【中文标题】从数据库中逐行将数据写入文本框【英文标题】：Write data to textbox row by row from database 【发布时间】：2015-04-15 04:29:40 【问题描述】：我想在表格中逐行显示数据库中的数据
如何将数据库中的数据逐行写入每个文本框
（即）日期活动1，活动2等然后下一行日期活动1，活动2等。 如何编写正确的循环
我尝试获取第一行数据的代码：
private void GetActivity()
try
CON = new OracleConnection(Connection);
CON.Open();
OracleCommand COMMAND1 = new OracleCommand("Select ACTIVITYID,to_char(ACTIVITYDATE,'DD-MON-YYYY') as ACTIVITYDATE,TITLE,STARTTIME,ENDTIME,ACTIVITYTIME as TIMETAKEN from DAILY_ACTIVITIES1 where ACTIVITYDATE= (Select min(ACTIVITYDATE) from DAILY_ACTIVITIES1)", CON);
OracleDataReader READER = COMMAND1.ExecuteReader();
int count = READER.FieldCount;
if (READER.HasRows)
while (READER.Read())
if (Date1TextBox.Text == "")
Date1TextBox.Text = READER[1].ToString();
Date1TextBox.Enabled = false;
if (D1A1TextBox.Text == "")
D1A1TextBox.Text = "Title:" + READER[2].ToString() + "\n";
D1A1TextBox.Text += "Start-time:" + READER[3].ToString() + "\n";
D1A1TextBox.Text += "End-time:" + READER[4].ToString() + "\n";
D1A1TextBox.Text += "Timetaken:" + READER[5].ToString() + "\n";
D1A1TextBox.Enabled = false;
else
D1A1TextBox.Enabled = false;
if (D1A2TextBox.Text == "")
D1A2TextBox.Text = "Title:" + READER[2].ToString() + "\n";
D1A2TextBox.Text += "Start-time:" + READER[3].ToString() + "\n";
D1A2TextBox.Text += "End-time:" + READER[4].ToString() + "\n";
D1A2TextBox.Text += "Timetaken:" + READER[5].ToString() + "\n";
D1A2TextBox.Enabled = false;
else
D1A2TextBox.Enabled = false;
if (D1A3TextBox.Text == "")
D1A3TextBox.Text = "Title:" + READER[2].ToString() + "\n";
D1A3TextBox.Text += "Start-time:" + READER[3].ToString() + "\n";
D1A3TextBox.Text += "End-time:" + READER[4].ToString() + "\n";
D1A3TextBox.Text += "Timetaken:" + READER[5].ToString() + "\n";
D1A3TextBox.Enabled = false;
else
D1A3TextBox.Enabled = false;
if (D1A4TextBox.Text == "")
D1A4TextBox.Text = "Title:" + READER[2].ToString() + "\n";
D1A4TextBox.Text += "Start-time:" + READER[3].ToString() + "\n";
D1A4TextBox.Text += "End-time:" + READER[4].ToString() + "\n";
D1A4TextBox.Text += "Timetaken:" + READER[5].ToString() + "\n";
D1A4TextBox.Enabled = false;
else
D1A4TextBox.Enabled = false;
if (D1A5TextBox.Text == "")
D1A5TextBox.Text = "Title:" + READER[2].ToString() + "\n";
D1A5TextBox.Text += "Start-time:" + READER[3].ToString() + "\n";
D1A5TextBox.Text += "End-time:" + READER[4].ToString() + "\n";
D1A5TextBox.Text += "Timetaken:" + READER[5].ToString() + "\n";
D1A5TextBox.Enabled = false;
else
D1A5TextBox.Enabled = false;
if (D1A6TextBox.Text == "")
D1A6TextBox.Text = "Title:" + READER[2].ToString() + "\n";
D1A6TextBox.Text += "Start-time:" + READER[3].ToString() + "\n";
D1A6TextBox.Text += "End-time:" + READER[4].ToString() + "\n";
D1A6TextBox.Text += "Timetaken:" + READER[5].ToString() + "\n";
D1A6TextBox.Enabled = false;
else
D1A6TextBox.Enabled = false;
CON.Close();
catch (Exception et)
et.ToString();
【问题讨论】：
kumartyr ，你从哪里得到 D1A1TextBox~D1A6TextBox？ @AngusChung 这些都是放置在表格第一行的文本框，其中 multiline = true （即）突出显示的是 D1A3textbox 我知道，但是你怎么能直接在 GetActivity() 中使用它们呢？ 我在我的 webform 的 Pageload 中调用了这个方法 好的，我明白你的问题，你想要一个循环来做吗？ 【参考方案1】：@kumartyr，根据你的需要，你不想用Gridview。
所以，我重写了 GetActivity() 函数以进行 动态文本框 访问。
private void GetActivity()
try
CON = new OracleConnection(Connection);
CON.Open();
OracleCommand COMMAND1 = new OracleCommand("Select ACTIVITYID,to_char(ACTIVITYDATE,'DD-MON-YYYY') as ACTIVITYDATE,TITLE,STARTTIME,ENDTIME,ACTIVITYTIME as TIMETAKEN from DAILY_ACTIVITIES1 where ACTIVITYDATE= (Select min(ACTIVITYDATE) from DAILY_ACTIVITIES1)", CON);
OracleDataReader READER = COMMAND1.ExecuteReader();
int count = READER.FieldCount;
if (READER.HasRows)
int i = 1;
TextBox txtDate;
TextBox txtDA;
ContentPlaceHolder cph = (ContentPlaceHolder)this.Master.FindControl("MainContent");
while (READER.Read() && i <= 6)
if (i == 1)
txtDate = (TextBox)cph.FindControl(string.Format("Date0TextBox", i.ToString()));
txtDate.Text = READER[1].ToString();
txtDate.Enabled = false;
txtDA = (TextBox)cph.FindControl(string.Format("D1A0TextBox", i.ToString()));
if (txtDA.Text == "")
txtDA.Text = "Title:" + READER[2].ToString() + "\n";
txtDA.Text += "Start-time:" + READER[3].ToString() + "\n";
txtDA.Text += "End-time:" + READER[4].ToString() + "\n";
txtDA.Text += "Timetaken:" + READER[5].ToString() + "\n";
txtDA.Enabled = false;
i++;
CON.Close();
catch (Exception et)
et.ToString();

【参考方案2】：使用 GridView 并将您的 OracleCommand 绑定为数据源。您可以自定义每个单元格以显示您想要的数据，而无需进行任何循环或手动添加数千个文本框。
以下是包含大量示例的文档： https://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview(v=vs.110).aspx

【参考方案3】：你在使用GridView吗？，你可以在RowDataBound事件中创建行模板并一次性绑定网格视图
这些是绑定 gridview 的简单方法。 this 就是一个很好的例子
