ASP.net creating dynamic Radio Button List

问题:

I need to create dynamic radio button in my table.I have a table in default.aspx(id =table1) but in .cs I dont access to table1 this is frist problem. if I can reach it, I want to create dynamic radio button List . For example I want to create 8 radio button list which have 5 members. I think I do this with foreach block. I find this code samples :

foreach (?) {     RadioButton radioButton = new RadioButton();     radioButton.Text = answer.Text;     radioButton.GroupName = question.Id.ToString();     radioButton.ID = question.Id + "_" + answer.Id;      TableRow answerRow = new TableRow();     TableCell answerCell = new TableCell();     TableCell emptyCell = new TableCell();      emptyCell.ColumnSpan = 2;      answerCell.Controls.Add(radioButton);     answerRow.Cells.Add(emptyCell);     answerRow.Cells.Add(answerCell);      table.Rows.Add(answerRow); }

use runat="server" attribute to table:

<table id="table1" runat="server""> </table> 

From code, you can add rows and cells dynamically. For example:

for (int j = 0; j < 5; j++) {     HtmlTableRow row = new HtmlTableRow();     for (int i = 0; i < 3; i++)     {         HtmlTableCell cell = new HtmlTableCell();         RadioButton radioButton = new RadioButton();         radioButton.Text = "Text " + i.ToString();         cell.Controls.Add(radioButton);         row.Cells.Add(cell);     }     table1.Rows.Add(row); }
