如何動(dòng)態(tài)生成table并實(shí)現(xiàn)分頁(yè)效果

這篇文章將為大家詳細(xì)講解有關(guān)如何動(dòng)態(tài)生成table并實(shí)現(xiàn)分頁(yè)效果，小編覺(jué)得挺實(shí)用的，因此分享給大家做個(gè)參考，希望大家閱讀完這篇文章后可以有所收獲。

前臺(tái)代碼:

復(fù)制代碼 代碼如下:

<table >
<tr>
<td>
搜索字： <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:Button ID="Button1" runat="server" Text="搜索" OnClick="Button1_Click" />
</td>
</tr>
<tr>
<td>
<div id="divmain" runat="server"> </div>
</td>
</tr>
<tr>
<td>
<asp:Button ID="btnFirst" runat="server" Text="首頁(yè)" OnClick="btnFirst_Click" />
<asp:Button ID="btnPro" runat="server" Text="上一頁(yè)" OnClick="btnPro_Click" />
<asp:Button ID="btnNext" runat="server" Text="下一頁(yè)" OnClick="btnNext_Click" />
<asp:Button ID="btnLast" runat="server" Text="末頁(yè)" OnClick="btnLast_Click" />
&nbsp;<asp:Label ID="labCountPage" runat="server"></asp:Label>
<asp:Label ID="labpage" runat="server"></asp:Label>
<asp:TextBox ID="TextBox2" runat="server" Width="16px"></asp:TextBox>
<asp:Button ID="btnGo" runat="server" OnClick="btnGo_Click" Text="Go" />
</td>
</tr>
</table>

后臺(tái)代碼:

復(fù)制代碼 代碼如下:

{
if (!IsPostBack)
{
ViewState["pageIndex"] = 1;
dataPage();
}
}
private void dataPage()

#region 傳遞SQl語(yǔ)句實(shí)現(xiàn)分頁(yè)并對(duì)搜索實(shí)現(xiàn)分頁(yè)默認(rèn)顯示兩條記錄

if (sum % 2 == 0)
{
ViewState["pageCount"] = sum/2;
}
else

}
conn.Close();
conn.Dispose();
