In this blog post I am going to show you how to overcome this limitation, as well as how to validate the file size and type on the client before submitting it to the server. $("#f_UploadImage").I bet that most of you have faced this common problem: “How to upload large size files (above 4MB) in ASP.NET?” As you know, the default maximum file size allowed in the framework is 4MB and this is to prevent service attacks like submitting large files, which can overwhelm the server resources.

Now we call this function on a File Upload control change event.i.e. * Note: The contentType and processData are set to false which is important. $("#myUploadedImg").attr("src", my_path) Now we create a common function sendFile() in which we add the file content to FormData's collection and making a jQuery Ajax call //*įormData.append('file', $('#f_UploadImage').files) Here now we add a file input tag (file upload control ), and an image tag.īrowse control to select the image file, and when the image gets uploaded will set the newly uploaded image path/source to our image control, which we have already added on our Asp.net Web Page.įinally, this is how our HTML looks like as written below.

Have you ever upload files without using any plugin? I must suggest you to check how to preview an image before upload it to the server using jQuery and HTML5 FileReader API. This means we can upload image files without the page refresh or no postback in Asp.net C#.įor this, we use a generic handler ( ashx file ) and also display a progress bar while file uploading.i.e displaying percentage while image gets uploaded. i.e upload an image file from client-side with jQueryajax call.
