如何停止刷新页面上的事件

我更喜欢使用以下方法来检测底层请求是否被双重发布。

private bool refreshState;
private bool isDoublePosted;

protected bool IsInDoublePosting
{
    get 
    {
        return isDoublePosted;
    }
}

protected override void LoadViewState(object savedState)
{
    object[] states = (object[])savedState;
    base.LoadViewState(states[0]);
    refreshState = Convert.ToBoolean(states[1]);
    isDoublePosted = (refreshState == Convert.ToBoolean(Session["IsInDoublePosting"]));
}

protected override object SaveViewState()
{
    Session["IsInDoublePosting"] = refreshState;
    object[] states = new object[3];
    states[0] = base.SaveViewState();
    states[1] = !refreshState;
    return states;
}

在按钮单击事件处理程序中:

    if (!this.IsInDoublePosting)
    { 
        // your code goes here
    }

在处理请求后,从服务器端提交按钮事件发出响应。重定向(“yourpage”)
