Web Forms :: Server Error Message + Client Side Validation Message?
Apr 19, 2010
I have forgotte password page in my application,page have one textbox to insert email address,when user click on submit button if inserted email address (i.e. firstname.lastname@example.org) does not exits in DB it will give custome error message like "Email ID not available".after that suppose user will enter inproper email address (aaa#gmail.com) than client side validation for regular expression will file "Email id not valid",at same both message be on screen,now i want only one message at a time.so please can you help me for same
I am building a CustomValidator, here is my html declaration:
I have this admin page where i want to throw an error if they select more than 5 items from the list. I was trying to do this on the server side. When the selected items is more than 5, I get an error screen.
i am working in a web form (VB.NET ) in which for certain transaction i need the user OK to continue or not.
all what i found is about adding onClick event handler for buttons, but in my case there is no button to click , it's a process in which i retrieved data from database and if that data met specific conditions then a message of OK Cancel should appear to the user prompting him if he would like to continue in that transaction .
I am coding with VB.Net 2005. I have an issue popping up a message box on the client's side. The message box works well when running the application on my local machine, but when the site is hosted on the server, there is an error showing a conventional message box()in vb.net 2005 on the client's machine.
How the ilusion of causing site to change content from server side is done? Let the example be gmail chat or chat on facebook. Or even new message sign on stack overflow.Is it done by http://en.wikipedia.org/wiki/Comet_(programming) ?
I'm interested in identifying a means to verify the server-side validation is performing as expected, but need to bypass the client-side validation being done using ASP.NET validation controls. To test this, I've tried using the form Poster add-on to Firefox that allowed me to get/modify the page contents and post it, but the .NET framework interpreted the submission as harmful and threw an application error ("A potentially dangerous Request.Form value was detected from the client").I've created a WinForm that includes a WebBrowser control and I'm able to manipulate the contents of the web page and invoke the button click, but am interested in seeing how to allow a postback with invalid input values. I don't want to assume the server-side validation works (even though I do check if Page.IsValid on the server on postback).This submits the web form in the WebBrowseer control and the expected client-side validation fires: extendedWebBrowser1.Document.GetElementById(formButtonName).InvokeMember("click"); This is how I've manipulated some of the page contents (this just prevents submission): mshtml.IHTMLDocument2 doc = extendedWebBrowser1.Document.DomDocument as mshtml.IHTMLDocument2; string html = doc.body.innerHTML; html.Replace("Page_ValidationActive = false", "Page_ValidationActive = true"); doc.body.innerHTML = html.ToString(); extendedWebBrowser1.Document.GetElementById(formButtonName).InvokeMember("click");
control is checking that a textbox.text value is a string. If I input a number the error message appears as expected, but does not dissapear when I enter text backover the numbersDoes anyone know how I can solve this problem as I cannot submit the form?
On a check box check changed I want to test some conditions and based on that I want to display a confirmation message. Based on the user action, OK or Cancel I want to proceed or stop the process. How can I do that. I tried this,
Even I click Cancel the rest of the code also executed. How can I handle this?
I am uploading pdf file... if I click upload.. I will check the pdf file .. PDF file page size .... should show message size checked or else invalid size if it successful size then it will check landscape or portrait.. and so on operation... but while checking the pdf file i want to show message to client this operation is going like.. progress bar..
i am using create user wizard and capturing other information within content template when a new userregisters. Some of the textboxes are binded to required field validators.there is a validation control on the page and ShowMessage box is True.If they dont complete some of the text boxes then the message box pops Up with the error message.It does not however include information errors like "User already exists" or Email address already existsfrom the create user wizard membership UserName and Password Textboxesis it possilbe to hook all of these up so I get one message box with all errors including membership ones?
By default in login template, in case user key in the wrong user name or password, the literal message will show the default error message, "Your login attempt unsuccessful..."What i trying to do is, I have a function in my system to disapprove a member, after the member is disapproved, he/she will not allow to login anymore. When the user trying to login, the default literal msg will show out. Is there any way i can do it more specifically like if the user enter the wrong password only, the literal msg show: "Wrong password entered" insteaed of the default msg?
Same goes to the change password control, for any error msg it just show the long msg but does not tell user whats wrong with the entered valueim trying to do something like if the user enter the wrong password, the literal msg show the one i wan to show.
