JQuery :: How To Upload Files In Browser Cache To Get File Size On Client Side

Apr 1, 2011

My requirement is to get the file size in client side. there is no problem in FF but in IE you can't do that unless u r using an activeX object. So we thought of putting it in browser cache and reading the file size from there and when we post it to the server we will be taking it from the cache and send it to the server.

Maintain Scroll Position After Client-side Validation Fails?

Jun 29, 2010

I've got an ASP.NET webform with asp:TextBox and asp:RequiredFieldValidator at the bottom of the page. If client side validation fails on form submit - the page scrolls all the way up.

I'd like to maintain the scroll position on failed client-side validation.

Jan 2, 2010

I'm using the ASP.NET login control and I'm displaying a jQuery throbber when the submit button is clicked. This works fine, but the throbber is visible if client side validation fails and the button is invisible, so the user cannot re-submit the form. How do I hide the throbber if client side validation fails?

How To Extend Server-side Validation Controls To Raise An Event If Validation Fails

Feb 23, 2010

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?

How To By-pass Client-side Validation To Verify Server-side Validation

Mar 1, 2011

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");

Mvc2 Data Annotations Validation (Client Side Works, Server Side Doesnt?

Aug 12, 2010

I'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?

AJAX :: Refresh ListView After Async File Upload?

Jun 23, 2010

I'm trying to combine nested listviews, updatepanel and asyncfileupload, but have run into some problems. I'm having a main listview listing some projects, and in each project I have a nested listview listing some images in that project. I also have an insertitemtemplate, for inserting new images. This template contains an asyncfileupload control. Everthing is contained in one large UpdatePanel, to enable smooth editing of the images and their associated information.

Problem 1:

The fileupload is complete now, and the file uploads as I expect. In the AsyncUploadCompleted event I'm also inserting the uploaded image to the database. So far so good. But when the upload is done, I want to be able to see the newly updated record in my nested listview. But this is not the case. I'm not able to DataBind the listview in the AsyncUploadCompleted, because that throws an exception saying "The control collection cannot be modified....". So, how do I manage to do an async update of the nested listview, showing the new record?

Problem 2:

When deleting items from my nested listview, after the async update the listview shows up without any items except the InsertItem. The items are not removed, a refresh of the page brings them back. Why is the databinding lost during the async postback?

Button Click Event Still Firing Even Through Custom Server-side Validation Fails?

May 27, 2010

I am having a problem where my button click event is still firing even though my custom server-side validation is set to args.IsValid = false. I am debugging through the code and the validation is definitely being fired before the button click, and args.IsValid is definitely being set to false once the custom validation takes place, but it always makes its way to the button click event afterwards.

Javascript - User Control With Client + Server Side CustomValidation; Wrong Client Side Validator Is Picked

Nov 23, 2010

I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)

<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...

There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)

<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...

There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.

<script type="text/javascript">
//<![CDATA[
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");

[code]...
Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.

C# - Show Only Client-side Validation With Client And Server Validators?

Dec 12, 2010

If I have something like the following:

<asp:TextBox id="test" runat="sever"></asp:TextBox>
<asp:RequiredFieldValidator runat="server" ControlToValidate="test"
ErrorMessage="Required"></asp:RequiredFieldValidator>
<asp:Label runat="server" id="lblStatus"></asp:Label>

if in the code behind, I set the label to "You must enter a value if the textbox is empty" to validate it on the server side and this is fine, but if javascript is enabled, I don't want to show the client side validation and the server side label together. Is this something where I would just have to disable the client-side validators if javascript was enabled?

Can An Iframe Load Its Contents At The Server Side Rather Than Client Side

Dec 21, 2010

I know that setting runat="server" and specifying an id for an iframe control, makes it accessible on the server side but what I need is that the iframe source contents get loaded at server side not client side.Is it possible?Why do I need it this way?

Currently my iframe source site is configured for ntlm authentication and sso which means it would read my windows credentials whereas I'd need it reads the credentials provided by the site which hosts that iframe.

AJAX :: How To Upload A File From Server To Client Without Attaching It To The Response

Mar 22, 2011

Basically I have to generate a rather large XPS document serverside and send this back to the client.

The issue I have whilst trying to do this is because the XPS document needs to be created on a STA thread, so either the response is sent back before the async operation is complete (in which case I can't attach the file using the transferfile method) OR I have to wait until the Async thread has completed and then I can send the file using the transferfile method (but this leaves the current page locked out for quite a while).

SQL Server :: Uploading .pdf Files With File Upload Control And Then Saving To Database

Oct 25, 2010

I'd like to allow users to upload a .pdf file via the file upload control (if that's the best method), save the file to the db and then retrieve it so they can click on a link and open the .pdf they've uploaded. I've been looking for a tutorial on how to do this but keep running into methods of saving the file directly on the server in a directory, not in SQL server (using Linq and VB by the way)

C# - Using SoapExtensionAttributes On Client Side With Async Web Methods?

May 6, 2010

I implemented custom soap extension and registered it into client application configuration file. It works fine.

(I would like to implement progress bar functionality like [URL]

But I don't like some thing - custom soap extension is invoked by every call of my web service. In order to fix this situation (call WS just by required methods) I implemented custom SoapExtensionAttribute like below:

[AttributeUsage(AttributeTargets.Method)]
public class CustomSoapExtensionAttribute : SoapExtensionAttribute
{
public override int Priority { get; set; }
public CustomSoapExtensionAttribute() : this (1)

[Code]....

I added this attribute to required methods of web service proxy classes (and removed registration into client configuration file).

My soap extension doesn't invoke when required web methods are calling. Anotherone, I don't know it is important or not - my required methods are async web methods.
