如何在for循环中保存多个Textbox和radiobutton的值 [英] How to save multiple Textbox and radiobutton's value in for loop
问题描述
我使用linq到sql，我动态按照数据库的值创建textobes和radiobutton，
这是代码，
var r = 来自 a in db.EMR_EVENTs
其中 a.EventID ==（ int ）会话[ eventid]
选择 new
{
No_Of_Extra_Invitee = a.Allowed_guest_per_invitee
};
var ev1 = r.First（）;
int ？ count = ev1.No_Of_Extra_Invitee;
int ？ rowCount = ev1.No_Of_Extra_Invitee;
会话[ rc] = rowCount;
for （ int i = 0 ; i < rowCount; i ++）
{
TextBox txtfirstname = new TextBox（）;
TextBox txtlastname = new TextBox（）;
TextBox txtemail = new TextBox（）;
RadioButton chkmale = new RadioButton（）;
RadioButton chkfemale = new RadioButton（）;
txtfirstname.ID = txtfirstname + i。的ToString（）;
txtlastname.ID = txtlastname + i.ToString（）;
txtemail.ID = txtemail + i.ToString（）;
txtfirstname.CssClass = form-control;
txtlastname.CssClass = form-control;
txtemail.CssClass = form-control;
txtemail.Text = 电子邮件地址;
txtfirstname.Text = 名字;
txtlastname.Text = 姓氏;
chkmale.ID = chkmale + i。的ToString（）;
chkfemale.ID = chkfemale + i.ToString（）;
chkmale.Text = 男;
chkfemale.Text = 女性;
pnl.Controls.Add（txtfirstname）;
pnl.Controls.Add（txtlastname）;
pnl.Controls.Add（txtemail）;
pnl.Controls.Add（chkmale）;
pnl.Controls.Add（chkfemale）;
}
如果我得到No_Of_Extra_Invitee = 2那么我有6个文本框和4个radiobuttons
现在我想保存这个控件的值（文本），虽然我给它默认文本，但我想保存它的运行时值，所以在提交按钮我实现这样，
受保护 void 提交（对象发件人，EventArgs e）
{
int rccount = Convert.ToInt32（会话[ rc]）;
ExtraInviteeBL eb = new ExtraInviteeBL（）;
for （ int i = 0 ; i< rccount; i ++）
{
// 添加值的逻辑textbox's和radiobutton在数据库中
}
但是现在我不知道这个文本框和radiobuttns的插值如何能有人给我建议
提前谢谢..！
< blockquote>首先你宣布像
TextBox txtfirstname;
TextBox txtlastname;
TextBox txtemail;
RadioButton chkmale;
RadioButton chkfemale;
;
然后尝试简单的更新
................
...................... ..........
for （ int i = 0 ; i < rowCount; i ++）
{
txtfirstname = < span class =code-keyword> new TextBox（）;
txtlastname = new TextBox（）;
txtemail = new TextBox（）;
chkmale = new RadioButton（）;
chkfemale = new RadioButton（）;
.............
.............
更新
i我正在使用此代码
for textbox
DataTable dtSpci = new DataTable（）;
dtSpci.Columns.Add（）;
foreach （控制控件 in pnl_details.Controls）
{
TextBox txtTemp =控制为 TextBox;
if （txtTemp TextBox）
{
dtSpci.Rows 。新增（txtTemp.Text）;
}
}
单选按钮
更改上面的代码，将文本框替换为radiobutton
注意
这里保存将文本框名称转换为数据表...
插入表格
inser into table_name values（dtSpci.Rows [ 1 ].ItemArray.GetValue( 0 ）。ToString（），dtSpci.Rows [ 2 ] .ItemArray.GetValue（ 0 ）。ToString（）等...
试试这段代码，希望它有点帮助...
