Hi all

I m using Asp.net(Vb) and When the user wants to delete the item i'll have to show a Message Box with Ok and Cancel.
In Vb.net we can use Msgbox() but in asp.net it gives error so i'll have to use javascript' alert function() for it but how can i use it in my code file abc.vb not in the abc.aspx(source file).
And if i use it in source file then how can i access the result(ok or canel) in my code file' button click event???

 Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click<br />
        Dim result As MsgBoxResult<br />
        result = MsgBox("Do you want to delete the record permanantely?", MsgBoxStyle.OkCancel)<br />
<br />
        If result = MsgBoxResult.Ok Then<br />
            Sql = "Delete from items where userid=" & Session("userid") & " and itemid=" + itemid.ToString<br />
            cmd = New SqlCommand(Sql, cnn)<br />
            cmd.CommandType = CommandType.Text<br />
<br />
            Me.cnn.Open()<br />
            Me.cmd.ExecuteNonQuery()<br />
            Me.cnn.Close()<br />
<br />
            Me.add_record()<br />
        End If<br />
    End Sub

Thanks with anticipation...

In ASP.Net u can use Javascript confirm for this purpose.
based on return value of confirm u can delete the record.

u use VB as a code behind language.
in Inline code U can use Javascript.

for ex.

Inline code
----------
script>
function check()
{
if(confirm("Do u want to delete"))
return true;
else
return false;
}
/script>
asp:button text="delete" id="b1" onclick="b1_click" onclientclick="return check()" /

No, that just plain does not work. Buy a book on ASP.NET and read it, please.

It looks to me like what you want to do, is that have the button that does the deleting, call some script on the cleint to prompt the user, and only do the postback ( and therefore the delete ), if they click yes.

For your kind information its not my home work its my project and i m not a student, i m a software engineer and have experience of more than 1 year in vb.net and now i wanna work in asp.net that's why is said that i m newbiew to asp.net.

I respect all the senior person in codeproject boz of their helping nature and once you also helped me to solve my problem and i m still greatful for that but that doesn't means u can say anything to me.
Its not the right way to talk someone being a senior person
Any ways let it go.........

I'm sorry to say that you've proven my point. You've used VB.NET for one year ? A computer science course takes 3-4 years, and you list no other languages, how much of the one year of your life that you've known how to write a bit of code, were you paid for it ? You're obvioulsy learning ASP.NET by taking paid projects in it, that is just plain disgusting, but not surprising, given the bad experiences I've had with Indian outsourcing companies.

As far as I can see, a lot of outsourcing firms hire people who have no idea, and then expect the people in the West who are losing their jobs as a result, to do their work, on the basis of their inability and unwillingness to buy books, use google, and spend some time learning before they expect to be paid for their efforts.

I am always happy to help people, that's why I am here. But, the direction our industry is taking is upsetting to me. I take solace in the fact that outsourcing companies are still offering poor quality of code and inexperienced workers, I feel sure I'm not going to see my job threatened, but I feel equally sure that in the eyes of those stupid enough to use outsourcing companies, what I do is being devalued.

You refer to me as a senior person. I can tell you for sure, that if I interviewed someone for an ASP.NET position, and they didn't know the things you obviously didn't know from your first post, I would not even consider them. I would probably tell war stories about the person who needed to be in college, not trying to be paid for their efforts. But, you are not alone. The double tragedy is that people where I live can't find good developers, I know of many companies that cannot find a skilled dev because people have left computer science, wrongly thinking there would be no work. I have recently been paid $80 an hour by a company that can't find skilled worker locally, and have tried to outsource briefly and found just what a nightmare it is for all but the most menial tasks. That's $166,000 a year, less than I earn, but 3 times what the average developer used to make around here.

So, please don't tell me what the right way is to talk. I've helped you, and I've also tried to make you realise just how far you have to go before you can hold your head up high when asking to be paid for writing ASP.NET code. My desire in doing this is to inspire you to actually rise above the standards of those around you, and do some study, to become an actual software engineer, able to do research, able to understand the frameworks you are using, able to do your job without bringing your most basic questions here. I know that often I don't tell people what they want to hear around here, but I always try to tell them what they need to hear, if they are to stand any chance of making it as developers. I'm trying to help people, not win their friendship. It's sad that nowadays I have to choose between those two things sometimes.

Lets try this one more time. After reading this response go back and look over the responses you've already been given.

The way to achieve what you want in ASP is to attach a client side confirm box which stops postback if the user clicks "Cancel". To stop a postback from a link, or button, you return false in the OnClientClick. handiliy, the javascript confirm returns false if the user click "Cancel".

Hence: OnClientClick="return confirm('Are you sure you wish to delete this item')"

Finally, if you need to do this within a grid with a delete button/link the idea is to use FindControl to get a reference to the link/button and append the relevant OnClientClick.

If any of this is hard for you to understand I have given you a plethora of keywords to search google for.
