Hi
Bruno,
Greetings
from Syncfusion Support.
Yes,
this can be achieved using the BeforePopupOpen
event of the FileManager component.
In
the sample we’ve prepared for you:
- In the BeforePopupOpen event handler, we
retrieve the currently selected files/folders using the getSelectedFiles()
method.
- We then check the names of the selected items against
the ones you want to protect from deletion (in this demo, we prevent
deletion of the "Music" folder you can easily customize this
logic to match your specific file/folder names or conditions).
- If the popup type is "delete" and one
of the protected items is selected, we set args.cancel = true to
block the delete action and prevent the confirmation popup from
proceeding.
This
approach gives you full control to block deletion for any specific files or
folders based on your rules.
Here’s
the sample for your reference: https://blazorplayground.syncfusion.com/hDBnZVVJnfaVxCVL
Code
Snippet:
|
<SfFileManager
TValue="FileManagerDirectoryContent"
@ref="fileManager">
<FileManagerEvents TValue="FileManagerDirectoryContent"
BeforePopupOpen="open"></FileManagerEvents>
</SfFileManager>
@code
{
SfFileManager<FileManagerDirectoryContent> fileManager;
private void open(BeforePopupOpenCloseEventArgs args)
{
var selecteditems = fileManager.GetSelectedFiles();
if (selecteditems[0].Name == "Music"
&& args.PopupName=="Delete")
{
args.Cancel = true;
}
}
}

Please
review the sample, test it with your scenario, and let us know if it fully
addresses your requirement.
