How can I disable the code behind validation when javascript validation is present? Then if there is no javascript enabled then the code behind validation will do its thing. What I notice is that it's reading the code behind valdiation not the javascript.

View 4 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.
I am having issues correctly setting up reference to javascript code to a custom validator.This is my javascript code in the .aspx page.

The validation is if there is a value present in the first text box then the second text box is required.The page throws an error when the validation should fail, but if I ignore the error the validation works correctly.Do I need to move my javascript to the code behind as well?

View 7 RepliesI 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);}

View 1 RepliesI want the validation condition to be: on a pair of textboxes, to be valid as long as at least one of them isn't empty.
So I put a customvalidator on the 2nd textbox, hooked up to the following server code and client code:
<script type="text/javascript">
function ECPhoneOrEmailRequired(source, args) {
var ecPhone = document.getElementById("txtEmergencyPhone");
var ecEmail = document.getElementById("txtEmergencyEmail");
if (ecPhone.value.length < 1 && ecEmail.value.length < 1) {
args.IsValid = false;
}
else {
args.IsValid = true
}
}
</script>
Protected Sub CustomValidator1_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs)
'args.IsValid
If (txtEmergencyPhone.Text = String.Empty And txtEmergencyEmail.Text = String.Empty) Then
args.IsValid = False
Else
args.IsValid = True
End If
End Sub
From what I can tell thru breakpoints, this code works fine as long as there's something in one of the two textboxes. When both textboxes are empty, the code is never called - and so both boxes empty ends up being allowed.
So what's the correct way to validate one-or-the-other-nonempty condition?
On one page, I have 2 buttons. One that says Clock-in and the other says Clock-out. As of this moment, the application will allow you to click on the clock-in button without having clocked out the previous day and will allow you to click the clock-out without being clocked in. If a user is clocked in and they click the clock-in button again, I would like an alert to pop-up that would say "you must clock out before you can clock in". And if the user clicks clock-out without being clocked in, it should say "you must clock in before you can clock out". I am using VB in the code behind and SQL Server 2005. My current button click events are below:

View 2 RepliesWhat I have is button that should open another page only if textbox length is 8. Javascript must be added from code because it does not simply calls the bla.aspx, it's more like bla.aspx?id=4&code=234 etc etc...
I have this code on server side
button.Attributes.Add("onclick","javascript:window.open(bla.aspx)");
on client side i have
<asp:TextBox ID="policyNumberTxt" runat="server" MaxLength="8" CausesValidation="true"></asp:TextBox>
<asp:RegularExpressionValidator ID="policyNumberTxtRev" runat="server"
ControlToValidate="policyNumberTxt" ErrorMessage="Length must be 8."
ValidationExpression="{.{8}.}" ValidationGroup="bla" Display="Dynamic"></asp:RegularExpressionValidator>
<asp:Button ID="printBtn" CssClass="button" Text="Print" runat="server" CausesValidation="true" ValidationGroup="bla" />
What happens is that when I click the button page bla.aspx opens, and even postback is trigered. Validator is showing the message, but page is opened and postback trigered.
How to handle this? Validation is broken...
For some reason fields named with '.value' or .anything does not generate client validation. For example this code:
@Html.TextArea("ContentObjectFirm.Description")
generates this:
<textarea rows="2" name="ContentObjectFirm.Description" id="ContentObjectFirm_Description" data-val-required="Firm description is required" data-val="true" cols="20">
I have a form that I have been getting submissions that have punctuation and special characters that trigger the potentially dangerous Request.Form value error. I have been trying use the httpUtility.htmlencode and Server.htmlencode method to sanitize textboxes and textareas.All my tests do not fire because the built-in request validation of the 4.0 framework prevents the code-behind from executing to perform the sanitization. I have included the ValidateRequest in the page header but no matter what I set it too it still does the same thing.
This is the code I have so far.
Session("RequestID") = Server.HtmlEncode(txtRequestID.Value)
Session("FirstName") = Server.HtmlEncode(txtInstFirstName.Text)
Session("LastName") = Server.HtmlEncode(txtInstLastName.Text) [code]....

I have just started using MVC2 in VS2010, and I noticed that on the Register page DataType.EmailAddress doesn't actually do any validation, so it does not check whether or not the Email Address entered is valid. Should I write some email validation code in the HttpPost Register method of my AccountController, or is there another way to do this?
View 1 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.

[Code]....
Then in the content page I have various controls with validation and a validation summary. I have few custom validators on the content page like below:
[Code]....
which uses the clientvalidationsfunctions which set the validity of the page.Now when I leave the search box in the header blank and I click the submit btn in the content page it posts me back to same (source) page and while debugging I find that the Page.IsValid is false. But if I write something in the search textbox in the master page and the fill the required fields in the content page and click the submit btn in content page it works fine. Why is that so? My validation groups are different on master page and content page.
