似乎当多个更新小组位于一个页面上时, 每当一个 AsyncPostBack 在一个页面上出现时, 其他人都会重新加载他们的 html 。 是否有一条路可以绕过它?
示例
< 强度 > 示例. aspx
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<div style="border: 1px solid black;">
<asp:TextBox runat="server" ID="txtTEST1" />
<asp:Label runat="server" ID="lblTEST1" />
<asp:Button runat="server" ID="btnTEST1" Text="AsyncPostBack1" />
<div onclick="this.innerHTML= Wooo! ">Click Me - UpdatePanel1</div>
</div>
</ContentTemplate>
</asp:UpdatePanel>
<div onclick="this.innerHTML= Wooo! " style="padding: 1em;">Click Me. I m not part of an Update Panel</div>
<asp:UpdatePanel ID="UpdatePanel2" runat="server">
<ContentTemplate>
<div style="border: 1px solid black;">
<asp:TextBox runat="server" ID="TextBox1" />
<asp:Label runat="server" ID="Label1" />
<asp:Button runat="server" ID="Button1" Text="AsyncPostBack2" />
<div onclick="this.innerHTML= Wooo! ">Click Me - UpdatePanel2</div>
</div>
</ContentTemplate>
</asp:UpdatePanel>
< 强度 > 示例. aspx.vb
Protected Sub btnTEST1_Click(sender As Object, e As EventArgs) Handles btnTEST1.Click
lblTEST1.Text = "Refreshed at " & DateTime.Now.ToString()
End Sub
Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Label1.Text = "Refreshed at " & DateTime.Now.ToString()
End Sub
<强度 > 测试问题
- Click on all 3 of the divs with the "Click Me" text so that HTML is altered inside and outside of the UpdatePanels.
- Click one of the buttons labeled "AsyncPostBack". Regardless on which one is clicked, both UpdatePanels will have their HTML rerendered and replaced, as seen by the 2 divs inside the UpdatePanels resetting to their original text.
所以我要问, 能否在同一页上设置多个更新小组, 以免每次出现一个 AsyncPostBack 事件时彼此重复 。
