分頁分頁DataListDataList 不要設定不要設定 DataSourceDataSource

DataListDataList

DataListDataList

DataListDataList

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();

} }

DataListDataListpublic 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

DataListDataList// 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();

}}

DataListDataList

DataListDataList下拉

DataListDataList

private void pagelist_SelectedIndexChanged(object sender, System.EventArgs e){

ViewState["CurrentPage"]=pagelist.SelectedItem.Value;BindData();

}

DataListDataList

DataListDataList

private void TextBox1_TextChanged(object sender, System.EventArgs e){

ViewState["PageSize"]=Convert.ToInt16(TextBox1.Text);BindData();

}

DataListDataList

傳統按鈕跳頁方式

private void top_page_Click(object sender, System.EventArgs e){

// 首頁ViewState["CurrentPage"] = 1;BindData();

}

DataListDataList

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();

}

DataListDataList

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();

}

DataListDataList

private void last_page_Click(object sender, System.EventArgs e){

int PageCount;PageCount = (int)ViewState["PageCount"];// 末頁ViewState["CurrentPage"] = PageCount;BindData();

}

DataListDataList使用 commandname 方式跳頁

DataListDataList

設定 jump_page 事件

DataListDataList

DataListDataList

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++;break;

case "top":CurrentPage = 1;break;

case "lst":CurrentPage = PageCount;break;

}ViewState["CurrentPage"] = CurrentPage;BindData();

}

新增新增 // 修改修改

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();

}
