customizing Validation js

Posted By:      Posted Date: September 22, 2010    Points: 0   Category :ASP.Net

Is it possible to customize or change in any way how the Validators render their javascript?  I'd like to either move the script tag out of the form, minify the js, etc. without having to manipulate the DOM.  For each validator control the framework renders something like...

var ctl00_Val = document.all ? document.all["ctl00_Val"] : document.getElementById("ctl00_Val");
ctl00_Val.controltovalidate = "some input id";
ctl00_Val.errormessage = "some error message";
ctl00_Val.display = "Dynamic";
ctl00_Val.evaluationfunction = "CustomValidatorEvaluateIsValid";

I want to either wire this up with jQuery or get it out of the page to lighten it up.  Has anybody done this in the past or have suggestions?

Server side validation of Fileupload control not working



I've tried this method in my code behind to try and validate that the Fileupload control has a file or not. I get the error message the the event "Server Validate" cannot be found. Can anyone tell why? Thanks.

Public Sub CustomValidator1_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles CustomValidator1.ServerValidate

' Get file name

        Dim uploadAvatar As FileUpload = DirectCast(AdvertisementForm.FindControl("uploadAvatar"), FileUpload)

        Dim UploadFileName As String = uploadAvatar.PostedFile.FileName

        If UploadFileName = "" Then
            ' There is no file selected
            args.IsValid = False
            Dim Extension As String = UploadFileName.Substring(UploadFileName.L

VS 2010 HTML validation "in CSS" option - where the hell is it?


In VS 2008 there is a very useful feature of background HTML validation - it checks if CSS class name is valid i.e. it exists in one of the linked css files. But VS 2010 Express does not do that any more. And the relevant setting in Options->Text Editor->HTML->Validation->in CSS is not there. Ok, maybe they made it paid for option? VS 2010 Professional? Not there. Or maybe VS 2010 Ultimate? Not a trace.

1. am I blind?

2. they decided it is too convenient to use and removed it?

3. they will "introduce" it in SP1?

What is going on? That one thing made me move back to VS 2008 web developer.


Customizing the UI around the Filters


I have started working on a new project and thought it would be a great idea to dig into the latest version of the Dynamic Data framework that shipped with VS2010.  For the most part, I am impressed, it seems to be pretty easy to extend and create a rich and flexibile UI -- at least that is what I thought until I got to working on a better layout for the filters.

The situation is this:

I have a table with 25 columns and I need to display around 10 different filters (basically and interactive report) -- the filters are of various types.

The problem:

How in the world do I custom the UI layout of the filters.  It seems that with the latest QueryFilterRepeater control we have been left with almost nothing to work with (outside of turning filters on/off and setting the FilterUIHint).  What if I wanted to wrap all of the filters in an expand/collapse region and then inside of that have then sitting in a table of no more than 4 columns (so with 10 filters I wold have 3 rows). 

I have tried extending the QueryFilterRepeater but it seems like there is nothing in that class that we can work with (the data binding events are not even used).

Am I missing something, or am I just out of luck right now?

User validation Issue in xlsx file



I am validating user from Login.xlsx file. It was working fine by validating email and password from that file. For testing i got new file same contents of file but added some more user names.

So after that when i validating the user i am getting the following error "Data type mismatch in criteria expression".

But when i replaced the new to old one it is working fine. The contens of both files are the same. So why this kind of error happened.


set messageTemplateResourceName from resource file in Validation appication block.



  I am using Validation application block in my project and want to set validation message from resource file, but not able to do that. I tried giving the path of resource file in messageTemplateResourceType and name of resource in messageTemplateResourceName. But it did not help as I only receive the message if I have set something in messageTemplate even after setting the resource file.

Here is my code:

<validator lowerBound="1" lowerBoundType="Inclusive" upperBound="250"
              upperBoundType="Inclusive" negated="false" messageTemplate=""
              messageTemplateResourceType="Asurion.jCare.Common.Resources.UIResources.PerilTypeAndDetailsSection, Asurion.jCare.Common.Resources, Version=, Culture=neutral, PublicKeyToken=null"
              tag="" type="Microsoft.Practices.EnterpriseLibrary.Validation.Validators.StringLengthValidator, Microsoft.Practices.Enterpris

Localize framework message from xml validation error


I need to validate an XML through XSD. I am using XMLReader (with XmlReaderSettings and 

Validation_EventHandler to do it). Depend on users preference, I would like to change the output message generated by  Validation_EventHandler in french or english.

Any idea on how to perform this?
