Disabling Submit Button In Web Application With JavaScript Breaks BlackBerry Submission?
Apr 12, 2010
The following code is being used to disable a Submit button once it has been clicked. This works great on desktop browsers and most BlackBerry mobile browsers.
Submit.Attributes.Add("onclick", "javascript:this.disabled=true;" +
ClientScript.GetPostBackEventReference(Submit, null));
when using a BlackBerry Storm clicking the submit button causes the device to just reload the page. If I remove this code the Storm browser submits the page just fine. I need to disable the button when the browser is capable of doing so but do not want to affect browsers that are not JavaScript capable.

1. I want to stop multiple clicks on a submit button. Once the user has clicked the submit button,he has been redirected to next page. but he should not be allowed to click submit button multiple times.
2. once the user has gone to the next page, he should not be able to come back to previuos page,; if at all he comes back-- all the form fields should get cleared. how?

I'm working on an ASP.NET application. Currently when the user clicks "Save" on an item, we disable the Save button, change its text to "Saving..." and so on. This works fine, because the button causes a postback which results in a new page being loaded, on which the Save button is no longer disabled.
We now want to apply this to other actions: Publish (not much different from Save), Import (again, much like Save, but based on data the user has uploaded in a previous step), Export (downloads an XML file to the user) etc.
Export is causing me problems - the button stays disabled. I think this is because the server sends back an XML file rather than a new web page, and so the browser just displays the same page.
The server-side code is along the lines of
Response.Clear();
Response.BufferOutput = true;
Response.ContentType = "text/xml";
Response.AppendHeader("Content-Disposition", "attachment; filename=" + whatever);
[push file contents into Response.OutputStream]
Response.End();
a way of making the server send a fresh page back in the response as well as the XML, thus re-enablnig the button in the same manner that the other pages do, ora way of getting the browser/JS to re-enable the button once the file has been sent.

For the release of Microsoft MVC 2.0 RC2, can someone go into further detail on the following BUG/FIX: You can now programmatically disable client validation for a submit button (an input elements whose type attribute is set to "submit") even if the button does not have its name attribute set, whereas before it required the name attribute.Does this apply to the HTML Helper Submit Button or the input submit button? How would I disable client validation for a submit button? I tried using the htmlAttribute causesvalidation="false" on a HTML Helper Submit button and it did not work.

I am running into a strange problem I don't fully understand. The main symptom is that when I double click a link (that points to a controller action) in my MVC application, my database server connection gets blown, and I get the error :
Execution of the command requires an open and available connection. The connection's current state is broken.
If I step through starting at a breakpoint at the top of the controller action, it will step down a couple lines and then jump back up to the breakpoint. Somehow the first request isn't executing fully before the second one gets there, and somehow my database connection breaks when it gets to any query. Every time this happens, I have to restart the application server.
It was happening intermittently at first, but the double clicking of links seems to reproduce it everytime. Does this happen to anyone else? What am I missing here?
Update :
A.) I incorrectly tagged this as Linq-to-sql when we are actually using Linq-to-entities.
B.) The connection object is defined as a member variable of the controller :
[Code]....
I noticed in some of the asp.net tutorials they declare the variable in the same spot but have a separate constructor for the controller where the db object is initialized. Does this make any difference?
C.) The problem is not only with the double-clicking as described above. The connection breaks at other seemingly random times; I cannot seem to reproduce the error consistently (even double-clicking does not always break it). Restarting the web site usually fixes it, although sometimes I have to restart the host machine. After its back up, repeating the same sequence of actions usually does not reproduce the same error!
Maybe there's something I don't understand about setting up my linq-to-entities classes or the nature of the database connection. Does anyone have any thoughts? I really don't even know how to investigate this one!

How would i go about doing this?
I am writing if value_changes then modalpop.Show but this does not work if there is other code within the button submit.

[URL]
I'm using the code the above and running into an error i can't quite figure out. Maybe its something simple or maybe it's something that can't be done. Not sure.
I created a user control (button) that references a javascript file like this:
string url = ResolveClientUrl("./Scripts/main.js");
function SubmitButton_Click(e) {
try {
var src = typeof (event) != 'undefined' ? event.srcElement : e.target;
[Code]....
The error that i am running into is this:
The buttons in the update panel work everytime without any problems. When i click a button in the update panel and then click a button outside the update panel it chockes on this line of the above javascript.
src.aspnet_onclick();
The value of aspnet_click() is 'SubmitButton_Click(e)'. This is incorrect which causes it to choke.
The value should be 'onclick(event)'
For some reason when click the button inside the update panel and then the button outside the update panel causes this javascript error but I am not sure why the aspnet_onclick() is incorrect.

