nested datalist question

[liunx]

I have a parent datalist

inside the parent <selecteditemtemplate> are two child datalists

I can click on a linkbutton in the first child datalist ( it makes child 2 datalist visible)

once the child 2 datalist is visible, I click on a linkbutton inside child 2 and it (for some reason) makes the parent <selectedItemTemplate> close.


I cannot figure out for the life of me why:

the parent <selecteditemtemplate> doesnt close if I click a link in child 1
but parent <selecteditemtemplate> closes if I click a link in child 2?

Hope someone can Help, it would be much appreciated!!


heres the code:

Sub selectedsub1( sender As Object, e As DataListCommandEventArgs )

If e.CommandName = "clickedsub1" Then
Dim listsub1 as string = ctype(e.item.findcontrol("listsub1"), label).text
ctype(e.item.findcontrol("Sub2DL"), datalist).visible = true
ctype(e.item.findcontrol("sub1butt"), linkbutton).visible = false
ctype(e.item.findcontrol("sub1butt2"), linkbutton).visible = true
ctype(e.item.findcontrol("Sub1Folder"), image).ImageUrl="../Images/openfolder.jpg"
sub2.text = ""
sub1.text = listsub1

End If

If e.CommandName = "clicked2sub1" Then
ctype(e.item.findcontrol("Sub2DL"), datalist).visible = false
ctype(e.item.findcontrol("sub1butt"), linkbutton).visible = true
ctype(e.item.findcontrol("sub1butt2"), linkbutton).visible = false
ctype(e.item.findcontrol("Sub1Folder"), image).ImageUrl="../Images/closedfolder.jpg"
sub2.text = ""
sub1.text = ""
End If

If e.CommandName = "clickedsub2" Then
Dim listsub2 as string = ctype(e.item.findcontrol("listsub2"), label).text
ctype(e.item.findcontrol("sub2butt"), linkbutton).visible = false
ctype(e.item.findcontrol("sub2butt2"), linkbutton).visible = true
ctype(e.item.findcontrol("Sub2Folder"), image).ImageUrl="../Images/openfolder.jpg"
sub2.text = listsub2
End If

If e.CommandName = "clicked2sub2" Then
Dim listsub2 as string = ctype(e.item.findcontrol("listsub2"), label).text
ctype(e.item.findcontrol("sub2butt"), linkbutton).visible = true
ctype(e.item.findcontrol("sub2butt2"), linkbutton).visible = false
ctype(e.item.findcontrol("Sub2Folder"), image).ImageUrl="../Images/closedfolder.jpg"
sub2.text = listsub2
End If

End Sub
