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>

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";
}

When using the FileManager and navigating through directories, the Breadcrumb does not show the path.

I was using the FileManager component for a project and wanted to disable some operations since in my use case, it must not be possible to do them. But I was surprized to notice that this apparently cannot be done. So I suggest to add boolean parameters that will allow to disable the following features:

• new folder
• renaming
• searching
• details pan
• download
• upload
• delete

Of course, the goal here would be to render the user interface accordingly. E.g., if deletion is disabled:

• remove the Delete entry in the right click menu
• and never call the OnDelete event.

I was using the FileManager recently and wanted to make sure the user could only select a single file. I was expecting a parameter to configure that but I didn't find any. I was able to bypass the issue by acting on the value reported by the component but I found it a bit inconvenient.

I think it might be interesting if we could:

• choose if we select one or several elements (single vs multiple selection, like with grids)
• choose what element we can select (files & folders, files only, folders only)

What do you think?

Currently, only the "Download" option has an icon and this is not consistent:
