我正在处理一个选项卡式页面（4 个选项卡 - 选项卡容器），其中 2 个使用相同的控件并具有不同的 gridview 和不同的数据源，可以编辑和添加项目。

编辑和添加项目工作正常，但是当我添加项目时，gridview 或页面需要刷新以显示新项目。使用 Response.Redirect 只会刷新页面并重定向到第一个选项卡。我正在处理选项卡 2 和 3，并且重定向需要指向相关选项卡，而不总是指向第一个选项卡。

关于如何做到这一点的任何建议？

我正在使用 Visual Studio 2010、C# ASP.Net

代码：

您可以为此目的使用查询字符串，如下所示

Response.Redirect("default.aspx?tab=1");
Response.Redirect("default.aspx?tab=2");
Response.Redirect("default.aspx?tab=3");

并在default.aspx 页面中。你可以做类似的事情

var tab = Request.QueryString["tab"];
switch(tab)
{
case "1":
//Bind data for first tab
break;
case "2":
//Bind data for second tab
break;
}

希望能帮助到你 ：）