我得到了解决方案，但我仍然对它如何在数据库中保存价值感到困惑，
就像假设我有这种类型的解决方案
TextBox ti =（TextBox）pnl.FindControl（ txtfirstname + i.ToString（））;
eb.First_Name = Session [ txtfirstname + i.ToString（）]。ToString （）;
假设我有这张桌子，
id |名字
1 ktn
2 ravi
3 vijay
这里是ktn， ravi和vijay是我的txtfirstname文本框的值，用户在运行时输入。
然后我如何将其保存为这样，
i'我很困惑，任何解决方案都是最受欢迎的。
嘿，这样做但现在我遇到了主要问题，这是我的代码，
用于创建控件我使用此方法：
private void generateDynamicControls（）
{
int rowCount = Convert.ToInt32（会话[ rc]）;
for （ int i = 0 ; i < rowCount; i ++）
{
TextBox txtfirstname = new TextBox（）;
TextBox txtlastname = new TextBox（）;
TextBox txtemail = new TextBox（）;
RadioButton chkmale = new RadioButton（）;
RadioButton chkfemale = new RadioButton（）;
txtfirstname.ID = txtfirstname + i。的ToString（）;
txtlastname.ID = txtlastname + i.ToString（）;
txtemail.ID = txtemail + i.ToString（）;
txtfirstname.CssClass = form-control;
txtlastname.CssClass = form-control;
txtemail.CssClass = form-control;
txtemail.Text = 电子邮件地址;
txtfirstname.Text = 名字;
txtlastname.Text = 姓氏;
chkmale.ID = chkmale + i。的ToString（）;
chkfemale.ID = chkfemale + i.ToString（）;
chkmale.Text = 男;
chkfemale.Text = 女性;
pnll.Controls.Add（txtfirstname）;
pnll.Controls.Add（txtlastname）;
pnll.Controls.Add（txtemail）;
pnll.Controls.Add（chkmale）;
pnll.Controls.Add（chkfemale）;
}
}
保存它的价值我使用这种方法，
protected 无效提交（对象发件人，EventArgs e）
{
int rccount = Convert.ToInt32（Session [ rc]）;
string strValue1 = string .Empty;
string strValue2 = string .Empty;
string strValue3 = string .Empty;
ExtraInviteeBL eb = new ExtraInviteeBL（）;
for （ int i = 0 ; i < rccount; i ++）
{
string firstname = txtfirstname + i.ToString（）;
string lastname = txtlastname + i.ToString（）;
string mail = txtemail + i.ToString（）;
TextBox tb = pnll.FindControl（firstname） as TextBox;
TextBox tb1 = pnll.FindControl（lastname） as TextBox;
TextBox tb2 = pnll.FindControl（mail） as TextBox;
strValue1 + = tb.Text + \ n;
strValue2 + = tb.Text + \ n;
strValue3 + = tb.Text + \ n;
eb.First_Name = strValue1;
eb.Last_Name = strValue2;
eb.E_mailID = strValue3;
eb.Ive_Invited_By = Convert.ToInt32（会话[ inviteby]）;
}
eb.insert（）;
}
现在所有记录只保存在一个id中，在表格中我有客人表，它包含guestid，这是主键。
它自动增加然后我如何保存它的值，因为for循环增加，
（我的意思是我的值增量）
给我建议请
提前致谢。
I use linq to sql,i dynamicallu create textobes and radiobuttons as per value of database,
Here is the code for that,
var r = from a in db.EMR_EVENTs
where a.EventID == (int)Session["eventid"]
select new
{
No_Of_Extra_Invitee=a.Allowed_guest_per_invitee
};
var ev1 = r.First();
int? count = ev1.No_Of_Extra_Invitee;
int? rowCount = ev1.No_Of_Extra_Invitee;
Session["rc"] = rowCount;
for (int i = 0; i < rowCount; i++)
{
TextBox txtfirstname = new TextBox();
TextBox txtlastname = new TextBox();
TextBox txtemail = new TextBox();
RadioButton chkmale = new RadioButton();
RadioButton chkfemale = new RadioButton();
txtfirstname.ID = "txtfirstname" + i.ToString();
txtlastname.ID = "txtlastname" + i.ToString();
txtemail.ID = "txtemail" + i.ToString();
txtfirstname.CssClass = "form-control";
txtlastname.CssClass = "form-control";
txtemail.CssClass = "form-control";
txtemail.Text = "E-Mail Address";
txtfirstname.Text = "First Name";
txtlastname.Text = "Last Name";
chkmale.ID = "chkmale" + i.ToString();
chkfemale.ID = "chkfemale" + i.ToString();
chkmale.Text = "Male";
chkfemale.Text = "Female";
pnl.Controls.Add(txtfirstname);
pnl.Controls.Add(txtlastname);
pnl.Controls.Add(txtemail);
pnl.Controls.Add(chkmale);
pnl.Controls.Add(chkfemale);
}
if i got No_Of_Extra_Invitee=2 then i got 6 textbox and 4 radiobuttons
Now i want to saved this control's value(text),though i give it default text,but i want to save it's runtime value so in submit button i implement like this,
protected void Submit(object sender, EventArgs e)
{
int rccount = Convert.ToInt32(Session["rc"]);
ExtraInviteeBL eb = new ExtraInviteeBL();
for (int i = 0; i <rccount; i++)
{
//logic for add value of textbox's and radiobutton's in database
}
but now i don't know how insert value of this textbox and radiobuttns can anyone give me suggestion for that
Thanks in advance..!
