Thanks Olaf for the suggestion. Actually what I want is when the
LinkButton whose Text is '1' is clicked, this LinkButton should get
disabled so that it becomes "unclickable". Next if the LinkButton with
the Text, say, '4' is clicked, then this LinkButton should get disabled
& at the same time, the LinkButton with the Text '1' which was disabled
just before the LinkButton with the Text '4' was clicked should again
get enabled. I already tried what you have suggested prior to getting
your response like this
For i = 1 to 5
lnkBut = New LinkButton
lnkBut.ID = "lnkBut" & i
lnkBut.Text = i.ToString & " "
lnkBut.CommandName = i
AddHandler lnkBut.Command, AddressOf BtnCommand
pnlLinks.Controls.Add(lnkBut)
Next
Sub BtnCommand(obj As Object, ea As CommandEventArgs)
Dim iPageNum As Integer
Dim lnkBut As New LinkButton
iPageNum = CInt(ea.CommandName)
lnkBut = CType(obj, LinkButton)
Response.Write("You clicked Link" & lnkBut.Text)
If (iPageNum = lnkBut.Text) Then
lnkBut.Enabled = False
Else
lnkBut.Enabled = True
End If
End Sub
Assume that there are 5 LinkButtons - 1 2 3 4 5. When I click '4',
then '4' gets disabled i.e. it becomes unclickable & the text 'You
clicked Link4' appears but next if I click, say, '1', then '1' does get
disabled & the text 'You clicked Link1' appears but at the same time,
'4' still remains disabled where as I want '4' to get enabled under
such circumstances.
Can you suggest some workaround to the above code so as to ensure that
only one LinkButton remains disabled at any time when any of the
LinkButtons is clicked?
Thanks once again.

Consider the following code which creates LinkButtons dynamically:
For i = 1 to 5
lnkBut = New LinkButton
lnkBut.ID = "lnkBut" & i
lnkBut.Text = i.ToString & " "
lnkBut.CommandName = i
pnlLinks.Controls.Add(lnkBut)
Next
The above code will display 5 LinkButtons in the Panel named 'pnlLinks'
like this
1 2 3 4 5
When any of the LinkButtons is clicked, the page gets posted.
After postback, how do I find out which of the 5 LinkButtons has been
clicked by the user in the Page_Load sub?
you can't - use the .Command-event of your button. In order to have that
event be fired, create a handler, i.e.:
Protected Sub lnkBut_Command(ByVal sender As Object, _
ByVal e As System.Web.UI.WebControls.CommandEventArgs)
'Your code here, i.e.:
Response.Write(e.CommandName)
End Sub
And, when creating your controls, add that handler:
For i = 1 to 5
'...
AddHandler lngBut.Command, AddressOf lnkBut_Command
lnkBut.CommandName = i
pnlLinks.Controls.Add(lnkBut)
Next
Cheers,
Olaf
