C# c中的分页和行命令#

在我的cs页面的代码隐藏中，我插入了分页：

protected void Paginate(object sender, CommandEventArgs e)
{
    int intCurIndex = gvProducts.PageIndex;

    switch (e.CommandArgument.ToString().ToLower())
    {
        case "First":
            gvProducts.PageIndex = 0;
            break;
        case "Prev":
            gvProducts.PageIndex = intCurIndex - 1;
            break;
        case "Next":
            gvProducts.PageIndex = intCurIndex + 1;
            break;
        case "Last":
            gvProducts.PageIndex = gvProducts.PageCount - 1;
            break;
    }
    gvProducts.DataBind();
}

但是如果将代码添加到我的cs页面的行命令事件后，此分页将不起作用：

protected void gvProducts_RowCommand(object sender, GridViewCommandEventArgs e)
{
    int rowindex = Convert.ToInt32(e.CommandArgument.ToString());
    GridView g2 = (GridView)gvProducts.Rows[rowindex].FindControl("GridView2");

    if (e.CommandName == "Details")
    {
       ....
    }
    else
    {
       ....
    }
}

这是错误，如何解决此问题：

输入字符串的格式不正确

在这一行：

int rowindex = Convert.ToInt32(e.CommandArgument.ToString());

编辑#01

<PagerTemplate>
    <asp:ImageButton ID="ImageButton1" runat="server" ImageUrl="/aspnet/img/bot_back_doppio.gif"
        CommandArgument="First" CommandName="Page" />
    <asp:ImageButton ID="ImageButton2" runat="server" ImageUrl="/aspnet/img/bot_back.gif"
        CommandArgument="Prev" CommandName="Page" />
    Page
        <asp:DropDownList ID="ddlPages" runat="server" AutoPostBack="True" CssClass="ddl_Class"
            OnSelectedIndexChanged="DDLPages_SelectedIndexChanged">
        </asp:DropDownList>
    of
        <asp:Label ID="lblPageCount" runat="server"></asp:Label>
    <asp:ImageButton ID="ImageButton3" runat="server" ImageUrl="/aspnet/img/bot_next.gif"
        CommandArgument="Next" CommandName="Page" />
    <asp:ImageButton ID="ImageButton4" runat="server" ImageUrl="/aspnet/img/bot_next_doppio.gif"
        CommandArgument="Last" CommandName="Page" />
</PagerTemplate>

调用

Paginate

方法时？您在

e.CommandArgument

中得到的值是多少？调用

gvProducts\u RowCommand

时？您是否在aspx中将行索引设置为e.CommandArgument？您可以查看以了解它是如何在RowCommand事件中获取行索引的。@ChetanRanpariya感谢您的帮助，请参阅我的第一篇文章中的编辑#01question@ChetanRanpariya非常感谢。在我的第一个问题中关于编辑#03的解决方案
