Below is part of my codes in C#, it suppose to send email, show the msg box, then direct to 'Multihotelbook.aspx' page, but the direct to the page without showing the msgbox. i dont know why. need help
emailClient.Send(message);
// Response.Write("<script>window.alert('Email sent')</script>");
//ClientScript.RegisterStartupScript(typeof(Page), "myscript", "<script>alert('Email sent');</script>");
// System.Windows.Forms.MessageBox.Show("Email sent");
// MessageBox.Show("Email sent");
// MessageBoxResult result = MessageBox.Show("Email sent", "Confirmation");
//ClientScript.RegisterStartupScript(typeof(Page), "myscript", "<script>alert('Email sent');</script>");
//ScriptManager.RegisterStartupScript(this, typeof(string), "Message", "confirm('Email sent');", true);
//ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "KEY", "alert('Email sent')", true);
Page.ClientScript.RegisterStartupScript(typeof(string), "alert", "<script>alert('Email sent')</script>");
Response.Redirect("Multihotelbook.aspx");
This... looks like ASP.NET code. There is no MessageBox in ASP.NET. Notice that you had to fully reference System.Windows.Forms, which I imagine you also had to add as a reference. Windows Forms and ASP.NET are two very different things.
What exactly are you trying to accomplish? Showing a JavaScript alert()? If that's the case then you can just include some additional JavaScript code in the response.
Except... you're also doing this:
Response.Redirect("Multihotelbook.aspx");
Which means that the response to the client is being clobbered by a header which tells the client to go to Multihotelbook.aspx. So the client never sees anything else you're including in the response, basically anything in RegisterStartupScript.
After this code executes, the client is going to end up on Multihotelbook.aspx. Unless there's a JavaScript alert() on that page, the browser won't show one.
One approach you could try is to pass a flag to Multihotelbook.aspx, something like Multihotelbook.aspx?emailSent=true and in the Page_Load of that page check for that value and, if it's set to true, include JavaScript code in the page to show the alert() (probably using RegisterStartupScript like you're already trying).

I have the following scenario:
An datatable with some editable columns which validate for input on the client with the webix rules. There are columns though, that cannot be validated on the client, but on the server only (ie for unique id/code).
An approach would be to create a rule and validate with webix.ajax in synchronous mode that I would prefer to avoid this at all means.
I thought I could validate on 'save'. The server can return a status response with error or success. I can catch this with onAfterUpdate event of the datatable (correct me if there is a better way, but it works this way).
At this point, I would like to display a validation error on the datatable if the server script returns an error status and mark the row (and possibly the corresponding column/cell) with error.
I thought I could use the callEvent method on the datatable and fire a onValidationError event but I didn't manage to make that work.
save: {
url: "save.php",
autoupdate: true,
on:{
onAfterUpdate:function(response, id, details) {
if (response.status == 'error')
myDataTable.callEvent('onValidationError');
}
}
}
The documentation states that I can pass some parameters to the event from callEvent but I could not find any specification on the docs. The code above does not work (the event is not fired).
So the question is: How can I fire a onValidationError event for the datatable using callEvent?
or what would be another approach to use webix to show the error on the datatable with validation on the server side?
Thank you.
Instead of calleing onValidationError event you can use
//mark cell, call after error response
myDataTable.addCellCss(id, columnId, "webix_invalid");
//remove mark, call after success response
myDataTable.removeRowCss(id, "webix_invalid");
which will mark the cell as non-valid.
On a side note, if you want to trigger some event with parameters, you can use code like next. Just beware that triggering an event is not a good way to change the component's state ( it can be used to trigger your own event handler though )
myDataTable.callEvent("event name", [param1, param2, param3])

So as recommended I'd like to use RestSharp to handle REST web service. I am developing iOS and Android application and I would love to make PCL that makes requests to the service and just returns parsed results (eg. array of User objects).
So how do I get RestSharp in my PCL, tried NuGet, components are not for PCLs and seriously bad would be to just download source files and copy them in the project, I want to keep some dependency management in place.
