我必须为登录用户显示网格视图，比如我的经理，我已经为它编写了存储过程和后端代码，一切看起来都很好，但是网格视图没有被填充，请帮助我
网格视图的后端代码
public DataSet GetManager(MTMSDTO M)
{
DBAccess db = new DBAccess();
SqlParameter objParam = new SqlParameter("@EmpName", M.EmpName);
objParam.Direction = ParameterDirection.Input;
objParam.Size = 50;
db.Parameters.Add(objParam);
return db.ExecuteDataSet("GetManager");
}
public DataSet GetManager(MTMSDTO M)
{
MTMSAccess obj = new MTMSAccess();
return obj.GetManager(M);
}
protected void Page_Load(object sender, EventArgs e)
{
MTMSDTO objc = new MTMSDTO();
if (!IsPostBack)
{
GrdManager();
}
}
protected void GrdManager()
{
MTMSDTO objc = new MTMSDTO();
{
objc.EmpName = Convert.ToString(Session["EmpName"]);
DataSet GrdMA = obj.GetManager(objc);
DataView GrdMan = new DataView();
GrdMan.Table = GrdMA.Tables[0];
GridViewTTlist.DataSource = GrdMan;
GridViewTTlist.DataBind();
}
}
这是我的存储过程
ALTER PROCEDURE [dbo].[GetManager]
@EmpName nvarchar(50)
AS
Select TaskName, DueDate, Description, AssignBy, AssignTo, Status, PercentageComplete
From dbo.Task, dbo.EmployeeData
Where AssignTo in (Select EmpName From EmployeeData Where Manager = 'RaghavendraS')
And AssignBy in (Select EmpName From EmployeeData Where Manager = 'RaghavendraS')
And EmpName = @EmpName;
