I believe it would be.Class ParentComponent extends React. To submit the grid, you may need to ensure it is stringified. The IFRAME trick is needed because all the scripts running in the window that is doing the upload will hang until the the request is completed at which time the file is fully uploaded. You shouldn't though try to show this field contents in a grid cell though.

You can probably store the file as-is (binary and all) in a field as long as you don't specify an explicit type for the store's model field.

The documentation provided above should help you with that ( MDN docs). The script from the default url has a 5Mb upload limitation for. If the browser doesnt support file saving then those functions will upload the file content to the server address provided in url. Call saveAs to save text files or saveBinaryAs to save binary files. It allows file saving using browser features or remote server calls. Now, as far converting the file contents, it is beyond the scope of Ext.NET. This singleton has methods for file manipulation. If you just want to hit the file data while not touching the field, you can get the internal file input field (beware, dragons ahead!) via the undocumented, unsupported (may break at any time between upgrades without any warning) fileInputEl.dom reference.Īs an example of getting the field from actual code, in the example Form > FileUploadField > Basic, you can get the input field via either:Īpp. (unsupported)Īpp.BasicField.extractFileInput() (supported, resets the field on call) Don’t rely on the load event to know when the upload has finished. If and when progress is triggered, remove this pseudo-progress element and replace it with a real progress bar. The drawback of this approach would be the input field is reset once you call this method (as for emulating a file upload success - which may just be the desired behavior in your case). For example, an indeterminate progress bar or a spinner. The "supported" way to get the internal file input field from the Ext.NET component would be the extractFileInput() method. MDN has good documentation on the file input element (and File API) you should understand in order to attain your objective. Then just access the field's internal input type=file HTML element and extract the file contents and add the file to the grid. You can either bind a "send to grid" button to serve as a "upload" button (to assign the file to the grid), or bind the field's change event. A file upload field which has custom styling and allows control over the button text and other features of like empty text.It uses a hidden file input element behind the scenes to allow user selection of a file and to perform the actual upload during form submit. Yet, I believe you can easily accomplish this task with the FileUploadField component. I am afraid we don't have any cooked example on the exact task you want, and not that native feature from Ext.NET or its underlying framework (Ext JS).