What is the best practice? Am I looking at this problem at wrong angle?
RestSharp doesn't support PCLs. I'd suggest checking out PortableRest, or just using a combination of HttpClient and Json.NET.
I use dependency injection so I can support non-PCL JSON parsers. I also plan to give the native HttpClient wrappers from the component store a try. By using non-PCL code you will gain quite a lot in performance compared to Json.NET etc.
Link to source code
Text library has serializer interfaces, Web has the IRestClient.
Modern HTTP Client from the component store.
Below modifications worked for me and will be glad if it works out to you.
Try using modernhttpclient in your PCL. And inAndroid project ensure you have the below packages.
Microsoft.Bcl.Build
Microsoft.Bcl
Microsoft.Net.Http
modernhttpclient
Along with that in application manifest under required permissions give permissions to the below.
Access_Network_State
Access_wifi_state
Internet
Ideally when you try to add Microsoft.Bcl into your Android project targettting monoandroid it will throw out error, so try to add the nuget refrence in the above order.
I developed a really simple REST client to perform Http requests easily. You can check it on my Github repo. The API is really simple:
await new Request<T>()
.SetHttpMethod(HttpMethod.[Post|Put|Get|Delete].Method) //Obligatory
.SetEndpoint("http://www.yourserver.com/profilepic/") //Obligatory
.SetJsonPayload(someJsonObject) //Optional if you're using Get or Delete, Obligatory if you're using Put or Post
.OnSuccess((serverResponse) => {
//Optional action triggered when you have a succesful 200 response from the server
//serverResponse is of type T
})
.OnNoInternetConnection(() =>
{
// Optional action triggered when you try to make a request without internet connetion
})
.OnRequestStarted(() =>
{
// Optional action triggered always as soon as we start making the request i.e. very useful when
// We want to start an UI related action such as showing a ProgressBar or a Spinner.
})
.OnRequestCompleted(() =>
{
// Optional action triggered always when a request finishes, no matter if it finished successufully or
// It failed. It's useful for when you need to finish some UI related action such as hiding a ProgressBar or
// a Spinner.
})
.OnError((exception) =>
{
// Optional action triggered always when something went wrong it can be caused by a server-side error, for
// example a internal server error or for something in the callbacks, for example a NullPointerException.
})
.OnHttpError((httpErrorStatus) =>
{
// Optional action triggered when something when sending a request, for example, the server returned a internal
// server error, a bad request error, an unauthorize error, etc. The httpErrorStatus variable is the error code.
})
.OnBadRequest(() =>
{
// Optional action triggered when the server returned a bad request error.
})
.OnUnauthorize(() =>
{
// Optional action triggered when the server returned an unauthorize error.
})
.OnInternalServerError(() =>
{
// Optional action triggered when the server returned an internal server error.
})
//AND THERE'S A LOT MORE OF CALLBACKS THAT YOU CAN HOOK OF, CHECK THE REQUEST CLASS TO MORE INFO.

I have below code in jsp to create a dataTable. I am using bProcessing as true which displays the 'processing' indicator till i get the
data from the server. I want to show the message as "loading data.." instead of 'processing'. I tried using sProcessing as suggested on various
sites but it does not work?
customersTable = $('cutomer').dataTable({
"sAjaxSource": "ajax url",
"bProcessing":true,
"bDeferRender": true,
"sServerMethod": "POST",
"oLanguage": {
"sProcessing": "loading data..."
}
});
"oLanguage": {
"sProcessing": "loading data..."
}
works for me and also suggested in dataTable Api's http://datatables.net/ref. Just check whether you are putting at right place. Otherwise you can also try fnPreDrawCallback and fnDrawCallback
You could try sLoadingRecords instead of sProcessing, as sLoadingRecords deals with loading data, and sProcessing deals with datatables sorting/searching local data. Since you are using server side processing, I'm don't think sLoadingRecords will work for you, but it might actually change the text for you.. Let us know it it works for you.
Here's the info on sLoadingRecords from the DataTables website.
