Currently, the FileManager Grid has 3 columns -  Name, Date Created, and File Size. I would like to be able to customize them, i.e. add/remove columns

Greetings.

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, the built-in PreviewPane of the FileManager cannot be modified to include additional information such as new fields or formatting.

When the user renames a folder, the TreeView foes not refresh to display the new folder name.

The test page below is based on the FileManager Events example.

A possible workaround is to recreate the FileManager in the OnUpdate handler:

@using System.IO

@if (ShouldRenderFileManager)
{
    <TelerikFileManager @ref="@FileManagerRef"
                        Data="@Files"
                        @bind-Path="@DirectoryPath"
                        View="@CurrentView"
                        ViewChanged="@OnViewChanged"
                        Height="400px"
                        OnCreate="@OnCreateHandler"
                        OnUpdate="@OnUpdateHandler"
                        OnDelete="@OnDeleteHandler"

The need to right-click a file to be able to download it is a bit less intuitive.

I would like to be able to download a file by double-clicking it, or, more generic, to be able to add a double click handler so I can decide what to do with it.

Greetings.

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.

If the FileManager is nested inside an EditForm or a TelerikForm, it will trigger exceptions. Some of the nested components in the FileManager will require a ValueExpression, as if they are related to the form's EditContext.

When the FileManager is placed in a Window/Dialog, the ContextMenu does not open.

ADMIN EDIT

---

Essentially, the ContextMenu is rendered but appears behind the Window/Dialog and thus it is not visible. The issue is z-index related and a possible workaround is to increase the z-index of the ContextMenu to ensure it will be visible.

Hello,

Nice work on the FileManager component, this will be incredibly useful. I would like to use this control in an Open File Dialog and the only thing I'm missing to support that is what is the selected item in the listview. If I could bind that selection then I could enable/disable my Ok button and provide the selected item(s) when the user hit's ok. Is there a way to access this information?

Thanks,

-Andy
