Something must be wrong, as this is probably the most basic validation example ever - yet I still can't get it to work properly, and I actually suspect an error somewhere.
Create an aspx page with a textbox, a requiredfieldvalidator and a button. Set the validator to validate the textbox and set its text property to "*". Run the project. Now, I would assume that clicking the textbox and then tabbing to the button would show me the text-message from the validator (the red *), indicating that I haven't entered data where I need. Guess what - it doesn't show up...
However, clicking the field, entering data, tabbing away and then back, deleting the data again and then tabbing away again DOES show the red *. Because the validation of the textbox is handled from the onchange event. Try running this in the url field:
javascript:void(alert(document.all.TextBox1.onchange))
- it will give you
Message from webpage
---------------------------
function anonymous() {
ValidatorOnChange(event);
}
, whereas the
javascript:void(alert(document.all.TextBox1.onchange))
will return null.
Manually hooking the onblur event to the onchange event as so:
javascript:void(document.all.TextBox1.onblur=document.all.TextBox1.onchange)
will introduce somehow correct behaviour.
Now - is it me who has failed to understand the simples of all validation scenarios - or is the requiredfieldvalidator broken. I hope it is the first option, but what the h... am I missing?
Sample code:
<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
ErrorMessage="RequiredFieldValidator"
ControlToValidate="TextBox1"
Text="*"></asp:RequiredFieldValidator>
<asp:Button ID="Button1" runat="server" Text="Button"/>
</div>
</form>

RequiredFieldValidator is a server control and is not evaluated until a postback occurs. The onblur event is handled on the client.

Greetings. I am developing an e-attendance application in asp.net and c# code behind. I want that staffs will take their attendance through fingerprint scanner when entering into their offices. Only managers and HR staffs will access the e-attendance for reporting purposes. Please advise me on how to proceed.

Outsource it. 
What have you done so far?
You need to come up with a design, and later if you find any problem than you can come up and discuss here.

Yes... There are few fingerprint scanners there (even I have one which I use when login to the windows) which gives us the support to get the actual fingerprint id from that or otherwise you need to train first about your fingerprint and it will check with it each time.
But in all the situation the user needs to install driver to the client himself and also attach the small fingerprint device to it. In case of web, everything that you get is the web interface. So if you implement your website using fingerprint scanner, each client should have the fingerprint detection software installed, and also you need to somehow interface their data to your web browser. I guess you might need browser plugin also to implement this.
Everything depends on the device you are using.

hi,
this is kesava
i created a windows usercontrol and make it as strong name and also registered using regasm after make site is trusted and i used in web application it works fine .
But the problem is if i want to run this application on the other system it wont display the usercontrol .
If anybody know the solution please send a mail to me(ramki.pindi@gmail.com)

What ??
You are telling me that you have placed a windows usercontrol in a web form?? 
I think what you did, is you called the process exe of that windows application which is installed in the server. In case of client, as they doesnt have that installed, it wont run.
I think you need to clear up your basics on how web env runs before you actually proceed writing code. In web browser can only run html code. It cant understand anything other than this. If you want your client to run your application, you need to make them download the file and then install it to them and run that themselves.

I created the windows application as usercontrol and place the dll in the root folder of the web application .After that using <object> tag i placed the usercontrol on the web page it works on my system but when i try to run this application it will show only the rectangle border on the other system.
|
|
|
|
|
This will require every client using page with user control must have .NET installed.

in that system also having the .net

Hi all,
I have a set of help files(html files) in the application root directory. Now these HTML files can be accessed by the users even if they are not logged into the application. How can I restrict this?
Similarly, how can I restrict users to download java script files which is in my application root directory by directly typing the URL in the browser.
Please note, the authentication mode is windows and framework used is 1.1.
Kindly help...
Thanks in advance..

Well.. .Actually browser makes separate http request for each individual external files.
Rijz wrote: Now these HTML files can be accessed by the users even if they are not logged into the application. How can I restrict this?
To make access to the html files.. I would suggest to use separate HttpHandler which will authenticate your request againist some session id, if session is created already or will do it using uid and password.
Rijz wrote: Similarly, how can I restrict users to download java script files which is in my application root directory by directly typing the URL in the browser.
In case of Javascript as a separate request is made from the browser, it would not be a good idea to restrict the download of the file. Some browser requests javascript after document is fully loaded, but there are others which actually starts download of the file as soon as it parses the Javascript tag. So you cant trap the behaviour of the browser.
Rather, I would suggest you to edit your javascript and place your sessionid within the url. Place your sessionid in a sesssion variable or in database. Create a separate HttpHandler for Js file which will check if the sessionid(might be your custom GUID which you generate during the login) passed with the querystring is valid for the current user. Allow download of the javascript only when url is valid.
say in your browser you place script tag like this
<script type="text/javascript" src="yourjavascript.js?sessionId=<%=this.Session.SessionId%>
Now from ProcessRequest of IHttpHandler, check
string qry = context.Request.QueryString["sessionId"] as string;
if(!context.Session.SessionId.equals(qry))
{
context.Response.clear();
context.Response.close();
}
Also remember to implement your class from RequiresSessionState, otherwise session will not be available in the
HttpHandler .
Hope you got the idea. ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

 Seriously though, you have a point about text messaging, using a cellphone keypad - but I assume you're using a proper keyboard for posting here, and so there is no excuse for using text speak.

Hi,
I am creating item template dynamically inside gridview in Asp.net 2.0.
The Item templates are sucessfully created.like as follows,
Assume below as a grid view Rows & Columns :
EmpID EmpName Basic HRA MA TA PF OTHER
-------------------------------------------------------------
1 Employe1 10000 1000 500 400 300 700
2 Employe2 20000 2000 800 600 400 800
3 Employe3 30000 2500 900 700 400 900
-------------------------------------------------------------
so the above coloumns as item template created dynamically First 2 column are labels and rest of the columns are textbox...So the first time loading the gridview with 3 rows empty - then i will enter data then i will save it to database... so UPTO here working fine...
Note:
The problem is i can change the text vaue from any rows any coloumn, i want find which rows and which cell was changed ,, how to find this..plz tell me ...
i ll give code snippet,
Gridview_RowCreatedEvent()
If e.Row.RowType = DataControlRowType.DataRow The
Dim txt As New TextBox
For inti = 0 To 7
strname = "txt" & inti
txt = CType(e.Row.FindControl(strname), TextBox)
AddHandler txt.TextChanged, AddressOf txt_TextChanged
Next
End If
Regards,
Sekannak....

You can set the id of the control to contain a row index, then in your text changed event, check the id of the control that fired it. You can also use it's Tag property.
