gridview如果要分页功能,就必须有OnPageIndexChanging事件

GridView如果设置了分页功能,而没有设置分页事件就会报类似下面的错误:

GridView“LogGridView”激发了未处理的事件“PageIndexChanging”。

正确的做法是,在gridview中增加OnPageIndexChanging事件,并对该事件写处理方法

<asp:GridView ID="LogGridView" runat="server" AutoGenerateColumns="False" 
            BackColor="White" BorderColor="White" BorderStyle="Ridge" BorderWidth="2px" 
            CellPadding="3" CellSpacing="1" GridLines="None"
            OnRowDeleting="LogGridView_RowDeleting" 
            DataKeyNames="log_id" AllowPaging="True" 
            onselectedindexchanged="LogGridView_SelectedIndexChanged"  
            [b]OnPageIndexChanging="LogGridView_PageIndexChanging"[/b]

CS事件:

/*
     *分页处理事件,gridview需要绑定OnPageIndexChanging事件 
     */
    protected void LogGridView_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        LogGridView.PageIndex = e.NewPageIndex;
        bindDataSet();
    }
