You cannot.
However, you could create a nullable int
If a type is not already nullable, you can create a nullable version by adding a question mark onto the end of the name of the type.
int? myNullableInt = null;

I have a grid view control that is defined by data binding.
One of the columns has a really long value so i want to set that the value inside it will jump a line after something like 30 letters. I tried to use the event DataBound to change the column style after the data binding but for some reason it looks like it didn't enter the event and nothing changed.
Does anyone have an idea on how to do what I need or can tell me what went wrong with the way I tried to do it?

It would shurely help if you post your code.
What did you check in the OnRowDataBound-event?
Did you check this if the row was a DataRow?
i.e.:
if (e.Row.RowType.Equals(DataControlRowType.DataRow))
{
}

|
|

Which means that SMTP server is not running. Start the SMTP server, so that it will send from queue folder.

Hi buddy, i guess there are some problems on the settings of the SMTP Virtual Server when you said failure to send a mail.
I suggest you should check the settings of the SMTP Virtual Server as fellowing steps:
1) Open [Properties]->[Access]->[Relay...].
2) Check on [Only the list below] and add the IP address 127.0.0.1 on the dialog "Relay Restrictions".
3) Open [Properties]->[Messages], then enlarge the size of "Limit message size to" to send a bigger attachment with a mail.
Hope this will be helpful to you.

PS there is also a proxy server in between

If you test with Firefox/Firebug, you can step into the code and see what is happening. I don't like the ASP.NET AJAX library because it leaves you with issues like that, I prefer to actually use AJAX.

I think it was that FireFox is easier to use for debugging.

Have you checked your server side code - are you actually rebinding this properly, does the datasource get set correctly?
|
|
|
|
|
Yip. Here is waht happens. The treeview builds fine the first time when the page is loaded. Then when the timer fires the treeview dissapears. Same code is used for both the Page_Load event and the Tick event. My logic tells me that it is not the code it is something else

A better way is to save the UrlReferrer to a named session i.e. Session["YourPageUrlReferrer"] = Request.UrlReferrer.ToString(). When you want to go back the previous page, you can use the value stored in the session i.e. string urlReferrer = this.Session["YourPageUrlReferrer"].ToString().
