C# 首次加载页面：gridView中的页面索引不工作
我有两个网格视图：C# 首次加载页面：gridView中的页面索引不工作,c#,asp.net,gridview,C#,Asp.net,Gridview,我有两个网格视图：grvHeadline和gdvNotification，gdvNotification是按grvHeadline的选定项加载数据 页面加载时：gdvNotification的数据由grvHeadline的第一项加载 我的问题是： 页面加载是第一个：如果gdvNotification有分页（1,2,3，…），当我在gdvNotification中单击分页时，它不会运行。页面已重新加载，但页面索引为0 当我在grvHeadline中选择其他项目并重新选择第一个项目时，然后在gdvN
grvHeadlinegdvNotificationgdvNotificationgdvNotificationgrvHeadlinegdvNotificationgdvNotification0grvHeadlinegdvNotification我正在调试：当页面第一次加载时：我在
gdvNotificationIsPostBack=Truepageload（）gdvNotification的事件gdvNotification\u PageIndexChanging
这是我的密码：
protected void gdvNotification_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
logger.Debug("Gridview Headline page index changing .");
gdvNotification.PageIndex = e.NewPageIndex;
HeadlineSelected(hdfNotificationIdSelected.Value, e.NewPageIndex);
//gdvNotification.DataBind();
lbPageIndex.Text = (e.NewPageIndex + 1).ToString(CultureInfo.InvariantCulture);
}
及
private void HeadlineSelected（字符串notificationIdSelected，int索引）
