The window.onbeforeunload event will catch it. But this event will also be fired if you postback the web page. Therefore you cannot differentiate whether the browser is closed or the web page is submitted using this event.

As i said in my answer, the onunload and onbeforeunload will be fired whenever the browser is closed or the web page is submitted to the server. Therefore you cannot differentiate between these two events. Therefore it is not advisable to handle this event.

Hi Prasadbuddhika,.. this is a property of session that session will automatically expire with browser close. Means if u close any browser window, all session will automatically expire.

Hi
I am trying to implement OpenId and facebook connect login for our site. I found there RPX API which supports login from variuos providers. I found only uservoice.com which implemented with RPX API, my question is whether do we get password to store in our database for next time login if the user wants to use our site login form.
Any ideas please!!!!!!!!

Hello,
Good question. With RPX, relying party sites that have enabled third party logins do not store a user password. The user is redirected back to his/her preferred identity provider's site to authenticate, and while a rich set of profile data can be passed back to a relying party site with that user's consent, the password stays with the provider.
This enhances the overall security of OpenID as a technology and as a standard, since a user's password must no longer be exposed out in the wild on sites with potentially unencrypted user databases.
For return logins, RPX stores a cookie to remember a user's preferred provider, and displays that provider's button as the primary option to sign-in. This makes the return visit sign-in process as easy as a single click.
For more information on RPX, you can check out our technical documentation at http://rpxnow.com/docs, visit our developer wiki at http://rpxwiki.com or email us at supportATrpxnowDOTcom.
One more thing - a relying party site also has the option of prompting users to create a username/password when signing-in with a third party account for the first time, as a backup if necessary.

i want to convert sql data to Text.txt Format , How it Posible?
|
|
|
|

First, this question is not related to asp.net.
If you want to convert SQL Server data into text format, you can use export/import feature available in the SQL Server Management Studio.

Hi all!!!
I have a problem wich conversion format DateTime.
I create AjaxCalendar UserControl, an use it in my page, and I have a conversion format DateTime:
<br />
protected void AjaxCalendar_DataBinding(object sender, EventArgs e) {<br />
try {<br />
DateTime time = DateTime.Parse(TextDate.Text, new CultureInfo("en-GB"));<br />
}<br />
catch (Exception) {<br />
TextDate.Text = string.Empty;<br />
return;<br />
}<br />
}<br />
and asp code of User Control:
<asp:TextBox ID="TextDate" runat="server" Width="70px" />
<Ajax:CalendarExtender ID="AjaxCalendar" runat="server" TargetControlID="TextDate" Format="dd/MM/yyyy" OnLoad="AjaxCalendar_DataBinding"/>
I load from database and add to database datatime from this control. When I use Visual Studio (I use Visual Studio 2008) this conversion work fine, but when i put my project page on IIS or on Server this conversion not work, and i obtain "String.Empty".
If I block this code I obtain data in format MM/dd/yyyy. In Regional Options i have selected format English and stat United Kingdom.
I write implicit conversion in this Mode ...ToString("dd/MM/yyyy") looks fine, but when i wont to add data in database with datetime i obtain error on dateTime.
Help me, PLEASE to create a conversion function or else, for work in IIS, or on Server.

I have a gridview with autogeneratecolumn false.I have bind it with a data table dt.In dt there is a column named as "status" whose data type i bit.that means status can take either 0 or1.in gridview this column shows true or false.
I want to show "Read" and "Unread" for 0,1 respectively.
How can I do???
plz..help...
|
|
|
|
|
In GridView1_RowDataBound(),
try this,
if (e.Row.Cells[1].Text == "0")
{
e.Row.Cells[1].Text = "Read";
}
|
|
|
|
|
Use the GridView RowDataBound Event Delegate to change the value of one cell.
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)<br />
{<br />
e.Row.Cells[0].Text = e.Row.Cells[0].Text == "0" ? "Unread" : "Read";<br />
}
Happy Coding...

You can also use case in query at time of retrieving data from database :-
For Example:-
case status when '0' then 'Unread' else 'Read' end as status
