I am using the Login control to create a new user. I have it where if the user adds and email address, then this automatically popuplates the username textbox with the email address. I want it where if they don't have an email address then the user can just create their own username instead.
But what happens is if they create a username, but the leave the email blank, a defined error message appears saying that an email must be provided. In the login control properties I have set the property
RequireEmail to False but the message is still appearing.
Can anyone help me find out why the email is always required? I do have custom validators for other parts of the login, but have no validation set anywhere for the email.

I'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.

I've got a custom control with asp:hyperlinks that's causing validation which I don't want... Is there anyway I can stop this from happening?
View 1 RepliesI'm hoping to discover how to add an email validation step to the CreateUserWizard. I've seen many sites where I create my membership, and then I receive an email at the address I gave, which holds an encoded link back to the website. It allows the website to confirm the email is working. I'd like to add this. I've found out how to use the maildefinitionbodyfile with user generated items, but can't find this function to require a reply by email. Could someone give an overview of what's involved (if it's complicated), or point out how to do it (if it is a built in function I'm not aware of). If there was a code sample somewhere, that would be the best possible outcome...

View 1 RepliesHow can we implement a custom validation of two controls as a unit, say a picture upload control and a dropdown ("0", ""100", "200") for the width of the picture display.
View 1 RepliesI am trying to set up my first custom validator in VS 2010 VB. I want it to use a Sub or Function that is in my code-behind. I have searched the WEB but the instructions and examples that I have found do not show me how to use code-behind.
The main problem that I am running into is that I can not find a way to connect the validator to a sub that preforms the validation check.
We have a page with quite a few textboxes and a dropdown list at the end. The dropdown list at the end is a "Result" and dependant on the result certain textboxes need to be filled in and this needs to be checked when they submit the page. I was thinking of using a custom validator
View 3 RepliesI have a custom control which I need to be able to operate with the validation controls available within asp.net. I would like the message to be shown to the user client-side so as not having to wait for a postback each time.I have the ValidationPropertyAttribute("value") set at the top of the control. However it is still being completely ignored by the validation controls. I have found the following from microsoft, but I'm not sure I'm interpreting it correctly, could someoneIn order to be referenced by a validation control, a control must have a validation property. All controls that can be validated have a ValidationPropertyAttribute, which indicates which property should be read for the purposes of validation. If you write your own control, you can make it take part in validation by providing one of these attributes to specify which property to use.
View 3 RepliesI have 2 custom validator controls on my page but for some strange reason the Custom Validator for FileUpload control works and the custom validator for TextBox control does not work. Here is the aspx code:

<asp:RequiredFieldValidator ID="_rfvFileCv" runat="server" ErrorMessage="Resume; " ControlToValidate="_fileCv" SetFocusOnError="True" ValidationGroup="APPLY">

ErrorMessage="Max file size for documents is 4MB." OnServerValidate="CustomValidator1_ServerValidate" ValidationGroup="APPLY"></asp:CustomValidator>
<asp:TextBox ID="_txtHealthComments" runat="server" TextMode="MultiLine" Rows="5" Width="500" />
<asp:CustomValidator ID="CustomValidator2" runat="server" ControlToValidate="_txtHealthComments"

Here is the code behind:

if (_fileCv.FileBytes.Length > 4194304) {
args.IsValid = false;
} else { args.IsValid = true; } }

I have web form in c# asp.net. I have an textbox where the user can enter some part number. When he click on the search button I would like to do some validation of the search text. It is not possible to use the following charachters (- _ / . spaces). When the custom validation found one of these characters I would like to show some error message (It is not possible to use one of these special characters: -, _, /, , . and spaces.). And than I would like to remove the special characters from the search text and execute a method to search.Can I do it with a custom validation like:
<asp:textbox id="TextBox1" runat="server"></asp:textbox><asp:CustomValidator id="CustomValidator1" runat="server" OnServerValidate="TextValidate" ControlToValidate="TextBox1" ErrorMessage="It is not possible to use one of these special characters: -, _, /, , . and spaces."></asp:CustomValidator>
protected void TextValidate(object source, ServerValidateEventArgs args){ args.IsValid = (args.Value.Contains(""); string newSearchValue = // remove the special characters -, _, /, , . and spaces. // Run the search method without the special character, but show a error message search(newSearchValue);}
