LinkButton点击触发不到事件

.net我自定义的Prpeater分页翻页按钮触发不到事件怎么回事？昨天还行的，今天突然不行了，重新写过事件也不行，跳转按钮可以实现的，就翻页按钮不可以。单独把这个分页和Repeater绑定的数据单独复制出来新建页面又可以，纠结！！
aspx分页代码如下：
<asp:Label ID="LblRecordCount" runat="server"></asp:Label>
<asp:LinkButton ID="btnF" CommandArgument="first" OnClick="btn_Click" runat="server" >首页 </asp:LinkButton>
<asp:LinkButton ID="btnP" CommandArgument="prev" runat="server" OnClick="btnP_Click">上一页 </asp:LinkButton>
<asp:LinkButton ID="btnN" CommandArgument="next" runat="server" OnClick="btnN_Click">下一页 </asp:LinkButton>
<asp:LinkButton ID="btnL" CommandArgument="last" runat="server" OnClick="btnL_Click">尾页 </asp:LinkButton>
页次<asp:Label ID="LblCurrentIndex" runat="server" Text="1"></asp:Label>/
<asp:Label ID="LblPageCount" runat="server"></asp:Label>
跳转到：<asp:TextBox ID="TextBox1" runat="server" Width="28px"></asp:TextBox>
<asp:Button ID="Button1" runat="server" onclick="Button1_Click"
Text="跳转" />

<asp:Label ID="Label1" runat="server" ForeColor="Red" Font-Size="12px"></asp:Label>
</div>
</div>
</div>
</div>

cs文件代码：
protected void Page_Load(object sender, EventArgs e)
{
if ( !IsPostBack )
{
PageNews();
}
}
private void PageNews()
{
SqlConnection mystr = new SqlConnection(ConfigurationManager.ConnectionStrings["robotConnectionString"].ConnectionString);
mystr.Open();
string all_sql = "select * from tb_News order by news_id desc";
DataSet ds = new DataSet();
SqlDataAdapter da = new SqlDataAdapter(all_sql, mystr);
da.Fill(ds, "news");

PagedDataSource pds = new PagedDataSource();
pds.DataSource = ds.Tables["news"].DefaultView;
pds.AllowPaging = true;
pds.PageSize = 5;
int curpage = Convert.ToInt32(LblCurrentIndex.Text);//获取当前页
pds.CurrentPageIndex = curpage - 1;
btnFirst.Enabled = true;
btnLast.Enabled = true;
btnNext.Enabled = true;
btnPrev.Enabled = true;
//判断按钮是否可以点击
if ( pds.IsFirstPage )
{
btnFirst.Enabled = false;
btnPrev.Enabled = false;
}
if ( pds.IsLastPage )
{
btnLast.Enabled = false;
btnNext.Enabled = false;
}
LblPageCount.Text = Convert.ToString(pds.PageCount);
string allcount = "select count(*) from tb_News";
LblRecordCount.Text = "共" + Convert.ToString(SqlHelper.ExecuteScalar(allcount, null)) + "条记录";
rpt1.DataSource = pds;
rpt1.DataBind();
}

protected void btnFirst_Click(object sender, EventArgs e)
{
LblCurrentIndex.Text = "1";
PageNews();
}
protected void btnPrev_Click(object sender, EventArgs e)
{
LblCurrentIndex.Text = Convert.ToString(Convert.ToInt32(LblCurrentIndex.Text) - 1);
PageNews();
}
protected void btnNext_Click(object sender, EventArgs e)
{
LblCurrentIndex.Text = Convert.ToString(Convert.ToInt32(LblCurrentIndex.Text) + 1);
PageNews();
}
protected void btnLast_Click(object sender, EventArgs e)
{
LblCurrentIndex.Text = LblPageCount.Text;
PageNews();
}
protected void Button1_Click(object sender, EventArgs e)
{
int num = Convert.ToInt32(TextBox1.Text);
int sum = Convert.ToInt32(LblPageCount.Text);
if ( num < 0 || num > sum )
{
Label1.Text = "请输入有效数值";
}
else
{
LblCurrentIndex.Text = num.ToString();
PageNews();
}
}
