The row doesn't highlight on click because you have not told it to do so. You must add some JavaScript to the row element that handles the onClick event and highlights the row as desired.

in .NET 3.5, Ajax is integragated with the webproject but in .NET 2.0, one need to install the ajax extensions and tool kit if want to use.

you can get the extension from here

hi guys. i want to store value in session to keep it between postbacks. after page is changed i don't need value anymore. is there a way to kill session on current page i am, before redirect (changing url)? i dont want to use ViewState.

void Page_Load()
{
    if(!Page.IsPostBack)
    {
       Session["something"] = true
    }
}
void Page_LoadComplete()
{
     //i need this value between postbacks, but dont want to init it every time
     bool something = Session["something"] as bool;
}
/*
i would like to have something like this
void Page_IsChangedOrRedirected()
{
     Session["something"] = null;
}
*/

You can use

Session.Remove("something");

wherever you want.

Am I understanding you correctly, that you need the value to be part of the session as long as the user is using PostBack, but on a new page load, the session value should be empty?
If that is the case, then you can do this simply like this

void Page_Load()
{
    if(!Page.IsPostBack)
    {
        Session["something"] = true;
    }
    else
    {
        Session["something"] = false;
    }
}

Interview task - what can I expect?

Hi, I have a interview next week and I have been told there is a test to:

"The technical test will involve creating a SQL server database, importing data into the database and writing a programme to extract data using SQL and C# and ASP.NET."

Can anybody who has set or taken something similar please advise what I can expect here?

I am thinking the data may be in a flat file or excel spreadsheet and I would need to use DTS or import it via the SQL Server wizard? The extract bit, I would guess is either displaying the results on a web page or writing code to extract it to an excel file?

Thanks in advance!

Well you haven't told for what post you're going to attend interview and with how much experiance.

If the interview having purely dependency on SQL Db and IMPORT and EXPORT with it, Then It could be of SSRS ( Reporting service ),SSIS ( Integration service) or It could be of data synchronization services.

It is not really easy to tell that what questions will be asked in the interview. This completely depends on the person who is taking the interview. You can get some idea if you know that what kind applications that organization is building. Normally you can expect questions on the basic concepts of oops and their implementation and other stuffs. Besides they also give you some scenario and ask you to give your opinion on it. This is just to know your approach on the problem.

Don't use outdated terms like DTS. The current tool would be SSIS. If you don't plan on using entity framework in your sample or something else other than straight ADO.Net in the page, make sure you let them know that a real application would probably use some framework like nHibernate in a real data access layer and not just simple ADO.Net directly in the pages themselves.

Unless of course you personally would normally use ADO.Net directly in the pages. If so, slap yourself with a trout hourly until you learn all about separation of concerns and proper object oriented design.

Linq-Sql DateTime?

Hi guys,
Iam trying to update a nullable datetime field in my database using linq-sql.
What ever casting method i have tried i keep getting an error:

"Specified cast is not valid."
Does anyone know how to update a nullable DateTime? field using Linq-Sql? please help me.
I have tried:

myVar.dateredeemed = DateTime.Parse("2010-12-03"); //still throws the same error
myVar.dateredeemed = (DateTime?)dateTime; //still throws the same error
myVar.dateredeemed = DateTime.Now; //still throws the same error

I don't really what else i can try because all of the above won't work.
Please help me...

Re: Linq-Sql DateTime?

Keith Barrow2-Dec-10 22:40

None of this screams LINQ-to-SQL. Your code should work is myVar.dateredeemed is of type DateTime? if not, that is the source of your problem.

This code works:

DateTime? foo;
foo = DateTime.Now;

However, you should be wary of this:

myVar.dateredeemed = DateTime.Parse("2010-12-03")

For two reasons:

If the string really comes from user input, they can enter an incorrect value you need to decide whether this should be null or whether the user *must* enter a valid date. Whichever is the correct strategy, incorrect input will throw an error.
Can the user enter no date, (i.e. "")? If so you code will not result in null

Finally, I'd say one more thing: If you have luxury of changing the database, avoid nulls (especially in databases) like the plague. You end up with problems similar to the one you have here, potential null reference exceptions, and they make coding SQL harder too. That's not to say don't ever use nulls, but you should think several times before using nullable columns. Personally, I'd use one of the SQL min/max dates in place of null to register "unknown", (a bit like replacing and unknown [null] string with "") but others will disagree. A null date (to represent a date not set yet) is one of the few places I think a null column might be pukka. </rant> - Sorry I didn't mean to go on like this Smile | :)

File upload doesn't work under UpdatePanel ByDefault. you need to set PostBackTrigger in <Triggers> Section of UpdatePanel by which you can force a complete PostBack.

Actually in my form i had a ultrawebgrid and a template column as button,

when click the button by client side the value ll be assign to the fileupload control and

when i click the upload button the file should be uploaded .

My ultrawebgrid and upload button is inside refresh panel and fileupload is outside the refreshpanel.
