Status FROM Submission INNER JOIN Broker ON Broker.BroId = Submission.BroId INNER JOIN Customer ON Customer.CustId = Submission.CustId INNER JOIN Status ON Status.StatusId = Submission.StatusId";
        string connectionString = System.Configuration.ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString;
        SqlConnection conn = new SqlConnection(connectionString);

        SqlDataReader dr = null;
        List<Submission> lstSubmission = new List<Submission>();

        conn.Open();

        SqlCommand Searchcmd = new SqlCommand(Searchstring, conn);

        dr = Searchcmd.ExecuteReader();

        Submission tempSubmission;
        while (dr.Read())
        {
            tempSubmission = new Submission();
            tempSubmission.setSubmissionId(dr.GetInt32(0));
            tempSubmission._Cust.setCustName(dr.GetString(1));
            tempSubmission._Cust.setCustCity(dr.GetString(2));
            tempSubmission._Cust.setCustState(dr.GetString(3));
            tempSubmission._Bro.setBroName(dr.GetString(4));
            tempSubmission._Bro.setBroState(dr.GetString(5));
            tempSubmission._Bro.setEntity(dr.GetString(6));
            tempSubmission._SubCov.setCoverage(dr.GetInt32(7));
            tempSubmission.setStatus(dr.GetString(8));

            lstSubmission.Add(tempSubmission);

        }
        return lstSubmission;
    }
}

业务逻辑层

public class SubmissionService
{
    public SubmissionService() { }

    private Array _getllsubservice;

    public Array Getallsubservice
    {
        get { return _getllsubservice; }
        set { _getllsubservice = value; }
    }

    public List<Submission> getAllSubmission()
    {
        SubmissionDatabaseService sds = new SubmissionDatabaseService();
        return sds.GetAllSubmissions();
    }
}

表示层

SubmissionService ss = new SubmissionService();
List<Submission> SubmissionsList = ss.getAllSubmission();`

【问题讨论】：

您只需将数据显示到网格中？
实际上，我还需要它是可排序和可搜索的。我想我会从基本问题开始，然后从那里开始。
如果有帮助别忘了采纳答案！ ;)

【解决方案1】：

要将数据加载到网格视图中，请尝试：

yourgrid.DataSource=SubmissionsList;
yourgrid.DataBind();
