Have Problem Embeding Radio Buttons In A Table Cell

Am writing a program in ASP.Net that warrants that I should embede more than one Radion Buttons into table cell and later control it programatically. I wrote the code below but it wasnt displaying the radio Button, I later used HTML control(Radio) It displayed but I cannot programatically control it and moreso error on the onclick event.


Plz help me study the code and tell me what is wrong.


        Dim K As Long
       Dim iFieldCount as integer =3

for k=1 to 10
               

            Dim oRow1 As New TableRow()
            For x = 0 To (iFieldCount )
                Dim oCell As New TableCell()
                               
                             
            oCell.Text ="<asp:RadioButton ID='RadioButton" & trim(str(k))  &  trim(str(x)) & "' runat='server'  OnClick='ShowUrself'/>"
                               
                       oRow1.Cells.Add(oCell)
            Next
           
            tblExample.Rows.Add(oRow1)
       
           
        next

Sub ShowUrself (Sender as object, E As EventArgs)
' Can do things here
end sub
