Why The Error Message For Custom Validator Is Not Shown In Message Box
Jan 16, 2011
I have tried in many way but the error message for custom validator is not shown in validation summary but it(ValidationSummary) shows error message for every other type of validator.
I have a requirement that one of multiple fields is required. Using custom validator the even fires, false is returned, but no error message is display and the form validates. What am I missing? I have tried with and without ValidationSummary.
<asp:CustomValidator ID="QuestionValidator" runat="server" ErrorMessage="Please select an option" ClientValidationFunction="QuestionValidator_ServerValidate" OnServerValidate="QuestionValidator_ServerValidate" ValidateEmptyText="true"></asp:CustomValidator>
[code]...
When I run the page, there is no validation and no error message. Please can you point out where I am going wrong, I'm suspicious it is at Page.Master.FindControl("form1").Controls.I have previously done such validation by looping through controls via form1.controls but this is unavailable as the page uses a form passed down via the master page.
i ahve one custvalidator control in that i have used OnServerValidate="ValidateDateRange" ValidateDateRange is function i have written in serverside now i want raise error message without postback operation like (clientside validation) if that ValidateDateRange function returns false .
I have an aspx page with lots of controls on it. I am using a custom validator control (with the serverside validation). Is there a way to display the error message on the validation summary without writing Javasccript. I am a beginner in .NET and am not fluent in Javascript. This is the custom validator HTML
This is the utility method am trying to validate for the entry on the UI, so that it takes dates only in these described formats If the user enters date in any other format, this method returns returns the Datetime.Mivalue(1/1/0001)
public DateTime GetFomattedDate(string dateString) { try { string[] formats = { "MMddyyyy", // These are the accepted date formats for the UI "MM/dd/yyyy", "M/d/yyyy", "yyyy/MM/dd", "yyyy/M/d" }; DateTime EffDate = DateTime.MinValue; if ( DateTime.TryParseExact(dateString,formats, null, System.Globalization.DateTimeStyles.None, out EffDate)) { return EffDate; } } catch (Exception) { throw; } return DateTime.MinValue; } This is my customvalidator event handler(code behind) protected void ValidateDate_ServerValidate(object source,servervalidate eventargs args) { args.IsValid = GetFomattedDate(args.Value) ==DateTime.MinValue? false:true; }
I am able to validate it properly, but I cannot display the error message in the validation summary along with other messages. Anyone who is expert on Javascript can Help with the javascript function?
I am using a custom validator to call a javascript function for validation. My problem is that I need to be able to change the error message dynamically. Here is the code:
I have one doubt i.e i want to display the error message for the validator controls all the times regardless of whether one has entered a value or not. In my case i'm using few required field and custom validator controls.
By using Page.Validate() method i'm able to display the error message for all the controls , but this doesn't work in case the field has any value in it.
Please suggest if there is any workaround for this to display the error mesages for the fields with validator controls all the time.
I've got a booking form which allows users to pick dates. User clicks FromDate button which activates calendar control, they select date from calendar which then populates a textBox. I have a compare validator which checks that the SelectedDate is greater than the current date, if the SelectedDate is in the past then the validator fires error message. This works as fine, however, when the validator fires it disables the FromDate button so the user is unable to pick another date from the calendar as the focus goes to the TextBox which is being validated - how do I get around this? Here's the code:
I have a regular expression validation control initialized to validate a textbox control. I want users to be able to enter U.S. Currency values ($12,115.85 or 1500.22 etc.). I found a regular expression off of regexlib website that does the trick. The validation control seems to be working except for one crucial thing. If invalid data is entered, the validation text dispalys (a red "*" next to the textbox), but the page will still submit and the error message won't pop up... I thought that the error message is supposed to display and the page won't submit if the validation control detects invalid data. Isn't this automatic with ASP .NET? I have searched extensively on how to create validation controls, but haven't found anything different than what I am already doing. Can anyone tell me what I am doing wrong here?
I have textboxs that define requiredfield validator for them..I want when I click on button if users don't type text in textbox it shows popupmenu some thing like ModalPopupExtender that I can define div on it and it shows just this text" please fill required field".

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.

I am trying to handle the unhandled exceptions in my project.I tried with this following code in my web.config filebut it is not at all redirecting to an error page which i have created instead of that it is throwing an exception in my code itselef. How to print the error description over therein my custom error page.
I have an ASP.NET 3.5 Site where, in some places, I am checking if the currently logged on Active Directory user is in a certain AD Security Group. In the Page_Load I'm doing something like this:
if (isInADGroup(UserGUID)) { //proceed }
Now I was wondering, couldn't I just create a Custom Attribute, like some of MVC's security attributes, which runs this check and cancels the execution or displays an error message?
I am trying to passing Exception info tpa custom error page that I have created, and I'm looking for the best way to do so.I ended up creating a session object on my Global.asax page, and I pass the error data to the session object during the Application_Error event, but it throws it's own exception prior to working.
[Code]....
I have also updated my web.config with my error page that I would like to pass session object data to:
I have a grid within another grid. In the detail grid I have image button for which I am giving the URL of documents in the source itself. On clicking on Image button, document can be opened for which I am using a Handler. The code for opening the document is written in the handler.This code is as below:
[code]....
The document can be opened when clicked on Image Button. but, the problem is taht after opening the document, I am unable to perform any other action in the grids.... Other actions like...selection in checkboxes(master grid contains few check boxes),other link buttons in detail grid....etc etc...I am getting the following errr:
PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled
This is because after opening any document,for any action again Handler is being called.
I have compare validators that I build on the fly in code behind that validate textboxes that are also built up in the code behind:
[Code]....
These work fine until a postback occurs. After a postback they still validate the form (i.e. they don't let you postback) but the error message won't display.
I am using a compare validator control and also a ajax validatorcallout extender control for data check on a field.
Both of them work well...but only the ajax call out extender pop up error message should display ... right now I have both of them displaying.. it defeats the purpose of having calloutextender, if I am displaying the comparevalidatror message anyway on the webpage.
How do make it so that only the pop up calloutextender ajax is triggered and not the comparevalidator error message.
