如何將數據綁定到數據源？

Question

我得到了1行3列（日期，時間，什麼）的表，我想在我的數據源中的3列（時間，什麼）中的2我該怎麼做？

var table = (from r in socialEvents.AsEnumerable() 
         where r.Field<DateTime>("Date") >= Calendar1.SelectedDate.Date && 
           r.Field<DateTime>("Date") <= Calendar1.SelectedDate.AddDays(1) 
         select r).CopyToDataTable();  

    if (table.Rows.Count > 0) 
       { 
        DataGrid1.Visible = true; 
        DataGrid1.DataSource = table; 
        DataGrid1.DataBind(); 
       } 

Answer 1

我假設datagrid是一個GridView？ 那麼你應該做這樣的事情

<asp:GridView runat="server" AutoGenerateColumns="false" > 
<Columns> 
    <asp:BoundField DataField="what" HeaderText="what" /> 
    <asp:BoundField DataField="time" HeaderText="time" />   
</Columns> 

</asp:GridView>

您可以在選擇

var table = (from r in socialEvents.AsEnumerable() 
         where r.Field<DateTime>("Date") >= Calendar1.SelectedDate.Date && 
           r.Field<DateTime>("Date") <= Calendar1.SelectedDate.AddDays(1) 
         select new {time = r.Field<DateTime>("Date"), what = r.Field<data_type>("what") });