I have a page with multiple textboxes and each has a button associated with it. This works as a search 'hub', I suppose, where the user can search by ID, name etc. When entering a search term for e.g. name however, pressing enter 'clicks' the very first button on the page (ID search), causing an error if the associated textbox is empty (which it would be if someone meant to search by name). I have attempted to rectify this using JQuery, and have written the following:
$('input:text').click(function (e) {
e.preventDefault();
$(this).next('input:button').focus();
});
I'm simply using the click event so that I can monitor where focus is redirected, but eventually I would use .keypress. However, nothing happens upon clicking a textbox and I can't see for the life of me what is wrong with the JQuery. To elaborate on the problem, the .NET code used looks similar to the following throughout the page.
<tr>
<td style="width:100">Company ID</td>
<td style="margin-left:3px;">
<asp:TextBox ID="...TextBox" runat="server" Width="230px"></asp:TextBox>
</td>
<td>
<asp:Button CssClass="Button" ID="...NameSearch" Text="Search" runat="server" /></td></tr>
This is generating this (view source):
<td><input name="...TextBox" id="...TextBox" style="width: 230px;" type="text"/></td>
<td><input name="...NameSearch" class="Button" id="...NameSearch" onclick="javascript:__doPostBack('...NameSearch','')" type="button" value="Search"/></td>

I got an application to support, it's an asp.net web project, on the 1.1 dot.net framework.It's all ok, with the application, when it runs on web brownsers, and when I try run it from inside a blackberry mobile phone it runs ok too, except when I try to execute an Response.Redirect("some_page_of_my_app.aspx").It always goes to the default page (login page), and ask for login again, and I never can do a redirect.

I've built a ASP.NET webservice and I'm trying to access it from a Blackberry. I've been testing it out with multiple devices and the simulator and it works fine, but there's just the one Blackberry 9000 (It's not the model, I've tried it out with another Blackberry 9000), and it's stuck waiting for a response from the server. Relevant section of the code that accesses this -
System.out.println("IN ntwk access thread, start point");
HttpConnection connection = (HttpConnection)Connector.open(serviceURL + WSNAME);
connection.setRequestMethod(HttpConnection.POST);
connection.setRequestProperty("Content-type", "application/x-www-form-urlencoded");
connection.setRequestProperty("Content-length", Integer.toString(postData1.length));
OutputStream requestOutput = connection.openOutputStream();
requestOutput.write(postData1);
requestOutput.close();
final int responseCode = connection.getResponseCode();
if(responseCode!= HttpConnection.HTTP_OK) {
//Process the error condition
}
// Request succeeded process the data.
It seems to be getting stuck after connection.getResponseCode(). Is there some way I can verify what's going wrong with this particular device?

I was able to find examples throughout the internet that more or less accomplished what I needed to be done, but now I have run into some problems. I need to be emailed the form data when the users submits it and then the user needs to be redirected to a thank you page, in this case "thanks.asp". I have been unable to get the form to redirect users to the thanks page, and in my efforts I think I might have messed the email process up as well.

Users don't like the fact that the Enter key submits the page. So I am tasked with preventing the submission and changing the Enter key to a Tab to the next field. I have tried many javascript snippets found on the net but none have worked so far. The only one that has even come close to having an effect was e.preventDefault() of the jQuery API, which stops the submit, but nothing I have tried emulates the tab behavior.
e.returnValue = false;
e.cancel = true;
Page still submits with the above in the keydown event handler. Same effect with return false in the keydown event handler. The handler is firing, tested by putting a breakpoint in it with firebug. This needs to work with both IE and Firefox. Don't say "don't do this".
1) I'm already convinced that I shouldn't do it, but it's not a choice that is mine, so the discussion is mute.
2) It would be an answer to the question "Should I do this?", which is not the question that I am asking.

OK, I'm sorry if the tile of the question was unclear, and if you understand what I mean, please don't hesitate to help me think of a better one.
Anyway, I have a <input type="submit"> element for my form, and I want it to return the same URL as the URL of the page the element is on.
Currently, if I click the button, it takes me from /Calculate/Quadratic to /Calculate/QuadraticForm
In my controller for this view, I have the following code:
[AcceptVerbs(HttpVerbs.Get)]
public ViewResult Quadratic()
{
ViewData["Root1"] = "";
ViewData["Root2"] = "";
return View();
}
[AcceptVerbs(HttpVerbs.Post)]
public ViewResult Quadratic(QuadCalc boss)
{
ViewData["Root1"] = x1;
ViewData["Root2"] = x2;
return View();
}
And here is the markup and code for my Quadratic view page, which includes the form which includes the submit button I've been referring to:
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<h2>Quadratic</h2>
<% using(Html.BeginForm("QuadraticForm", "Calculate")) %>
<% { %>
<div>
a: <%= Html.TextBox("quadraticAValue") %>
<br />
b: <%= Html.TextBox("quadraticBValue") %>
<br />
c: <%= Html.TextBox("quadraticCValue") %>
<br />
<input type="submit" id="quadraticSubmitButton" value="Calculate!" />
<br />
<p><%= ViewData["Root1"] %></p>
<p><%= ViewData["Root2"] %></p>
</div>
<% } %>
</asp:Content>
Therefore, all I really want is to have the submit button return the same page, but the HTTP post will aid the application in passing new ViewData. Unless I'm interpreting this all wrong.

i have a form which allows the user to key in the data and then submit.
if everything works well on this action result, then i will redirect the user back to a thank you page.
my problem right now is that when the user click on the back button, they will be able to go back to the form page and the inputs will still be there.
and if the user just click on submit again, i will be getting some potential weird bugs.
so in terms of asp.net mvc, what's the best way to handle users who click on the back button?
