GridView中的分页
我在GridView中建立了分页的模块，如图：[img=http://hi.csdn.net/space-3604927-do-album-picid-797835.html][/img]
代码如下：
protected void btnFirst_Click(object sender, EventArgs e)
{
switch (((LinkButton)sender).CommandArgument.ToString())
{
case "first":
dgdShowTest.PageIndex = 0;
break;
case "last":
dgdShowTest.PageIndex = dgdShowTest.PageCount - 1;
break;
case "prev":
dgdShowTest.PageIndex = dgdShowTest.PageIndex - 1; //显示错误
break;
case "next":
dgdShowTest.PageIndex = dgdShowTest.PageIndex + 1;
break;
case "go":
{
GridViewRow gvr = dgdShowTest.BottomPagerRow;
TextBox temp = (TextBox)gvr.FindControl("txtNewPageIndex");
int res = Convert.ToInt32(temp.Text.ToString());
dgdShowTest.PageIndex = res - 1;
}
break;
}
DataBind();
}
实现时出现了几个错误/问题：
1、当按上一页时：指定的参数已超出有效值的范围。 参数名: value 。异常详细信息: System.ArgumentOutOfRangeException: 指定的参数已超出有效值的范围。源错误是上面标明的语句
2、按首页、下一页、尾页、go都无数据显示（表格是不止一页的）
请各位大虾指教！谢谢！ --------------------编程问答-------------------- 分页

}
补充：.NET技术 , ASP.NET
