I have two buttons on my page, the first page is View Button and the second is Update Button. View button display's member's personal profile. If I click on the view button, my custom validator automatically trigger, meaning, it automatically displays the error message. Whereas, the custom validator must trigger if I click on the Update button. How am be able to deal with this kind of problem.
View 6 RepliesI have a custom validator and some other validators on the page. But whenever I click the submit button for first time it only fires the custom validator and when I click the button for second time it's validating rest of the validators.
View 1 RepliesI have a project I'm working on, which is basically filling in a form online. The form contains multiple pages, and I have replicated this using a MultiView. On one of the pages I have a CustomValidator which validates a driving licence, based on names/previousnames and the date of birth.If the validation fails, I want to enter a link into the text, which will allow the user to click on it and correct the information that is erroneous.
View 3 RepliesI've got two questions - first of all, why does .net render a javascript onclick event for asp buttons when there's a custom validator on the same page, and secondly, how can I get rid of the javascript?
It works fine when javascript is turned off, so I don't know what the point of it is. Here's a mini example:
<form id="form1" runat="server">
<asp:Button ID="Button1" OnClick="Button1_Click" Text="test" runat="server" />
<asp:CustomValidator ID="CustomValidator1" runat="server"
OnServerValidate="Stuff_Validate" EnableClientScript="false">
</asp:CustomValidator>
</form>
This will generate the following html for the button:
<input type="submit" name="Button1" value="test" onclick="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("Button1", "", true, "", "", false, false))" id="Button1" />
Without the custom validator, it's:
<input type="submit" name="Button1" value="test" id="Button1" />
I created my custom validator in one project, something like that:

he composite control in another project. I added a reference of the custom validator project to the composite control project. I have a textbox in a composite control and I would like to validate this textbox by the composite control I created. But how can I do that? How can I create the custom validator instance that is linked to the custom validator I created?
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

View 1 RepliesI have a validator callout extender that works, it shows the callout box. But, it does a postback. It didn't do a post back the first time I clicked the button but it did for subsequent times. I read on the AJAX site that a custom validator must be used with this for it to work. I'm currently using this with a required field and regular expression validator. It works, the callout appears, but it doesn't work every time with out the post back.I posted this to see if there is a way to get this to work with a required field and regular expression validator, with out using a custom validator. I'm using the newest release of the toolkit, so I thought the documentation may be old, since the callout is appearing.
View 8 RepliesI've been trying to get a custom validator component working that ensures at least one checkbox from a checkboxlist has been checked. I've been used some code I found on dotnetjunkies.com but the client-side validation didn't work. I've been attempting to modify it to get the client-side javascript validation to work with no luck. Basically, I compile the below code into a DLL and add it to my bin folder.

View 4 RepliesDoes anybody know of a way to set the width of a custom validtor so that the error message text will wrap if it exceeds the specified width? I have a user control that contains a custom validator which the containing page can set the error message on based on specific validation results. he user control sits within a table cell in a page. If the message is very long it simply prints the entire message on a single line ignoring any column widths that are set. I have tried setting the width property on the custom validator itself to no avail.
View 2 RepliesI am trying to understand a little more about implementing a custom model validator. I have implemented a custom model validator (derived from DataAnnotationsModelValidator<T>) for my custom validation attribute in order to do validation on the client side as well. There is not much documented about DataAnnotationsModelValidator. Besides, implementing client-side validation when is it a good idea or needed to implement a custom model validator for a custom attribute?
A separate question - in trying to understand how and when a custom model validator is used by the framework I noticed that my custom validator is always created with the context (2nd parameter in DataAnnotationsModelValidator<T>'s constructor) being a ViewContext, although it is declared as ControllerContext. Will a validator ever be created with something else than a ViewContext, and if so, when?
My CompositeControl creates dinamically several RadioButtonLists according to the DataSource information. These controls are added to the Controls list and rendered in CreateChildControls event.
I need to create a LinkButton that clear a specific RadioButtonList selection and do a postback, to load the DataSource information again (some selections changes the data that need to be loaded from the database). For each RadioButtonList, I've put a LinkButton and assigned the Click Event to a method inside the same CompositeControl, to do the RadioButtonList cleaning.
Unfortunatelly, the LinkButton doesn't trigger the Click Event. In HTML code, the link has the "onclick" attribute setted with the asp.net event, but when clicked, nothing happens.

I have a custom validator, which I have set a property for, and I can access this validator from my MVC controller method. However, when I run the code, I am not seeing the error message on the page. My code in the controller method looks like this:
If (!bool)
{
this.view.customValidator.IsValid = false;
this.view.customValidator.Visible = true;
}
I am using Customvalidator control . I am giving client side validation function in it. On running it is giving error as: ValidationStream is not defined.
Following is the code:
<asp:CustomValidator ID="CustomValidator6" runat="server" ClientValidationFunction="validateDriveDate"
I have two custom validators that are in the same validation group. This validation group is launched by one button. My question is, in what order will the custom validators fire in? It appears that the validator that is placed earlier in the aspx page fires first, but I don't want to rely solely on this.

I have quite a few text area's on my page and am wanting to limit the number of characters for each one. However each one should be able to have its own maxlength (i.e. one could be 20 characters and the other could be 100 characters). My validation on the page is all done using custom validation as the built in validation of .NET is not extensible enough for me to display my validation errors how I want to display them. So this is what im wanting to do:
Make a custom validatorPass a MaxLength value from the custom validator into the javascript function, this value must also be accessible from the code behindI can then run client side and server side validation on each textbox control. The problem I am having is passing a MaxLength value to client side script and to server side. Is there a property on custom validators which I can use to pass values around? For instance in Javascript I would want the value of the MaxLength and also the id of the Div which will show the characters remaining, and server side I would need to know the MaxLength. I have done lots of research on this and cannot seem to find an answer.
I have a form with textbox for name and two dropdownlist for month and years. Textbox has Requiredfieldvalidator and the dropdowns has got ustomvalidator.Initially when i dont enter anything in the text box and leave the dropdowns with default "MM" for month and "YYYY" for year i get error message in the validation summary at top and asterisk next to the textbox and dropdowns. Once i enter some text in the textbox and focus is away from textbox the asterisk disappears but even though i hav selected a valid month and year the asterisk next to the dropdowns is not disappearing. Same problem with the radio buttons.

I am working on a custom form field validator, it seems like the custom validator is working by not allowing it to continue to the next page, but it doesn't update the Validation Summary nor does it display the asterisk and the labels that i've made visable. I also have other validators like RequiredFieldValidator on the same field. My ValidationGroup is set, as is the Text and IsValid. I even wrote and set a dummy client side validation method in javascript as some workarounds suggests.
here is the validation summary code in asp.net
