Hi I have written code for dynamic generation of textboxes and label.Refer below but i am not getting textbox.text values.It shows error like
Specified argument was out of the range of valid values.Parameter name: index
Code:

protected void ddlanswers_SelectedIndexChanged(object sender, EventArgs e)
        {
            int count = Convert.ToInt32(ddlanswers.SelectedValue.ToString());
            
            for (int i = 0; i < count; i++)
            {
                Label lbl = new Label();
                TextBox txt = new TextBox();
                lbl.Text = "Option " + (i + 1).ToString();
                lbl.ID = "Option" + (i + 1).ToString();
                
                txt.ID = i.ToString();
                TableRow row = new TableRow();
                TableCell cell = new TableCell();
                cell.Controls.Add(lbl);
                row.Cells.Add(cell);
                TableCell cell1 = new TableCell();
                cell1.Controls.Add(txt);
                row.Cells.Add(cell1);
                Table1.Rows.Add(row);            
         }           
        }
protected void btnsavequestion_Click(object sender, EventArgs e)
        {
            int count1 = Convert.ToInt32(ddlanswers.SelectedValue.ToString());             
            for (int i = 0; i < count1; i++)
            {
                TextBox tb = Table1.Rows[i].Cells[1].FindControl(i.ToString()) as TextBox;
     //I m getting error here
//error:Specified argument was out of the range of valid values.Parameter name: index
