Here is the code I have so far:
[code]....
When I click submit, It does the validation on the server side, I kinda like it to validate on the Client instead of taking a trip to the server right away.
I have recently been investigating methods of creating web-based forms for an ASP.NET web application that can be edited and managed at runtime. For example an administrator might wish to add a new validation rule or a new set of fields.
The holy grail would provide a means of specifying a form along with (potentially very complex) arbitrary validation rules, and allocation of data sources for each field. The specification would then be used to update the deployed form in the web application which would then validate submissions both on the client side and on the server side.
My investigations led me to Xforms and a number of technologies that support it. One solution appears to be IBM Lotus Forms, but this requires a very large investment in terms of infrastructure, which makes it infeasible, although the forms designer may be useful as a stand-alone tool for creating the forms. I have also discounted browser plug-ins as the form must be publicly visible and cross-browser compliant.
I have noticed that there are numerous javascript libraries that provide client side implementations given an Xforms schema. These would provide a partial solution but server side validation is still a requirement.
Another option seems to involve the use of server side solutions such as the Java application Orbeon. Orbeon provides a tool for specifying the forms (although not as rich as Lotus Forms Designer), but the most interesting point is that it can translate an XForms schema into an XHTML form complete with validation. The fact that it is written in Java is not a big problem if it is possible to integrate with the existing ASP.NET application.
So my question is whether anyone has done this before. It sounds like a problem that should have been solved but is inherently very complex. It seems possible to use an off-the-shelf tool to design the form and export it to an Xforms schema and xhtml form, and it seems possible to take that xforms schema and form and publish it using a client side library. What seems to be difficult is providing a means of validating the form submission on the server side and integrating the process nicely with .NET (although it seems the .NET community doesn't involve themselves with XForms; please correct me if I'm wrong on this count).
I would be more than happy if a product provided something simple like a web service that could validate a submission against a schema. Maybe Orbeon does this but I'd be grateful if somebody in the know could point me in the right direction before I research it further.
I've got my validation wired up through my Service layer, and my Birthdate property looks like this.
[Code]....
The client side validation works properly if I input something like `12/12/1990` but when the form is submitted, the server side validation trips and I'm told the entry is invalid. I'm using the jQuery-UI Datepicker to input the date, however when I disable the datepicker, the problem persists.Am I missing something here? I thought the client side and server side would be the same thing.If I remove

