Would like to be able to change / recall State of expanded / collapsed items in FileManager, similar to how we can with the Grid component using Groups.

On refreshing data from the database, the entire File Manager reverts to all items collapsed, which will be annoying for end users.

State management could also deal with the default view (Details vs Icons) as requested elsewhere for this component.

For true load on demand, the OnRead event should be triggered for:

• PathChanged;
• TreeView expand;
• as many more data-related actions as possible;

Sorry to bother you, but we found a problem when using the FileManager control. When you are in a directory hierarchy Home > Dir1 > DirA > DirX > DirY and you want to navigate to the parent directory say DirX using the breadcrumb, clicking on DirX, FileManager sends you to the root directory. I hope you can help me.

If there are a lot of child folders, the Breadcrumb navigation does not work correctly. The current directory does not respond to the selected one.

The FileManager is not showing icons for video files, e.g. mp4. The icon's CSS class is k-i-video, but it may need to be k-i-file-video.

The workaround is to apply the k-i-file-video icon to k-i-video:

CSS

.k-i-video::before {
  content: "\e93b";
}

Possible to add in the FileManager preview pane, a preview of the actual file, if the file type is simple; i.e. image or video (or pdf); or provide functionality to add preview.

Cheers

If there are many subfolders below a folder the list becomes too long for the TreeView window and gets cut off at the bottom. Apparently, there are some height and overflow settings missing. After some digging around in the rendered HTML and copying some CSS selectors (using F12 on Edge) I got it working with this in my CSS file:

.k-filemanager-content-container > div > div.k-pane.k-filemanager-navigation.k-pane-static > div > div > ul {
    height: 100%;
    overflow: auto;
}
.k-filemanager-content-container > div > div.k-pane.k-filemanager-navigation.k-pane-static > div > div {
    height: 100%;
}

----------ADMIN EDIT----------

In the meantime, here is a possible workaround:

<style>
 .k-treeview-lines {
        height: 100%;
 overflow: auto;
    }

    .k-filemanager-treeview {
        height: 100%;
 }
</style>
