I have an input text HTML control (not ASP.NET control) on an ASP.NET page in a content place holder. I am able to execute JavaScript functions from onfocus (to clear the control), and onkeyup (to verify data) events but not from an onchange event.
When the onchange event didn't give expected results I tried an onclick event, and an alert to show the event fired, to verify the JavaScript function was coded correctly and the function operated as expected.
Does anyone know why these other events fire but the onchange event does not fire?
<reason>
Strange as it seems the onchange event was not firing because I also had an onkeyup event on the control. If I remove the onkeyup event the onchange event fires. When I add the onkeyup event back in the onchange event doesn't fire.
Thanks ASP.NET! 
Since I need the onkeyup event for verifying only selective keystrokes are accepted I am left with the task of making an onpropertychange event, which fires on every keystroke, mimic the behavior of the onchange event which only gets fired if the content changed and the focus has moved away from the control.
I cannot use the onblur event because one of the fields presents a calendar control which when displayed fires the onblur event. I have a 98% solution now but it doesn't work for some pretty obscure fringe cases.
I will still have to keep working on this to get to a 100% solution.
</reason>

onchange event fires only when you changed the text and then lost the focus from the textbox.
It will not fire every time you press the key. It will fire only once, for text change in the textbox, after loosing focus.
If you wish to handle event as soon as user types, use on KeyPress event instead.
Hope this will help.

Yes that is the expected behavior but it is not happening.

Hi,
I am working on the C#/.NET application where in i need to get Current Identity value of the table using LINQ. Or else I can use the sql query to get the task done by either using
var num = DataContext.ExecuteCommand("Select IDENT_CURRENT ('table')");
By using this above code, i am getting the value = -1.
or
var num = DataContext.ExecuteQuery(("Select IDENT_CURRENT ('table')");
By using the above code, i am getting an exception "Specified cast is not valid." and the value remains NULL.
Correct me if i am doing something wrong. let me know if there are any better ways to do this task.
Thanks for ur help in advance.

Are you inserting data through Linq with SP OR adding object?

I am not inserting any data. I just want to have the Current Identity value of the table. so that i can make use of it for displaying it to the user.

I think you can use max id of Table.

Thanks for the answer.............but
i have a scenario where Lets say presently last column id value is 30, but there were 4 records after Column id = 30. but now they are deleted from the table. so i need to the column id value = 34 when i execute the query for the Current Identity value but not the value = 30.when i use max(id) i get 30 which is not what i am looking for.

The value returned from ExecuteCommand is the number of records modified by the command (in your case, you are not modifying records). See here. You probably want ExecuteQuery.
EDIT: I see you are using ExecuteQuery in your second example. I didn't notice that, as I was ignoring that line due to the syntax error you have there (extra paren).

See the documentation for ExecuteQuery. It will return a collection, not an individual number. You should also be specifying the return type. Get the first item from the collection and you should be good to go.

You could also try "SELECT @@IDENTITY"
But what you've got is already correct (for SQL 2005, at least), so it may be a LINQ problem, not a database problem (and certainly nothing to do with asp.net).
You might have better luck in the LINQ forum.
EDIT: Ah. You already moved there.

Hi
I have a situation where i need to upload many files at a time. The number of files can be any thing like 1, 100, 144, 1000, or 500 or any number. a user will come he will select a folder the uploader should loop the folder and upload every file that is present in the folder. Does there lie a solution to this problem in asp.net.

I don't think this is possible directly with asp.net. Security issue in web.
However, you can achieve this using Flash, silverlight or ActiveX in your web application.
I would suggest, search solution(s) in those area.

|
|
|
what security issues are there?
|
|
|
|
|
I would not allow any browser to read my hard drive(s)/Folder and send the file information to the server.
It is ok for me to upload the selected file based on need AND with my permission. But if anything is getting uploaded, i should be properly aware of them.
Please note and every user is not a developer and they may or may not be aware of what your site is doing.
I hope this answers your question. If not, you may google it. A lot of thread has already discussed on "File Upload security issue".

Check out this JQuery Plugin ('Uploadify'): http://www.uploadify.com/demos/[^]
It still needs to you to select all files in the folder and may not be able to recursively select folders in it.

Good day
I am using Visual Web Developer 2010 Express to develop a website.
I am using a FormView to edit and display records. I am trying to format the layout of the FormView so that I can arrange my data in the FormView in columns.
Something like:
Hosp Number: 100000000
Last name: Mouse First name: Mickey
DOB: 01/01/1923 Admission: 06/06/2011
I can do it quite easily using Tables, but I see that most people suggest moving away from using tables to do layout and rather use css based tableless design.
I am a bit stuck now. Have done some searching, but even Microsoft’s examples of FormViews use tables.
Does anyone have an example for me or a URL where I can go and look?
Thank you for the help.

Hi,
How to open pdf file in the new tab or new browser in asp.net. Right now I can open the pdf file in another window but I want to open it in browser or in new tab.
The code that works to open pdf in new window is shown but I want it in new browser..
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=a.pdf");
HttpContext.Current.Response.Charset = "";
HttpContext.Current.Response.ContentType = "application/pdf";
StringWriter stringwrite = new StringWriter();
HtmlTextWriter htmlwrite = new HtmlTextWriter(stringwrite);
repeater1.RenderControl(htmlwrite);
StringReader sr = new StringReader(stringwrite.ToString());
Document pdfDoc = new Document(PageSize.A4, 50f, 50f, 40f, 40f);
PdfWriter writer = PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.NewPage();
pdfDoc.Close();
any ideas?

As per my understanding, your page is may be open on any link so set link attribute target=_blank.
OR please explain, how you are opening page?
