为什么我的数据集没有填充我的GridView

Question

我不知道为什么我的数据没有显示在我的gridview中，如果我使用sqldatasource与它的作品相同的查询。

cmd.Connection = conn 
    conn.Open() 
    cmd.CommandText = "SELECT DISTINCT TOP (100) PERCENT dbo.tblConfig_Agent.FirstName, dbo.tblConfig_Agent.LastName, SUM(dbo.tblData_DeviceByDevice.ACDCount) AS Calls, SUM(dbo.tblData_DeviceByDevice.ACDDuration) AS Seconds, dbo.tblConfig_AgentGroup.Name, dbo.tblConfig_Agent.Pkey FROM dbo.tblData_DeviceByDevice INNER JOIN dbo.tblConfig_AgentGroup ON dbo.tblData_DeviceByDevice.FKDevice2 = dbo.tblConfig_AgentGroup.Pkey INNER JOIN dbo.tblConfig_Agent ON dbo.tblData_DeviceByDevice.FKDevice1 = dbo.tblConfig_Agent.Pkey WHERE  (dbo.tblData_DeviceByDevice.MidnightStartDate BETWEEN '4/10/2011' AND GETDATE())GROUP BY dbo.tblConfig_Agent.FirstName, dbo.tblConfig_Agent.LastName, dbo.tblConfig_AgentGroup.Name, dbo.tblConfig_Agent.Pkey ORDER BY Seconds, dbo.tblConfig_Agent.FirstName, dbo.tblConfig_Agent.LastName" 
    da.Fill(ds, "test") 


    GridView2.DataSource = ds.Tables("test") 
    GridView2.DataBind() 
    conn.Close() 
    UpdatePanel1.Update()

我认为你必须检查你的数据集填充方法....

DataAdapter

// Assumes that connection is a valid SqlConnection object. 
string queryString = 
    "SELECT CustomerID, CompanyName FROM dbo.Customers"; 
SqlDataAdapter adapter = new SqlDataAdapter(queryString, connection); 

DataSet customers = new DataSet(); 
adapter.Fill(customers, "Customers");
