We are using asp.net and c#3.5 implementing a website using quite a lot of jQuery. We would like to download an img from the browser window, but (and here's the trick) in a button click (in addition to right click save as)...
Before we get into it, I should state that we know that this is an img tag and from the front end, we can easily download the image using right click save as. The only reason we wish to download the image from a (say) button click is because across the site we have download buttons for downloadable content (like datatable to excel files and pdfs, etc) and we would preferably like to keep the standard across thewebsite.
We are producing graphs using Microsoft Chart Control which renders the graphs to the screen pretty well. This renders an image to the screen as shown below in an example (using Firebug)
There is a known bug with MS Chart Control that if you store the image in session variables or memory, that the image is only accessible once and not persisted. Described here
We don't have a physical location for the image when it is created (and most often the Chart Control destorys the image).
What we need is some client side method of downloading this image content from the screen as it is rendered, but without having access to the physical image at the back end. We do not want to use the chart control property:
I am new buddy to Jquery. I am using a Jquery image scroller in ASP.net.But In this scroller image path must be set in javascript like an array. For Ex-Car_Image_Sources=new Array( imagearray// NOTE No comma after last line
How can I upload files asynchronously with JQuery?
I have a file upload field, after the image was selected, i make a jquery ajax post to an aspx page's page method. My question is, how can I pass that image via jquery? When I do $(this).val() it only gets the file name. I want to pass the image object itself.
I am using JQuery in my application. I am having a div in my page which will get fill with another page content on a button click.
The following is the code.
$("#dialog").load('Default.aspx?TicketID=15');
Now i am having a button in this Deafult.aspx page which will download an attahchment from the database.
If i write a server side event to download the page is getting postback and the content in the div has gone. So, i have used JQuery Ajax method to download the attachment. But i the attachment is not getting downloaded.
I am using ashx to serve images from a database, is there anyway to have a user click on a link that allows them to download the file on the computer. (IE it shows the Save Dialog) Like you download a file.
Whats the best method to prompt a user to download something? In the past I've used window.open('file.pdf'); but I can see popup blockers having a problem with this. Of course I'll include a manual link aswel.I basically want something like the Microsoft Download page. So whats the script that prompts this?
I am trying to implement a service to download a image file. The code does nothing but upload a file to the response with each client request.
There are no SOAP messages involved but I am planning to implement it as ASP.NET web service. It can also be implement as ASP.NET website but since it has no view (forms, html etc) I planned to implement a web-service.
I have created an ashx handler to render image thumbnails from images in a mysql database. If a file name is passed through querystring, the content disposition filename is set (when user clicks "save as..." the filename appears). The images appear properly and the filename appears when user selects "save as..." but the filetype is listed as unknown and the file that downloads has no type. I have tried adding ".jpg" to the end of the filename in content disposition for lack of anything else to try, but this made every image download as untitled.bmp.
