The error message that gets added to the validation summary when the form is invalid I need to get access to in client-side JavaScript. How do you access the actual message? My page doesn't have a ValidationSummary present, and Page_Validators[0].errormessage is *. Where is the message?

I have an asp.net application with basic CRUD functionality. On a page where i am capturing customer details i have several asp.net validators to required fields. I have attached a JS confirm box on the asp.net save button for the form. The trouble is that when the user leaves required fields unfilled and clicks the save button, the JS confirm box comes up, when the ok button is clicked, the save method is called successfully and only after this happened do the asp.net validators fire and display that required information has been left out.

View 2 RepliesI have a custom validator, i want to change the Error message dinamically.
[Code]....
How can i use the 'val' parameter. Could tell me how the Error Message can be changed dynamically ?
If I have something like the following:
<asp:TextBox id="test" runat="sever"></asp:TextBox>
<asp:RequiredFieldValidator runat="server" ControlToValidate="test"
ErrorMessage="Required"></asp:RequiredFieldValidator>
<asp:Label runat="server" id="lblStatus"></asp:Label>
if in the code behind, I set the label to "You must enter a value if the textbox is empty" to validate it on the server side and this is fine, but if javascript is enabled, I don't want to show the client side validation and the server side label together. Is this something where I would just have to disable the client-side validators if javascript was enabled?
For the ASP.NET validator controls, I want to use both client-side validation for the user experience and server-side validation to guard against hackers. ASP.NET documentation leads me to believe that if EnableClientScript="True" then there will be no server-side validation if client-side validation is possible for the user agent. To get server-side validation, the documentation says use EnableClientScript="False", which bypasses client-side validation altogether.
Am I misunderstanding how the validator controls work? I ask because it seems obvious that many developers would want both client and server side validation together, and I find it hard to believe both together is not possible with one of the standard validation controls.
If I am understanding the ASP.NET documentation correctly, then I can find only two options:
Use two validator controls exactly the same except for their ID and EnableClientScript properties. Obviously ugly for maintaining two controls almost the same.Write some code behind to check if postback then invoke the Validate method on the validator group. Why write code behind if there a way to be automatic from the control?
Is there a way to do so using a single validator control with no code behind?

View 1 RepliesGiven an ASPX page with a textbox, a requiredfieldvalidator, and 2 buttons.If I want to only have the requiredfieldvalidator validate that data is in the textbox if button1 is clicked but not button2, is my only option to set EnableClientScript to false and do validation on the postback?Or have they implemented a way where you can still do the client side validation, but specify for it to only occur if button1 is clicked and not button2?

First of all, awesome job in the MVC 3 RC. The Razor view Intellisense, validation improvements, and many other things are most excellent.A question to those who have struggled with complex validations like me (it led me to pursuing Ajax-based validation using a 'roundtrip validation' concept...http://mvcajaxvalidation.codeplex.com/)... I couldn't wait to have a pure client-side jQuery method that was well integrated with data annotations so I could drop the work-around attempts.So, I was excited to see how easily and well Remote Validation works. In fact, the way I could pass other fields along with my validation request was unexpectedly awesome. However, I was very surprised when I turned off JS and noticed that the data annotations which allow the Remote Validation check do not work server-side like all other data annotations that I've tried. Are there any plans to include this? I don't mind doing a custom validator just for the server-side, however, it will be a somewhat redundant annotation unless I'm missing something?
View 3 RepliesI have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)
<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...
There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)
<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...
There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.
<script type="text/javascript">
//<![CDATA[
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");

Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.
I was curious if one can use RequiredFieldValidator and other validation controls for client-side validation on a production site?I looked in the docs but could not find any mention of validators.
View 3 RepliesI have a text box in which I want only digits (either decimal or whole numbers). I have applied Required Field Validator and Regular Expression Validator on it.I have an Image Button, by clicking on which, I want this validation to be performed. But when I build the code, and clicks on Image Button, these validators do not work and I am redirected to the server side method of Image Button and after completing the execution of server side method, control comes to these validators and client side validation executes.I am fed up by finding solutions on Google and unable to find any solution.Please tell me of anyone of you know the solution that why server side code is running first and client side validation is executing after server side code execution.
View 11 Replieshere is the problem I have:There are 2 textboxes: uxActiveDate, uxExpireDate. Expiredate has 2 validators attached to it:
In the markup:
[Code]....
In the code behind file:
[Code]....
The problem is when expire date is selected before active date, and current date, then both the error messages are displayed. I have to set priority or something so that these 2 messages are not displayed at the same time. Is it doable?
PS: Since if required field validator does not pass, then other validators dont execute, I guess there is a way to set priority so that if one validation is not passed others will not execute. Validation summery is not an option, since it does not show message client side.
I have a requirement of adding server side variables in client side and other way round. Because I need to set a value from client side using javascript and access the same in code behind page.
I have to use C#.Net and JavaScript.
I have a list of items on an ASP.net page. That list is selectable in that whenever the user clicks on one, the page does a postback and the server code stores the index or some unique identifier of the picture in a ViewState property indicating that it is currently selected.
I would like to minimize the load on the server and therefore I would like to store the index or unique identifier representing the image in some way on the client side. The best way I can think to do this is to store said information in a hidden field ), however I had two questions about this before I go crazy:
Is this a security risk in any way, shape or form (i.e., exposing implementation details of the page)?
Is there a better/best way to do this that is more industry-standard? Does ASP.net provide a framework to do this that is cleaner than my idea? Seems like this would be a fairly common requirement to me...
