Question

I have generated some questions from a dataset with textboxes next to them in a dynamically generated html table. I have 5 questions and 5 textboxes.
So, i need to get back the values of some textboxes.

I am looping through the dataset and adding a series of questions with textboxes next to them. However, do i need to generate some unique ID to each textbox?

private void GenerateTable(int colsCount, int rowsCount, DataSet ds, DataSet ds2)
{
    if (!IsPostBack)
    {
        int counter = 0;

        List<TableRow> tableRowList = new List<TableRow>();
        List<TableCell> tableCellList = new List<TableCell>();
        List<Control> controlsList = new List<Control>();

        foreach (DataTable dataTable in ds.Tables)
        {
            foreach (DataRow dataRow in dataTable.Rows)
            {
                TableRow tableRow = new TableRow();
                TableCell tableCell = new TableCell();
                TableCell tableCell2 = new TableCell();
                TextBox textbox = new TextBox();
                //textbox.ID = "TextBoxID";

                TableRow tableRow2 = new TableRow();
                TableCell tableCel2 = new TableCell();

                tableCell.Text = dataRow["QUESTIONTEXT"].ToString();


                if (dataRow["TYPEID"].ToString() == "1")
                {
                    tableCell2.Controls.Add(textbox);
                    controlsList.Add(textbox);
                }


                tableRow.Cells.Add(tableCell);
                tableRow.Cells.Add(tableCell2);
                myTable.Rows.Add(tableRow);

                tableRowList.Add(tableRow);
                tableCellList.Add(tableCell);
                tableCellList.Add(tableCell2);

                counter++;
            }
        }

        //TextBox tb = myTable.FindControl(TextBoxID) as TextBox;

Do I need to generate some unique ID to each textbox?

Yes… id must be unique. a page with more than one element with the same id is invaliid

spec:

id=name [CS]
This attribute assigns a name to an element. This name must be unique in a document.

But if you are not using the id at all you can just not assign id at all…
