Display selected items of a dynamically created checkboxlist

I think that you'll have to search your control first, and than use that control

Dim control As Control
For Each control In Me.Controls
    If TypeOf (control) Is CheckBoxList And Control.Name = "Yourdynamicnamehere" Then
    Dim myCheckBoxList  As CheckBoxList = control
     If (myCheckBoxList .SelectedItem <> "") Then
            Dim Entry As Object
            For Each Entry In myCheckBoxList .CheckedItems
                MessageBox.Show(Entry.ToString())
            Next
        Else
            MessageBox.Show("You must select an item")
        End If      
   end if
next

Dim chkSelect As checkbox
 For i = 0 To dg.Items.Count - 1
                chkSelect = Me.dg.Items(i).FindControl("chkSelect")
                If chkSelect.Checked Then
                     _doStuff() 
                else
                     _doOtherStuff
                end if
 next i'dg = datagrid
Dim chkSelect As <strong class="highlight">checkbox</strong>
 For i = 0 To dg.Items.Count - 1
                chkSelect = Me.dg.Items(i).FindControl("chkSelect")

thanks for your post!
Im not sure i understand however?
i have altered my code as such....
-------------------------------------------------------------------------------------------------
Dim control As Control
        For Each control In Me.Controls
            If TypeOf (control) Is CheckBoxList = "CheckBoxListSecondary2" Then
                Dim myCheckBoxList As CheckBoxList = CheckBoxListSecondary2
                If (myCheckBoxList.SelectedItem.Value <> "") Then
                    Dim Entry As Object
                    For Each Entry In myCheckBoxList.SelectedItem.Value
                        lblShow2.Text = (Entry.ToString())
                    Next
                Else
                    lblShow2.Text = ("You must select an item")
                End If
            End If
        Next
-----------------------------------------------------------------------------------------------------------------------
CheckBoxListSecondary2 is my dynamically created checkbox list, and lblShow is the label...
however when i run this im getting an error saying that the input string was not in correct format?

Did you try this:

Dim chkSelect As checkbox
 For i = 0 To dg.Items.Count - 1
                chkSelect = Me.dg.Items(i).FindControl("CheckBoxListSecondary2")
                If chkSelect.Checked Then
                     lblShow2.Text = chkSelect.SelectedText
                else
                     _doOtherStuff
                end if
 next i

Im playing around with these snippets of code you gave me but still having no joy!
im very much a novice programmer, so if there is any explanation perhaps in lehmann's terms it would be very helpful!
many thanks again!

Thats great, i'll have a read.
Thanks very much for your help!!!

Ive found the problem!
The code could not loop as it was in the page load event, for some reason!!
when i moved it to the page Init event it works fine!!
thank you for your help again!
