从不同行表中的checkboxlist中读取多个选中的复选框 [英] read multiple checked checkbox from checkboxlist in different rows of table

问题描述

on page_Init（）创建新表行和列。每一行都有标签，这将有问题，每个标签后都会有复选框列表..（类似调查，每个问题和控件都从数据库中重新发送）

r = new TableRow（）;

c = new TableCell（）;

Label dynamicLabel = new Label（）;

dynamicLabel.ID =lbl+ x; // x是增量

dynamicLabel.Text = questionNum +）+ questionText;

c.Controls.Add（dynamicLabel）;

r .Cells.Add（c）;

tbl.Rows.Add（r）;



然后复选框是动态创建的

ckbx = new CheckBoxList（）;

ckbx.ID =c+ x; // x是增量

ckbx.Items.Add（new ListItem（optionField））;

c.Controls.Add（ckbx）;

r.Cells.Add（c）;

tbl.Rows.Add（r）;

读取已选中的复选框

for （int i = 0; i< ckbx.Items.Count; i ++）

{

if（ckbx.Items [i] .Selected）

{

xval = new Label（）;

xval.ID =x+ y;

xval.Text = ckbx .Items [i] .Text;

show.Controls.Add（xval）;

}

}

在Default.aspx中

< form id =form1runat =server>

on page_Init() new table row and column is created. Every row will have label that will have quesion and after every label there will be checkboxlist..(its like survey where every question and controls are reterived from database)
r = new TableRow();
c = new TableCell();
Label dynamicLabel = new Label();
dynamicLabel.ID = "lbl" + x; //x is incremental
dynamicLabel.Text = questionNum+")"+questionText;
c.Controls.Add(dynamicLabel);
r.Cells.Add(c);
tbl.Rows.Add(r);

then checkboxlist is created dynamically
ckbx = new CheckBoxList();
ckbx.ID = "c"+x; //x is incremental
ckbx.Items.Add(new ListItem(optionField));
c.Controls.Add(ckbx);
r.Cells.Add(c);
tbl.Rows.Add(r);
To read checkbox that are checked
for (int i = 0; i < ckbx.Items.Count; i++)
{
if (ckbx.Items[i].Selected)
{
xval = new Label();
xval.ID = "x" + y;
xval.Text = ckbx.Items[i].Text;
show.Controls.Add(xval);
}
}
in Default.aspx
<form id="form1" runat="server">

< asp ：表ID =tblrunat =server>



< asp：按钮ID =btnSetrunat =serverText =Submit onclick =btnSet_Click/>

< asp：Panel ID =showrunat =server>

<asp:Table ID="tbl" runat="server" >

<asp:Button ID="btnSet" runat="server" Text="Submit" onclick="btnSet_Click" />
<asp:Panel ID="show" runat="server">

< / form>
