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

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();
}

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");
