OK, this is far too hard for you. You should buy a book and work through some basics before you throw around terms like AJAX ( useless for what you want ), because you read about them on the toilet. Learn the basics, and understand what a technology does before deciding you want to use it for something that is completely unrelated to it.

Hi,

I have created a webpage that connect to a DataSet. The layout of the app is as follows:

Page.aspx

DAL Folder
dsTSQ.xsd

DataConnector
IConnect.cs
Connect.cs

When I put the code to save a record in the save_click event the code looks like this:

this.validate();
dataConnector.UpdateJob(this.dsTSQ);

The problem is that when I try to input the dsTSQ dataset the app says that I might be missing an assembly reference. I have checked and the access modifier for dsTSQ is public.

I have made a new instanciation of the dataset but when I save nothing gets written to the database. Does anyone have any thouhts?

Thanks!

Illegal Operation

Hi,
I want to create a page with Ajax support that has a table showing 20 products the use may buy. The user must fill the quantities (for the desired products) and leave some (or all) blank then click the submit button. When he clicks submit I'll execute some code that update the db order table and fill the html with the next 20 products (if any), that's why I'm gonna use ajax.
My questions are:
1) What controls should I use to repeat the table lines 20 times (or less if there is not 20 items left)
2) How do I trace what products have quantities not empty?
Thanks,
Dirso.

PS: Sorry for this n00b question

Thanks,

look at GridView[^], here are some examples1[^], Example2[^]

Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area. Luc Pattyn[^]

i can do this on jsp but how this could be done in asp.net
thanks in advance

hi!! i am using a 3rd party dll in my project to html messaging like this message board in codeproject or a scrap like thing in orkut.
but every time when i pressed the send button of message it gives me error and message is not stored in db.
the error type is:

Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. You can disable request validation by setting validateRequest=false in the Page directive or in the  configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case. 

A potentially dangerous Request.Form value was detected from the client (ctl00$ContentPlaceHolder2$TextBox22="dfg<br>").

Try reading the message genius.

Sorry. I was still mad at you for earlier. I didn't mean to make fun. You can disable the validation but it is a security risk. The built in request validation blocks people from using scripts to hack your server.

I didn't get any requirements for the signature

yes ! i assume that it could be risky but how then they(other sites like cp or facebook , orkut, etc.) manage that risk.

I can't help you with that one. I've never turned off the validation on an internet site. I've only turned it off on a intranet site which has less risk.

Anyways! thanks.

If you turn off validation it's up to you in your codebehind to validate all input before using it. Google "SQL injections" if you are writing to a database for example.

Request validation is used for defending against various attacks such as XSS(Cross site scripting), Sql Injection etc....

Turning of this validation can make your page prone to such attacks. For this purpose microsoft has published an Anti XSS library that helps in validating the user input when such automatic validation is turned off.

You can download the XSS library here

and some brief explanation about using the library here

Hope it helps....

Dear Guys,
Please Help or reslove this prob.My pro is that -- my asp page is open which includes two radiobuttons,and when i selected both radio buttons,both are checked,so please give a suggestions hw will i resolve it so that only one radiobutton can be checked at atime...

Reply Soon.

Use a Radio Button List (only one option may be checked at a time).

Or write some javascript to uncheck one when the other is checked.

oh! boy!!! dont you have any basic ideas of asp.net
well you have to group those radio buttons by properties window(may be you know that thing) if you are using VS and also you can use the radio button list

cheers!!

No, I don't know a damn thing about asp.net. I've only been working full time doing ASP.Net development for about 8 years now. I have only successfully implemented about 100 corporate applications. As a matter of fact, most of my posts are just nonsense. I don't think I've helped a single person on this board ever.

Thanks for your comments.