When using Ajax sourced data and during the first draw when DataTables is gathering the data, this message is shown in an empty row in the table to indicate to the end user the the data is being loaded. Note that this parameter is not used when loading data by server-side processing, just Ajax sourced data with client-side processing.
And for sProcessing
Text which is displayed when the table is processing a user action (usually a sort command or similar).
Hi i'm new to Jquery mobile,have some servlet which evaluates username and password from login.html page as,
if(un.equals("user1") && pd.equals("password1")){
RequestDispatcher rd=request.getRequestDispatcher("welcome.html");
rd.forward(request, response);}
else {
RequestDispatcher rd=request.getRequestDispatcher("loginfailed.html");
rd.forward(request, response);}
}
i
what i'm trying is when login fails loginfailed.html should open as a popup dialog showing login failure notice example here. Pls help me to do this..
I've been using this:
http://dev.jtsage.com/jQM-SimpleDialog/
Much easier to open from within javascript than the default jquery-mobile dialog, plus it looks like a dialog in that it does not take up the whole page.
I have a form that lets users select checks, and when submitted, creates a PDF, which opens in a new browser tab. It doesn't have any branding, and will probably open in a plugin anyway, so I don't want it taking over my site's tab. So I set the form's target to _blank.
But it's possible for the user to submit the form without enough information to create the PDF, in which case I flag the error (server-side) and re-render the form. But because I set the form's target, this re-render opens in a new tab as well, and that's not what I want - in this case, I want it to behave as if target were _top.
So the question is: Can I change the browser's rendering target server-side?
Yes, I know that this can be done with client-side JavaScript, but JS annoys me, and I have to do the validation server-side anyway. I may end up having to use it, but please don't suggest it as an answer - I'm more curious if what I'm attempting can even be done.
PS: I'm on Ruby on Rails 2.3.8, in case anyone knows a framework-specific solution.
A workaround on this problem would be to use the content-disposition header on the pdf, in order to force the file to be downloaded, and avoid the whole "target" approach..
Content-type: application/pdf
Content-Disposition: attachment; filename="downloaded.pdf"
No. This is a purely client-specific feature. As a matter of fact, it's quite possible to get a browser that supports only one window and where the target attribute would have simply no effect. There were even efforts to make this attribute disappear from future HTML standards completely (for instance, the XHTML branch had no such attribute).
The only overlap that I can think of between HTML and HTTP are the <meta http-equiv> tags (where HTML can affect otherwise HTTP-controlled behavior). HTTP is a transfer protocol, designed to work with about just any kind of data. Letting it control presentation would be a pretty terrible mix of concerns.
Fortunately, we live in a JavaScript-enabled world. It is rather easy to validate a form using an AJAX request, especially with libraries like jQuery.
For instance, this script performs a POST request to an URL (in this case, /pdf/validate) and expects the page to send back "ok" (if everything's good) or something else if there was an error.
<form method="post" action="/pdf/send" id="pdf-form">
<!-- form stuff here -->
</form>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$(document).ready(function()
{
// set to true if we are to bypass the check
// this will happen once we've confirmed the parameters are okay
var programmaticSubmit = false;
// attach an event handler for when the form is submitted
// this allows us to perform our own checks beforehand; we'll do so by
// cancelling the event the user triggered, and do the submit ourselves if
// we detect no error
$('#pdf-form').submit(function(event)
{
if (!programmaticSubmit)
{
// first off, cancel the event
event.preventDefault();
// do an AJAX request to /pdf/validate
$.ajax("/pdf/validate", {
type: "POST",
data: $(this).serialize(), // send the form data as POST data
success: function(result)
{
// this gets called if the HTTP request did not end
// abnormally (i.e. no 4xx or 5xx status);
// you may also want to specify an "error" function to
// handle such cases
if (result == "ok")
{
// since the server says the data is okay, we trigger
// the event again by ourselves, but bypassing the
// checks this time
programmaticSubmit = true;
$(this).submit();
}
else // something went wrong! somehow display the error
alert(result);
}
});
}
});
});
</script>
