如何使用asp.net web頁面自定義分頁控件?

這幾天學習了一下自定義分頁控件,現將實現方法記錄下來,親測可以實現:

1.首先創建一個.ascx文件,命名為TurnPage,然後在里面寫控件前台展示的界面:

2.然後在TurnPage.ascx.cs里面寫相應的後台代碼,代碼如下:

namespace Web

{

public delegate void GoToPage(int PageNum);

public partial class TurnPage : System.Web.UI.UserControl

{

private GoToPage _GoToPage = null;

protected void Page_Load(object sender, EventArgs e)

public void InitControl(GoToPage GP)

{

_GoToPage = GP;

}

public int DataCount

{

get { return Int32.Parse(lbl_TotalCount.Text); }

set { lbl_TotalCount.Text = value.ToString(); }

}

public int CurrPageNum

{

get { return Int32.Parse(lbl_CurrPage.Text); }

set { lbl_CurrPage.Text = value.ToString(); }

}

public int TotalPageNum

{

get { return Int32.Parse(lbl_TotalPage.Text); }

set { lbl_TotalPage.Text = value.ToString(); }

}

public int PageSize

{

get { return Int32.Parse(ddl_PageSize.SelectedValue); }

}

protected void btn_FristPage_Click(object sender, EventArgs e)

protected void btn_PrevPage_Click(object sender, EventArgs e)

{

if (int.Parse(lbl_CurrPage.Text) > 1)

_GoToPage(int.Parse(lbl_CurrPage.Text) - 1);

else

_GoToPage(1);

}

protected void btn_NextPage_Click(object sender, EventArgs e)

{

if (int.Parse(lbl_CurrPage.Text) 0)

{

btn_FristPage.Enabled = true;

btn_PrevPage.Enabled = true;

btn_LastPage.Enabled = true;

btn_NextPage.Enabled = true;

}

else

{

btn_FristPage.Enabled = false;

btn_PrevPage.Enabled = false;

btn_LastPage.Enabled = false;

btn_NextPage.Enabled = false;

}

if (CurrPageNum == 1)

{

btn_FristPage.Enabled = false;

btn_PrevPage.Enabled = false;

}

if (CurrPageNum == TotalPageNum)

{

btn_LastPage.Enabled = false;

btn_NextPage.Enabled = false;

}

if (CurrPageNum == 0)

{

btn_FristPage.Enabled = false;

btn_PrevPage.Enabled = false;

btn_LastPage.Enabled = false;

btn_NextPage.Enabled = false;

}

}

protected void ddl_PageSize_SelectedIndexChanged(object sender, EventArgs e)

protected void btn_GO_Click(object sender, EventArgs e)

{

int pageNum;

if (int.TryParse(txt_PageNum.Text, out pageNum))

{

if (pageNum > TotalPageNum)

_GoToPage(TotalPageNum);

else if (pageNum

3.控件的方法就寫好了,現在要做的就是在其它頁面引用這個控件了,引用方法如下:

然後在頁尾還需配置一下:

4.這就是最後一步了,在你引用這個控件的頁面的後台代碼里寫下以下語句:

大功告成了!

以上就是本文的全部內容,希望對大家的學習有所幫助,也希望大家多多支持路飯。
