I have a DataList control with an EditTemplate. Three of the controls in
this template include a Calendar, a Button with CommandName="up date", and a
Button with CommandName="ca ncel". Whenever I click one of these controls,
the DataList replaces the EditTemplate with the ItemTemplate. I think this
is because the method I wrote which performs the databinding is getting
called, but I don't know why or where it is getting called from. It does not
get called from my Page_Load method and I do not have an ItemCommand event
handler, so I don't know where to start testing for it. I tested to see if
my UpdateCommand event is getting called when I click the Button with
CommandName="up date" by assigning some text to a Label control, so I know
that it is never getting called. What could be causing my problem? Any help
would be appreciated. Thanks.

Nathan,
Make certain that your DataList control has it's viewstate property set to
true and then, wherever in your code you are binding the DataList, wrap that
code in:
If Not IsPostBack Then
'---Bind your DataList here.
End If
I don't know exactly where you are doing your databinding, but from what you
describe I think you have identified your problem correctly. Your DataList
is getting re-bound on postback.
By the way, please don't post to more than one newsgroup at a time...

It's called from the Button's OnCommand event handler. The OnCommand is bubbled
up thru the part control hierarchy so child controls like the button can
send commands up to parent controls.

My DataList's EnableViewState property is set to True. I have tried wrapping
my binding code in an If Not IsPostBack Then statement like you said, but
that causes the binding to not occur at other times when it does need to
happen. I have a method that contains my binding code which I call in my
Page_Init method as well as after I make any changes to the database I use
as my datasource. This method is as follows:
Private Sub RefreshEvents()
Dim events As New DataSet
Dim myconnection As New
OracleConnectio n(System.Config uration.Configu rationSettings. AppSettings("co nnectionString" ))
Dim cmdselect As New OracleCommand(" SELECT * FROM eventlist WHERE
eventdate<TO_DA TE('" & Date.Now.ToShor tDateString() & "','MM/DD/YYYY')",
myconnection)
Dim cmddelete As New OracleCommand(" ", myconnection)
Dim eventsadapter As New OracleDataAdapt er(cmdselect)
'Delete any past events and the people who registered for them
eventsadapter.F ill(events, "eventlist" )
If events.Tables(" eventlist").Row s.Count <> 0 Then
For Each pastevent As DataRow In events.Tables(" eventlist").Row s
cmddelete.Comma ndText = "DELETE FROM registered WHERE eventid=" &
pastevent.Item( "eventid")
myconnection.Op en()
cmddelete.Execu teNonQuery()
cmddelete.Comma ndText = "DELETE FROM eventlist WHERE eventid=" &

If pastevent.Item( "details") <> "" AndAlso
System.IO.File. Exists(Server.M apPath("eventde tails/" &
pastevent.Item( "details")) ) Then
System.IO.File. Delete(Server.M apPath("eventde tails/" &
pastevent.Item( "details")) )
Next
End If
'Fill DataSet with all remaining events
events.Clear()
cmdselect.Comma ndText = "SELECT * FROM eventlist ORDER BY eventdate"
eventsadapter.S electCommand = cmdselect
eventsadapter.F ill(events, "eventlist" )
datEditEvents.D ataSource = events
datEditEvents.D ataBind()

ddlDeleteEvents .Items.Add(New

I think you misunderstood what I meant. If I were to use the If Then like
you said, the If Then would have to go inside my RefreshEvents() method,
since that is the only place that I know is getting called during the
"undesired" databinding. However, if I did that, it would affect the
databinding when I don't want it to just like when I had the problem before.
If I knew where the "undesired" databinding was being called from (in other
words, what method calls RefreshEvents() when I don't want it to) I could
put the If Then there, but I don't know where that is. Another solution, if
it exists, would be to use an If Then with a condition based on what method
was calling it. Any ideas? Thanks.

I would like to set a breakpoint in Visual Studio to find the undesired
call, but unfortunately the site is on a remote server and according to the
person in charge of the server (who is also the person who taught me
ASP.NET) the server's ability to do debugging remotely has been turned off.

Hmmmm,
That's going to make it hard to identify...
What type of system are you on? I develop all my code on a Windows XP Pro
system running iis locally, then I deploy the code to a development server
for testing, Staging for more real-world testing, and finally production.
Can you set up your project to run locally and debug there?
Otherwise you're going to have to just really look at your code carefully...

You've got the solution at hand. You need to identify the undesired
call(s) to RefreshEvents() and put the If Then there.
That's really the only way to do it. If you're using Visual Studio now is
the time to set a breakpoint and see exactly what your code is doing...

"Nathan Sokalski" <nj********@hot mail.com> wrote in message
news:%2******** ********@TK2MSF TNGP09.phx.gbl. ..I think you misunderstood what I meant. If I were to use the If Then like
you said, the If Then would have to go inside my RefreshEvents() method,
since that is the only place that I know is getting called during the
"undesired " databinding. However, if I did that, it would affect the
databindin g when I don't want it to just like when I had the problem
before. If I knew where the "undesired" databinding was being called from
(in other words, what method calls RefreshEvents() when I don't want it
to) I could put the If Then there, but I don't know where that is.
Another solution, if it exists, would be to use an If Then with a
condition based on what method was calling it. Any ideas? Thanks.

Leave the if then and then call the binding code when you need to from
those methods.
