Web Forms :: Validator Error Messages Hides On PostBack
May 7, 2015
Required field validator error message is disappeared, after post back event. how to maintain the Required field validator error message on post back also?
I'm having a registration form with textboxes that have more than one validator, e.g. a requiredfieldvalidator and a comparevalidator. I want the error message to show up on the right side of the textbox, but because I use more than one error message, one of them is not neatly next to the textbox, but further away from it.
This control is used multiple times on one aspx page. The issue is that each time an instance of the control is validated due to a text change any prior error messages are cleared from the validation summary. I want the validation summary to maintain prior error messages during the postback.
For error messages, validation faults etc you have
ModelState.AddErrorMessage("Fool!");
But, where do you put success responses like "You successfully transfered alot of money to your ex." + "Your balance is now zero". I still want to set it at the controller level and preferably in key-value way, the same way as errormessages but without invalidating the modelstate.
I work with ModalPopupExtender (ajax control toolkit) asp.net
that is to say that a popup appears which contain one panel with 2 DropDownList (DropDownList1, DropDownList2)price starting from DropDownList1 the DropDownList filled due to the code behind.
My problem is that when I click on the DropDownList1 ModalPopupExtender that contain the Panel is gone because of AutoPostBack = "True" of DropDownList1.
When I browse to my page that has the modal popup panel on it, the panel initially is visable, and when I do a postback it acts as intended. let me know if you need the master page....
The objects I was passing to the ValidatorHookupControl were'nt being set properly (were null). Now that they are, the messages are currectly dissapearing when the hooked up control looses it's focus.
I have some ClientValidation controls that have ClientSideValidation methods which work fine when validating the page..
However, how can I make it so that when a certain control that a CustomValidators clientside method kicks in and udates the validation message depending on whether the validation has passed or not. (Like the RequiredFieldValidator or RegExValidator).
My Customvalidators do not have their ControltoValidate properties set as some of them depend on multiple controls.
I don't want any postbacks (full or partial).
I have tried..
1) Adding an onchange attribute on dropdowns, radioboxes and checkboxes that call a helper clientside method which calls Page_ClientValidate('GroupName'), then setting window.location back to the control in question (as it went back to top of screen).
Using this method the args.IsValid is still being set by the ClientSideValidation method.
2) And I have tried ValidatorHookupControl (control, validator) but that doesn't seem to work either.
I have a validator with a ValidatorCalloutExtender. The validated TextBox is set to empty string after postback and this unfortunately causes the callout to popup. There must be a way to restore the validator to its initial state but I cannot figure out after trying quite a few things including setting IsValid to true.
I have a form that has contact fields, billing address, and shipping address. So if i fill out my contact information ONLY and left billing and shipping address blank then hit submit, the validation for the billing address and shipping address appears. Ok no problem, there is a check in each billing and shipping fields that once click on it copies the address from contact to billing or shipping fields. Everything works except for the validation messages. They are still there. Is there a way to remove the validation message after the textboxes are populated with data?
In my page, I have to display confirm message box with some condition. It should not display always. I have written below code, but its giving errror.
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "confirm", "return confirm('Are you sure');", true);
I can't do like below code, because I am getting some value at runtime and i need to check. btnLogout.Attributes.Add("onclick","return confirm('Do you really want to log out?
In my app i have a master page that all content pages use. I would like to have a centralized area inside my master page that would handle displaying of error messages. So on my master page I would have the following this is where the content goes So when I would submit a content page, placeholder named "ErrorPlaceHolder" would be found and error would be displayed in the pages "Pre Render" event..I guess. How would I do that?
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 have the this current design. I use a web service/jquery perform client-side validation and to return 1 of 4 integers. At present I store it in a hidden field but it could be passed directly. I then deploy4 validators that when validated, validate the integer and trigger a custom error message. The ideal scenario I would like to be able to do this with one validator and switch the error message accordingly. On the server side the code could look like this:
[Code]....
As you can see my error messages are held as strings elsewhere which I reference for continuity throughout the project. unformtunately I don't know how to achieve this client-side by calling a javascript function. Sure I could hard code the messages in the javascript file as well, but this would mean that they were held in two places and suseptable to error. It may be an option to return an error message in the web service rather than an integer and trigger if it is blank.
I have a validation summary (vs) and required field validator (rfv) on my page. The validation groups are not set in either of the controls. When I leave javascript on, the rfv fires correctly and the error message appears in the vs, as well as a * appearing next to the textbox I am validating. When I set the EnableClientScript=False for the rfv (forcing a postback and server side validate), the * appears, but the error message doe not appear in the vs. Why is the error not appearing in the vs? The fact that the * is appearing shows that the validator is being fired.
I want to do: when I was clicked the btnSubmit if All texts are empty popup will show !!!
My code is here ;
<html lang="en"> <head> <meta charset="utf-8"> <title>jQuery UI Drop Effect</title> <link rel="stylesheet" href="css/drop.css"> <script type="text/javascript"> function ValidateDropDown() { var value = document.getElementById('<%=TextBox1.ClientID%>').value; var value2 = document.getElementById('<%=TextBox2.ClientID%>').value; var ddlVal = document.getElementById("DropDownList1").selectedIndex;
When I Login the page using username and password and then click the logout button and after again click Login button without entering username and password it will be login,I want to show error
asp.net with vb. I thought this would be easy but have been reading for an hour and not found out how to simply repost a page where form data has been entered and return the page with some error messages about what was entered. I want to return the page with all input controls with the data just as the user entered them before submitting. the error messages are labels that were blank when the page is first loaded. preferably the page returns focused to the topmost error error message. if that can't be done I would populate some label at the top of the page with something to the effect that 'errors were found, scroll down to see the errors'
Here second declaration of x gives error that "variable 'x' hides a variable in an enclosing block. I wonder why this error is not given for second 'i' variable declared in second for loop?
Since i am declaring second x in a separate for block, why this error is given for variable second x ?
This is probably going to end up as a stupid question, but countless research has offered me no results. I know there are different types of errors I want to check for, and when I should be throwing an exception for "exceptional" errors, and that I should create validating functions for input and other checks. My problem is, how do I send an error back to a page when the data entered fails in a separate class?
For Example:
User input entered in Page1.aspx, click calls Submit() in Class.vb Class.vb finds that input is invalid How do I update Page1.aspx label to say "Hey, that is not right".
