动态绑定gridview

Question

我在页面加载时绑定了我的 gridview，但我希望在用户向下滚动时绑定数据。

我已经使用存储过程来绑定gridview

当用户每 10 行后向下滚动时，如何在 gridview 中动态绑定行？

<asp:GridView ID="GridViewUserSkillQuery" runat="server" AutoPostBack="True" AutoGenerateColumns="false" Width="100%" RowStyle-ForeColor="Black" GridLines="None" OnDataBound="GridViewUserSkillQuery_DataBound">

Answer 1

您可以使用 AJAX 来做到这一点。困难的部分是下面收集的行的 EDIT 和 DELETE 函数。
