Good afternoon,

I have a FileManager that I want to perform server-side checks when directories or files are renamed or deleted. For instance, the directory has files that must be kept.

I was hoping to use the command event:

command - API Reference - Kendo UI FileManager - Kendo UI for jQuery

Which mentions:

  • Fired when server command is executed (copy, move, delete or rename).
  • The event is useful to get feedback when server commands has failed or succeeded and take additional actions based on the status.

How, in my delete or update server methods, do I force an e.status of fail, and e.response text explaining why the delete or update was rejected, so I can handle that in the client Command event?

I can see that I could throw an error and then capture that in the Error event, but is it possible to do similar with the Command event?  The scenario I'm describing isn't really an error, just some validation that failed.

Kind regards,

Richard

We have a custom command in a UI for ASP.NET Core FileManager control that states the icon as a simple textual name which worked fine in 2023.1.117


items.Add("").Type("button").Name("refresh").Icon("reload").Text("Refresh").Click("onRefresh").HtmlAttributes(new { style = "margin-left: 5px;" });
After upgrading to 2023.2.606 the icon no longer shows so am curious how the icon should now be referenced.  I've tried using k-svg style class names but to no avail and even using SpriteCssClass with FontAwesome classes is not working.  Could the Custom Command demo for the FileManager be tweaked to show a custom command with a custom icon in the manner that is required for the new SASS + FontIcon + SvgIcon based builds of UI for ASP.NET Core.

I have a request to add SharePoint document management to an existing ASP .NET Core web application and since the project already has Telerik UI in it I'd like to use the File Manager component. I can't find any samples or guidance on how I would attempt to achieve this. Is it even possible?

Everything else within the control works, however the list view and icon view switching buttons do not. Upon clicking the list or icon view buttons as below, the error message at the bottom appears, and I have located no reason why this is the case.

 

kendo.all.js:313050  Uncaught Error: There is no  ViewComponent registered!

Is there a way to configure the FileManager so it displays files in the grid view only? I do see how to remove the option to switch between views but if I use that it only displays files in the list view.

So, basically I do not want clients to have the options to delete or rename files which they have by default when you use FileManager through tag helper. All I need is clients to be able to view available files and download them. Is there any alternative to FileManager to achieve this feature? I greatly appreciate any help or directions. Thank you.

Edit: Using <Context-Menu> tag helper inside the filemanager component accomplished what I was looking for.
