Web Forms :: Error Message For Validator Controls?
Jul 28, 2010
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 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'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 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 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 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 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>

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 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 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 compare validators that I build on the fly in code behind that validate textboxes that are also built up in the code behind:

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 working on web-form for which I have set the validation summary showmessagebox = "true".
I have two required field validators, which trigger on a checkbox's OnCheckedChanged event....now my problem is, when I hit submit, the page does not submit if I do not enter any values in the text boxes..which is correct behavior but it does not point out to the error or does not display the message box.
i have to scroll up to see what is wrong with he page and then try to enter the values...I do not understand why my message box does not show up or at least why my setfocusonerror which is set to true does
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. abc@gmail.com) 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 have a textbox with a required field validator and two buttons .One to save and other to cancel the action. On clicking the cancel button i am clearing the text entered in textbox.
The required filed validators is working on the save button if the textbox is empty. But on my cancel button click the required field validators message is blinking .
I have a validator on a textbox that validates against a list to ensure that the user doesn't input the same name. When testing it, if I type in the same name including the same case structure, it returns an error. If I change one letter to a different case, it doesn't return an error but rather my SQL server returns a duplicate error. How do I change the server-side validator so that it picks up duplicate names regardless of case?
When I add an update command to my page and run the page I get this error message
Server Error in '/MYApplication.

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.
I have 5 fields on my web form out of which 2 are hidden. i have to validate all of them so i have associated required field validator with all of them. it works fine it does not shows me the error message for the controls that are hidden at that point of time.now i added a custom validation control and when this validation fails all the error messages are shown... can some body please tell me what am i doing wrong and what is the best approach that can be followed in this case.

I have a gridview control contained in a web server panel control. When I move the panel (drag by means of the direction icon in the panel's upper left) the gridview control disappears and an error message appears in it's place. And it states "There was an error rendering the control. Object reference not set to an instance of a object". This must be coming from the code that creates the web page.If this might have a bearing on things the panel conrol is absolutely positioned and the gridview is relatively positioned.