Then the form submits. It's obviously something to do with the Regex.
want to know that can we validate a control which is out side a form element in asp.net(server side validation)and outside a form element in html(client side validation) let's take a closer look
<html>
<body>
<input type="text" name="first name"/>
</body>
</html>
can we apply clien side validation on above text box by java script ?in asp.net
<form runat="server">
</form>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
I'm interested in identifying a means to verify the server-side validation is performing as expected, but need to bypass the client-side validation being done using ASP.NET validation controls. To test this, I've tried using the form Poster add-on to Firefox that allowed me to get/modify the page contents and post it, but the .NET framework interpreted the submission as harmful and threw an application error ("A potentially dangerous Request.Form value was detected from the client").I've created a WinForm that includes a WebBrowser control and I'm able to manipulate the contents of the web page and invoke the button click, but am interested in seeing how to allow a postback with invalid input values. I don't want to assume the server-side validation works (even though I do check if Page.IsValid on the server on postback).This submits the web form in the WebBrowseer control and the expected client-side validation fires:
extendedWebBrowser1.Document.GetElementById(formButtonName).InvokeMember("click");
This is how I've manipulated some of the page contents (this just prevents submission):
mshtml.IHTMLDocument2 doc = extendedWebBrowser1.Document.DomDocument as mshtml.IHTMLDocument2;
string html = doc.body.innerHTML;
html.Replace("Page_ValidationActive = false", "Page_ValidationActive = true");
doc.body.innerHTML = html.ToString();
extendedWebBrowser1.Document.GetElementById(formButtonName).InvokeMember("click");
I have been presented with a problem which requires me to print PDF files from a server as part of an ASP.NET web service.
The problem is further complicated by the fact that the PDF files I have to print can ONLY be printed using Adobe Reader (they were created using Adobe LiveCycle and have some strange protection in them).
This piece of code seems to do the trick in the Visual Studio development web server, but doesn't do anything when the site's running in IIS. I'm assuming this is probably some sort of permissions issue!?
Dim starter As ProcessStartInfo
Dim Prc As Process
' Pass File Path And Arguments
starter = New ProcessStartInfo("c:program files...AcroRd32.exe", "/t ""test.pdf"" ""Printer""")
starter.CreateNoWindow = True
starter.RedirectStandardOutput = True
starter.UseShellExecute = False
' Start Adobe Process
Prc = New Process()
Prc.StartInfo = starter
Prc.Start()
What is a good way to display the message "your data has been saved" on screen (server side, not javascript) when a user clicks the Update button in a FormView control? I want the message to have a similar look and feel to the error message that displays when validation fails (only in this case, the message will convey that data successfully saved to the database).
View 2 RepliesI'm using an entity model with metadata annotations. My controller method looks like this...
if (!ModelState.IsValid)
{
return View(model);
}
else
{
UpdateModel(model);
repo.Save();
return RedirectToAction("Index");
}
If I enable client side validation in the view I'll get the error per the Attributes from the metadata class. If I take clientside validation out, error gets thrown from saving to the DB rather than return the view with an Error Summary.
This is the top portion of my view....
<% using (Html.BeginForm())
{%>
<%: Html.ValidationSummary(true) %>
I've tried running without debugging (ctrl + f5) in debug and release mode as well as setting breakpoints and Debugging (f5) but it just seems weird to get Client side validation without server side validation. What am I missing here?
I just want to know how to capture an image using asp.net server side.

I have and problem of validate my element from the out side the form tag.
Here I am describe what I have done and what i need :
[code]...
now this TxtSite element is out side that SiteDetail form and i want to validate this element when i have submit data this validation should be validate.
I am using ASP.NET's server-side validation. In the page_load event I'm calling Page.Validate(), and if Page.IsValid is not true I'm then polling the controls to figure out which ones are not valid, and then determining what actions to take.It would be much easier if each control would raise an event as validation fails, allowing me to take action for that particular control. I'm very much a naive programmer when it comes to validation, but is there a way to extend these controls so that a validation error raises an event?

the problem is that when I click save the first time with wrong data the validation not working but it is working the second time I click save.
Is there any way to add a confirmation dialog to a submit button when the form already has other validation controls and a summary control using "showmessagebox=true"? I tried adding
OnClientClick="return confirm('Are you sure?');" to the submit button, but that seems to block all of the other validation?

should I have to do Server Side code validation in .aspx.cs file also using classes such as RegexStringValidator. Is it not enough to do validation using the above code. Will it work for Server Side also.
I'm using MVC 3 RTM, client side validation has been disabled.I have a simple model with one integer field.Server side validation does not accept numbers including one or more thousandseparators.
It shows: "The value '1,000' is not valid for QuantityInStock".It does not matter what culture I use. Both "1.000" and "1,000" are never accepted.
I'm using DataAnnotations as well as server-side validation logic.
Is there a way to show DataAnnotation's client-side validation errors in the ValidationSummary, as it shows when returning from server validation?
I know I can use ValidateMessage and ValidateMessageFor next to elements, but the spacial design of the form I'm working with doesn't allow for anything other than highlighting the HTML element, however, I would still like to have a message saying what's wrong.
If I place ValidateFor's alongside ValidationSummary in order to mimic a ValidationSummary during client-side validation, they both appear when returning from a failed server side validation.
I have one textbox and I want to allow only integer cannot allow character when I entered character to show the error message , this functionality I want create in server side withou using javascript.
