ak-upload bind selected files into viewmodel

[enrico-padovani]

Hi,

I'm doing something like this:

<ak-upload k-multiple.bind="true" 
           k-async.bind="{ autoUpload: false }">
    <input name="files" type="file" files.bind="files" />
</ak-upload>

In the viewmodel I have the files property which is populated correctly only the first time. If I change the selected files, it will not be synchronized. It seems that's the files.bind="files" fires one time.

Should this be working?

I'm not sure how Kendo handles changes to files internally. I'd recommend using the API functions to do file operations

I'm closing this since It's not a bridge fault. When adding files kendo keep adding input elements, so this is probably causing aurelia binding not working as expected.

The only way I managed to make it work, is to use kendo events and keep track of files manually like so:

<ak-upload k-multiple.bind="true"
           k-async.bind="{ autoUpload: false }"
           k-on-remove.delegate="removeFiles($event.detail)"
           k-on-select.delegate="addFiles($event.detail)">
     <input name="files" type="file" />
</ak-upload>

public addFiles(e) {
    for (const file of e.files) {
        this.files.push(file.rawFile);
    }
}

public removeFiles(e) {
    for (const file of e.files) {
        this.files.splice(this.files.indexOf((file.rawFile)), 1);
    }
}

Maybe it could be done by implementing a custom attribute to avoid repeating this code over time.
