File Uploader

File Selection

The FileUploader widget allows an end user to upload files to the server. This demo illustrates the use of the FileUploader within a web page. To select a file using the Open file dialog, click the Select photo button. Note that the Open file dialog only accepts image file types as the accept configuration option of the FileUploader is set to "image/*".

IMPORTANT: This demo does not actually upload the selected file. To upload a file, submit the form. The form element should contain the action attribute, which holds the URL of the page providing server scenarios for saving uploaded files.
Copy to Codepen
window.onload = function() { var viewModel = { firstName: { value: "John" }, lastName: { value: "Smith" }, fileUploaderOptions: { selectButtonText: "Select photo", labelText: "", accept: "image/*", uploadMode: "useForm" }, buttonOptions: { text: "Update profile", type: "success", onClick: function(){ DevExpress.ui.dialog.alert("Uncomment the line to enable sending a form to the server.", "Click Handler"); //$("#form").submit(); } } }; ko.applyBindings(viewModel, document.getElementById("form")); };
