分頁 DataList不要設定DataSource

DataList

DataList

DataList private void Page_Load(object sender, System.EventArgs e) { // 在這裡放置使用者程式碼以初始化網頁 sqlDataAdapter1.Fill(dataSet31); if(!IsPostBack) ViewState["CurrentPage"]=1;//設定目前瀏覽第一頁 ViewState[“PageSize”]=10;//預設一次瀏覽五筆 BindData(); }

DataList public void BindData() { int TotalRecord,PageCount; //計算總筆數 TotalRecord = dataSet31.Tables["Orders"].Rows.Count; ViewState["TotalRecord"] = TotalRecord; tot_count.Text = "總筆數：" + TotalRecord.ToString(); //計算總頁數 PageCount = (TotalRecord-1) / Convert.ToInt32(ViewState["PageSize"]) +1; ViewState["PageCount"]=PageCount; tot_page.Text = "總頁數：" + ViewState["PageCount"].ToString(); ….接後頁

DataList //清空下拉頁數選單 pagelist.Items.Clear(); for(int i=1;i<=PageCount;i++) { ListItem lipage=new ListItem(Convert.ToString(i),Convert.ToString(i)); pagelist.Items.Add(lipage); } if(TotalRecord > 0) PagedDataSource pds=new PagedDataSource(); pds.DataSource=dataSet31.Tables["Orders"].DefaultView; pds.AllowPaging=true; pds.PageSize=Convert.ToInt32(ViewState["PageSize"]); pds.CurrentPageIndex=Convert.ToInt32(ViewState["CurrentPage"])-1; DataList1.DataSource = pds; DataList1.DataBind();

DataList

DataList 下拉

DataList private void pagelist_SelectedIndexChanged(object sender, System.EventArgs e) { ViewState["CurrentPage"]=pagelist.SelectedItem.Value; BindData(); }

DataList

DataList private void TextBox1_TextChanged(object sender, System.EventArgs e) { ViewState["PageSize"]=Convert.ToInt16(TextBox1.Text); BindData(); }

DataList 傳統按鈕跳頁方式 private void top_page_Click(object sender, System.EventArgs e) { // 首頁 ViewState["CurrentPage"] = 1; BindData(); }

DataList private void next_page_Click(object sender, System.EventArgs e) { int CurrentPage,PageCount; //下一頁 CurrentPage = (int)ViewState["CurrentPage"]; PageCount = (int)ViewState["PageCount"]; if(CurrentPage<PageCount) CurrentPage++; ViewState["CurrentPage"] = CurrentPage; BindData(); }

DataList private void pre_page_Click(object sender, System.EventArgs e) { int CurrentPage; //前一頁 CurrentPage = (int)ViewState["CurrentPage"]; if(CurrentPage>1) CurrentPage--; ViewState["CurrentPage"] = CurrentPage; BindData(); }

DataList private void last_page_Click(object sender, System.EventArgs e) { int PageCount; PageCount = (int)ViewState["PageCount"]; // 末頁 ViewState["CurrentPage"] = PageCount; BindData(); }

DataList 使用commandname方式跳頁

DataList 設定jump_page事件

DataList

DataList

private void jump_page(object sender, System. Web. UI. WebControls private void jump_page(object sender, System.Web.UI.WebControls.CommandEventArgs e) { int CurrentPage,PageCount; CurrentPage = (int)ViewState["CurrentPage"]; PageCount = (int)ViewState["PageCount"]; //按首上下末頁時 switch(e.CommandName) case "pre": if(CurrentPage>1) CurrentPage--; break; case "next": if(CurrentPage<PageCount) CurrentPage++; case "top": CurrentPage = 1; case "lst": CurrentPage = PageCount; } ViewState["CurrentPage"] = CurrentPage; BindData();

新增/修改

新增/修改 private void Button6_Click(object sender, System.EventArgs e) { // 修改 SqlDataAdapter da=new SqlDataAdapter("update employees set lastname='" + TextBox3.Text + "' where employeeid=" + Convert.ToInt32(TextBox2.Text),sqlConnection1); da.Fill(dataSet21,"employees"); sqlDataAdapter1.Fill(dataSet21); DataList1.DataBind(); BindData(); }