first you declare like
TextBox txtfirstname; TextBox txtlastname; TextBox txtemail; RadioButton chkmale ; RadioButton chkfemale ;;
then try your with simple update
................ ................................ for (int i = 0; i < rowCount; i++) { txtfirstname = new TextBox(); txtlastname = new TextBox(); txtemail = new TextBox(); chkmale = new RadioButton(); chkfemale = new RadioButton(); ............. .............
Updated
i am using this code
for textbox
DataTable dtSpci = new DataTable(); dtSpci.Columns.Add(); foreach (Control controls in pnl_details.Controls) { TextBox txtTemp = controls as TextBox; if (txtTemp is TextBox) { dtSpci.Rows.Add(txtTemp.Text); } }
for radio button
change the above code,replace textbox in to radiobutton
Note
here save the textbox name into datatable ...
Insert into Table
inser into table_name values (dtSpci.Rows[1].ItemArray.GetValue(0).ToString(),dtSpci.Rows[2].ItemArray.GetValue(0).ToString() etc...
try this code, hope its helps a bit...
i got solution of this but i'm still confuse on it that how i save value in database,
like suppose i have this type of solution
TextBox ti = (TextBox)pnl.FindControl("txtfirstname" + i.ToString()); eb.First_Name = Session["txtfirstname" + i.ToString()].ToString();
suppose i have this table,
id | firstname
1 ktn
2 ravi
3 vijay
here ktn,ravi and vijay are my txtfirstname textbox's value which is user enter at runtime.
then how i save it in like this,
i'm confuse about it,any solution is most welcome.
Hey do this but now i face the main problem,here is the my code,
for create control i use this method:
private void generateDynamicControls() { int rowCount=Convert.ToInt32(Session["rc"]); for (int i = 0; i < rowCount; i++) { TextBox txtfirstname = new TextBox(); TextBox txtlastname = new TextBox(); TextBox txtemail = new TextBox(); RadioButton chkmale = new RadioButton(); RadioButton chkfemale = new RadioButton(); txtfirstname.ID = "txtfirstname" + i.ToString(); txtlastname.ID = "txtlastname" + i.ToString(); txtemail.ID = "txtemail" + i.ToString(); txtfirstname.CssClass = "form-control"; txtlastname.CssClass = "form-control"; txtemail.CssClass = "form-control"; txtemail.Text = "E-Mail Address"; txtfirstname.Text = "First Name"; txtlastname.Text = "Last Name"; chkmale.ID = "chkmale" + i.ToString(); chkfemale.ID = "chkfemale" + i.ToString(); chkmale.Text = "Male"; chkfemale.Text = "Female"; pnll.Controls.Add(txtfirstname); pnll.Controls.Add(txtlastname); pnll.Controls.Add(txtemail); pnll.Controls.Add(chkmale); pnll.Controls.Add(chkfemale); } }
for save it's value i use this method,
protected void Submit(object sender, EventArgs e) { int rccount = Convert.ToInt32(Session["rc"]); string strValue1 = string.Empty; string strValue2 = string.Empty; string strValue3 = string.Empty; ExtraInviteeBL eb = new ExtraInviteeBL(); for (int i = 0; i < rccount; i++) { string firstname = "txtfirstname" + i.ToString(); string lastname = "txtlastname" + i.ToString(); string mail = "txtemail" + i.ToString(); TextBox tb = pnll.FindControl(firstname) as TextBox; TextBox tb1 = pnll.FindControl(lastname) as TextBox; TextBox tb2 = pnll.FindControl(mail) as TextBox; strValue1 += tb.Text + "\n"; strValue2 += tb.Text + "\n"; strValue3 += tb.Text + "\n"; eb.First_Name = strValue1; eb.Last_Name = strValue2; eb.E_mailID = strValue3; eb.Ive_Invited_By = Convert.ToInt32(Session["invitedby"]); } eb.insert(); }
now all records save only in one id,in table i have guest table,and it contain guestid,which is primary key.
it increment automatically then how i save it's value as per for loop increases,
(i mean i's value increment)
give me suggestion please
Thanks in advance.
