Subscribing to event from Template Column

I have an ascx control in the ItemTemplate of a Template Column in a
datagrid. The control (myControl) raises an event.

I'm trying to figure out how I can subscribe to the event. It can't be done
at design time because myControl is not one of the recognized controls. At
run time I would expect to use AddHandler but I can't seem to reference
myControl.

How can I subscribe to the event?

Thanks,
THi Tina,

If your control is simply a composite control that is placed declaratively
on the page at design time then you can add the event handler within the ascx
codebehind file.

Alternatively, you can use event delegates to expose events out of your ascx
to its NamingContainer (in your case it is the DataGridItem) as I did in this
example: http://www.societopia.net/Samples/D...tDelegates.aspx

I guess I'm going to have to learn c# if for nothing other than to follow
the examples...

in VB to handle an event we ....
AddHandler myControl.TimerEvent, AddressOf me.HandleTimerEvent
..
..
Protected Sub HandleTimerEvent(byval o as Object, byval e as TimerArgs)
.. code to handle event is here...
end sub

How would the AddHandler code look in the case where myControl is in
DataGrid1?

Hi Tina,

For you to be able to handle an event (e.g. TimerEvent) raised by your
control it has to define a delegate method that you can use when placing that
control in the DataGrid. If it does that then you can handle that event by
specifying a function for the delegate method (e.g. if your event is named
TimerEvent, you should design your control to expose a method named
OnTimerEvent)

I created here
http://www.societopia.net/Samples/D...rolsEvents.aspx a sample
in VB.Net where I designed a user control (in an ascx file) that raises an
event (I called it CustomEvent1) by exposing a delegate method called
"OnCustomEvent1". I then included that control in a TemplateColumn on the
DataGrid and wired the delegate function named OnCustomEvents to an event
handler within the page class codebehind.

subtracting two dates to get number of days between

How would i take two dates startdate and enddate and subtract startdate from
enddate to figure the number of days between the two? thanks["Followup-To:" header set to microsoft.public.dotnet.languages.vb.]

Dim Difference As TimeSpan = enddate.Subtract(startdate)
Console.WriteLine(Difference.Days)

neverminde :)

If DateDiff(DateInterval.Day, dbReader("sectionedited"), Now.Date) <= 30
Then

Not sure what language you want, but the VB isn't much differen that this C#

DateTime d1, d2; // Make sure you assign these first

TimeSpan ts = d1-d2;

int days = ts.Days;

((start.Ticks - end.Ticks) / TimeSpan.TicksPerHour) /24;

System.DateTime includes a Subtract method, which will do exactly this. In
C#, you can also use the - operator.

when i do this

Dim diffNUmb As Integer = DateDiff(DateInterval.day,
dbReader.GetDateTime(dbReader.GetOrdinal("sectionedited")), Now())

the sectionedited attribute of the table in the dbreader being a datetime
with a date/time of #10/19/2003 12:00:00 AM# in it and i run it, every time
it will return 0 as the diffrence in days even though i change the month and
day in the fixed date... why would it do this? thanks
