Question

在我添加这些代码之前，我收到有关GridView触发的事件PageIndexChanging的错误，该事件未被处理，并且对于Sorting也是如此。所以我添加了这个事件代码然后我得到编译错误说，“CS1061：'ASP.serveredit_aspx'不包含'GridViewServer_PageIndexChanging'的定义，并且没有扩展方法'GridViewServer_PageIndexChanging'接受'ASP.serveredit_aspx'类型的第一个参数可以被发现”。但是我已经在C＃中拥有了该事件代码。请帮忙

这是我的GridView属性代码，

<asp:GridView ID="GridViewServer" runat="server" AllowPaging="True" AllowSorting="True" OnPageIndexChanging="GridViewServer_PageIndexChanging" OnSorting="GridViewServer_Sorting" AutoGenerateColumns="False" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" CellPadding="3" DataKeyNames="ServerName" GridLines="None" ShowFooter="True" onrowcancelingedit="GridViewServer_RowCancelingEdit" 
        onrowdeleting="GridViewServer_RowDeleting" onrowediting="GridViewServer_RowEditing" 
        onrowupdating="GridViewServer_RowUpdating">

此活动背后的C＃代码，

private string ConvertSortDirectionToSql(SortDirection sortDirection)
    {
        string newSortDirection = String.Empty;

        switch (sortDirection)
        {
            case SortDirection.Ascending:
                newSortDirection = "ASC";
                break;

            case SortDirection.Descending:
                newSortDirection = "DESC";
                break;
        }

        return newSortDirection;
    }

    protected void gridViewServer_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        GridViewServer.PageIndex = e.NewPageIndex;
        GridViewServer.DataBind();
    }

    protected void gridViewServer_Sorting(object sender, GridViewSortEventArgs e)
    {
        DataTable dataTable = GridViewServer.DataSource as DataTable;

        if (dataTable != null)
        {
            DataView dataView = new DataView(dataTable);
            dataView.Sort = e.SortExpression + " " + ConvertSortDirectionToSql(e.SortDirection);

            GridViewServer.DataSource = dataView;
            GridViewServer.DataBind();
        }
    }

我意识到gridViewServer_PageIndexChanging和gridViewServer_Sorting是小写的。我忘了把它搞定。
