Hi All,

Working in ASP.Net.

I have some radio buttons that I create with a For..Next loop in my code-behind file. What I want to know is does anyone know how to set the oncheckedchange event in the code behind file to run a procedure when a different radio button is checked?

I know how to do this in the form design, but I can't find anywhere how to in the code behind file. I am working in VB.Net, so please only post in this language. Thanks in advance.

You need to create a handler in your code behind that conforms to the standard event handler signature, then when you build the radio button you add a handler to the oncheckchanged event (or any other for that matter).

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    'Put user code to initialize the page here
    Dim i As Integer
    Dim optRadioButton As RadioButton
    For i = 0 To 9
        optRadioButton = New RadioButton()
        optRadioButton.ID = "optRadioButton" & i.ToString
        optRadioButton.Text = "Radio button " & i.ToString
        optRadioButton.GroupName = "optRadioButton"
        optRadioButton.AutoPostBack = True
        AddHandler optRadioButton.CheckedChanged, AddressOf optRadioButton_onCheckedChanged
        plcRadios.Controls.Add(optRadioButton)
    Next
End Sub

Private Sub optRadioButton_onCheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs)
    Response.Write("you clicked on " & CType(sender, RadioButton).Text)
End Sub

Exactly what I needed! Thanks!

i cant get the event to fire as described above

 Dim radioselectCell As New HtmlTableCell
 Dim selectrateRadio As New RadioButton

selectrateRadio.ID = i
selectrateRadio.GroupName = "selectrateRadio"
selectrateRadio.AutoPostBack = True
AddHandler selectrateRadio.CheckedChanged, AddressOf selectrateRadio_onCheckedChanged
radioselectCell.Controls.Add(selectrateRadio)

Private Sub selectrateRadio_onCheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs)
        Response.Write("you clicked on " & CType(sender, RadioButton).Text)
    End Sub

any ideas ? thanks in advance
