Question

当用户从中选择一行时，我希望 Formview 以插入模式开始，然后更改为编辑模式 Gridview 在同一页面中。

Formview具有内联属性： DefaultMode =“插入”

如何做到这一点，为什么这不起作用？

protected void GridView1_SelectedIndexChanged(object sender, System.EventArgs e)   
{   
    FormView1.ChangeMode(FormViewMode.Edit);
}

数据按预期更新，但似乎没有事件发生......以下重定向根本不会发生：

protected void FormView1_ItemUpdated(Object sender, FormViewCommandEventArgs e)
{
    Response.Redirect("www.stackoverflow.com");
}

最初的问题很可能就是那里，你不觉得吗？问题是，如何使事件按预期工作？

无法在GridView_SelectedIndexChanged上更改Formview模式
