Hi,
How to raise Session_End event at Global.asax if I use SQLServer for session state. I want to clean up some data when user click X at their browser or if their session is expired.

Any help will be appreciate.

Thanks

Then you need to use the Javascript onunload event and make a request to the server telling it that the user is leaving the page. You can't use session state to catch when the user is leaving, as the server session doesn't end when the browser is closed.

Despite everything, the person most likely to be fooling you next is yourself.

Custom ExpressionBuilder + ParseControl. No Joy? [modified]

mgkr23-Oct-08 4:17

Using a custom ExpressionBuilder doesnt seem to work with ParseControl (dynamically adding controls, that are using the custom ExpressionBuilder)

Works fine with the build-in Resources ExpressionBuilder though.

Anyone have a solution/workaround for this?
Or even an explanation for why it doesnt work.

Example

protected void Page_Load(object sender, EventArgs e) {
  string s = (@"
    <hr />
    1: <asp:Label ID=""Label1"" Text=""<%$ Resources:language, Greeting %>"" runat=""server"" />
    <br />
    2: <asp:Label ID=""Label2"" Text=""<%$ IHLPResource:Greeting %>"" runat=""server"" />
    <hr />
  ");

  Control ctrl = ParseControl(s);
  Page.Form.Controls.Add(ctrl);
}

1: Gets rendered just fine, while 2: fails (no error, the value just doesnt get rendered)
ie. the output is:

1: Hi 
2:

(2: should say "\\\Output from custom ExpressionBuilder///" - See code below)

If I simply add the above to the aspx page, it works fine (ie. my custom ExpressionBuilder is not the cause of failure)

How can I solve this problem.

lnkAddTraveler.CommandName = "Hotel," + dtHotelInfo.Rows[i]["Id"].ToString() + "," + dtHotelInfo.Rows[i]["HotelID"].ToString();

private void lnkAddTraveller_Command(object sender, CommandEventArgs e)
{
//Code here
}

This will give you all the dates in the current week - you will need to adfjust it depending on what your starting day is, this assumes Monday.

DateTime curr;
DateTime start = DateTime.Now.AddDays((int)DateTime.Now.DayOfWeek * -1);
for (int c = 1; c < 8; c++)
{
      curr = start.AddDays(c);
}

To which exchange server do you want to connect? Exchage server 2003 or 2007.
if your are trying to access Exchange 2007 Server, then you can able to do it easily. becuase Exchange 2007 provide Webservices for same (EWS ) . But its not possible using Exchange 2003, because it does not provide any such API's
Check This[^]

Having looked at a couple of your questions here, i'd suggest maybe a book on ASP.net, or some tutorials (see www.asp.net).

This is fairly fundamental stuff, you'll need a decent grounding in it for any ASP.net development.

Calender Control

I have written the following code on selectionchanged event of calender control.SelectedDatesCollection theDates = Calendar1.SelectedDates;
foreach (DateTime selectedDate in theDates)

txtsun.Text = theDates[0].ToString("MM/dd/yyyy");
txtmon.Text = theDates[1].ToString("MM/dd/yyyy");
txttue.Text = theDates[2].ToString("MM/dd/yyyy");
txtwed.Text = theDates[3].ToString("MM/dd/yyyy");
txtthru.Text = theDates[4].ToString("MM/dd/yyyy");
txtfri.Text = theDates[5].ToString("MM/dd/yyyy");
txtsat.Text = theDates[6].ToString("MM/dd/yyyy");
It is working fine.

But i want the same output on page_load event also.how can i get this. can anyone help me.

I don't quite understand - you want the values selected by a user in a calendar control, but in the page load event?
