@sanjeev-rajput here are what we are doing in our app to upload file
Step 1:
In our view we are declaring following beads:
```
<fx:Declarations>
<js:FileProxy localId="fileProxyUpload">
<js:beads>
<js:FileBrowserWithFilter localId="fileBrowser"
filter=".yourfileextension"/>
<js:FileModelWithParams localId="fileModel" />
<js:FileLoader localId="fileLoader"/>
<js:FileUploaderWithResponseData
id="fileUploader" contentType=""/>
</js:beads>
</js:FileProxy>
</fx:Declarations>
```
In the background FileUploaderWithResponseData is doing what you are
searching for:
https://github.com/apache/royale-asjs/blob/36265208992aea285ca3e7809afd546512065285/frameworks/projects/Network/src/main/royale/org/apache/royale/file/beads/FileUploader.as#L83
Step 2: Register on event "modelChanged" using fileProxyPload
```
fileProxyUpload.addEventListener("modelChanged", onFileModelChanged);
private function onFileModelChanged(event:Event):void
{
fileModel.addEventListener("blobChanged", onFileBlobChanged);
fileLoader.load();
}
private function onFileBlobChanged(event:Event):void
{
fileModel.removeEventListener("blobChanged", onFileBlobChanged);
//fileModel.name; - You can store somewhere if you need your file name
}
```
Step 3:
We have Button where on click we do browse. It opens for you window to
pickup the file.
```
private function onButtonClick(event:MouseEvent):void
{
fileBrowser.browse();
}
```
Step 4:
We have button called "Upload" - where you basically starting submitting
your data to your server side or wherever you want
```
private function onFormSubmitClick(event:MouseEvent):void
{
// to-do
// do validation check here
if (!fileModel.blob)
{
view.uploadFileResult("Please attach an .id file to continue.");
return;
}
//fileModel.setParam("fileparam", "yourparams")
fileUploader.upload("serverurl");
}
```
Note that we have special bead which extends FileUploaderWithResponseData -
I will add that bead to Royale so other could benefit. What we do in this
extension is we are sets to true `xmlHttpRequest.withCredentials = true;`
I hope this helps.
