急！急！急！Asp分页中的 跳转到第几页的后台代码怎么写！三层架构

[HelloWorldww]

小弟想用三层架构做分页，首页，上一页，下一页，尾页的后台代码都写好了，就差一个跳转到第几页的后台代码不知道怎么写了！哪位大侠帮帮忙！
下面是我已经完成的代码！！
//绑定
protected void Bind(int PageIndex)
{
PagedDataSource pds = new PagedDataSource();
pds.DataSource = BLL.result.GetSCaseList().DefaultView;
pds.AllowPaging = true;
pds.PageSize = 7;
lblTotalPage.Text = pds.PageCount.ToString();
lblCurrentPage.Text = (PageIndex + 1).ToString();
pds.CurrentPageIndex = PageIndex;
GridView1.DataSource = pds;
GridView1.DataBind();
}

//首页
protected void lnkFirst_Click(object sender, EventArgs e)
{
Bind(0);

}

//上一页
protected void lnkPrevious_Click(object sender, EventArgs e)
{

int CurrentIndex = Convert.ToInt32(lblCurrentPage.Text);
if (CurrentIndex == 1)
return;
Bind(CurrentIndex - 2);

}

//下一页
protected void lnkNext_Click(object sender, EventArgs e)
{
int CurrentIndex = Convert.ToInt32(lblCurrentPage.Text);
int PageCount = Convert.ToInt32(lblTotalPage.Text);
if (CurrentIndex == PageCount)
return;
Bind(CurrentIndex);
}

//最后一页
protected void lnkLast_Click(object sender, EventArgs e)
{
Bind(Convert.ToInt32(lblTotalPage.Text) - 1);
}


就还差点击跳转link_Click下的代码怎么写
<font>转到</font>
<asp:TextBox ID="txtlink" runat="server" Width="29px"></asp:TextBox>页
<asp:LinkButton ID="link" runat="server" TabIndex="1" Width="40px"
Font-Underline="False" CssClass="s" onclick="link_Click">转到</asp:LinkButton>
protected void link_Click(object sender, EventArgs e)
{

}

看看aspnetpager

[学城]

这关系到 你分页代码如何写的问题,PagedDataSource 里 我个人觉得, 只要传入当前页, 就能获取当前页的数据, 可使用存储过程实现.

网上搜索分页算法,可以利用存储过程在数据库中实现
再利用后台代码传入页数来获取该页的数据

在link_Click下的代码写

if(txtlink.Text <>"" || txtlink.Text <>null)
{
Bind(Convert.toInt32(txtlink.Text.Trim()))
}

[孟子E章]

int CurrentIndex =0;
int PageCount = Convert.ToInt32(lblTotalPage.Text);

Int32.TryParse(txtlink.Text,out CurrentIndex );

不就可以了吗
当然你需要验证输入

if(CurrentIndex <0 )CurrentIndex =0;
if(CurrentIndex >PageCount )CurrentIndex = PageCount ;

Bind(CurrentIndex);

[我说我行就是行]

使用aspnetpager不是更好嘛！

飘过啊~~~~~~~~~~

int CurrentIndex =0;
int PageCount = Convert.ToInt32(lblTotalPage.Text);

Int32.TryParse(txtlink.Text,out CurrentIndex );

当然你需要验证输入

if(CurrentIndex <0 )CurrentIndex =0;
if(CurrentIndex >PageCount )CurrentIndex = PageCount ;

Bind(CurrentIndex);

孟子E章？啥意思

[goldfishsky]

int CurrentIndex =0;

int PageCount = Convert.ToInt32(lblTotalPage.Text);

Int32.TryParse(txtlink.Text,out CurrentIndex );

if(CurrentIndex <0 )CurrentIndex =0;
if(CurrentIndex >PageCount )CurrentIndex = PageCount ;

Bind(CurrentIndex-1);

上一页下一页都写好了，跳转还是一样的啊。Bind(跳转的页数); 页数你要判断啊。
