我有一個更新 grid-view 的更新面板，grid-view 連接到 mySql 數(shù)據(jù)源，更新面板的觸發(fā)器是一個計時器，每 1 秒滴答一次。但問題是當(dāng)計時器打勾時，整個頁面都會回傳。任何的想法 ？<asp:ScriptManager ID="ScriptManager1" OnLoad="Timer1_Tick" runat="server" /> <asp:UpdatePanel ID="UpdatePanel1" UpdateMode="Conditional" ChildrenAsTriggers="true" runat="server"> <ContentTemplate> <asp:Timer ID="Timer1" runat="server" Interval="1000" OnTick="Timer1_Tick" Enabled="False"> </asp:Timer> <asp:GridView ID="GridView3" runat="server" AutoGenerateColumns="False" DataKeyNames="ID" DataSourceID="SqlDataSource3"> <Columns> <asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False" ReadOnly="True" SortExpression="ID" /> <asp:BoundField DataField="Sensor1" HeaderText="Sensor1" SortExpression="Sensor1" /> <asp:BoundField DataField="Sensor2" HeaderText="Sensor2" SortExpression="Sensor2" /> <asp:BoundField DataField="Sensor3" HeaderText="Sensor3" SortExpression="Sensor3" /> <asp:BoundField DataField="Sensor4" HeaderText="Sensor4" SortExpression="Sensor4" /> <asp:BoundField DataField="Time" HeaderText="Time" SortExpression="Time" /> </Columns> </asp:GridView> <asp:SqlDataSource ID="SqlDataSource3" runat="server" ConnectionString="<%$ ConnectionStrings:MyDatabaseConnectionString %>" SelectCommand="SELECT * FROM [Customer]" OnSelecting="SqlDataSource3_Selecting"></asp:SqlDataSource> </ContentTemplate> <Triggers> <asp:PostBackTrigger ControlID="Timer1" /> </Triggers> </asp:UpdatePanel>計時器背后的代碼是： protected void Timer1_Tick(object sender, EventArgs e) { GridView3.DataBind(); }

我像下面的代碼一樣更改了觸發(fā)器標簽，它起作用了:)
<Triggers> <asp:AsyncPostBackTrigger ControlID="Timer1" /> </Triggers>
