Thumbnails not refreshing

[Ignacy Mielniczek]

Hi Syncfusion,

We are using yours FileManager components in the project and one of our tester found a behavior that we would like to fix. It is not refreshing thumbnail for images files.

Case:

1. Upload 2 different image, for example:

- image_1.png,

- image_2.png

2. Rename image_1.png to let say image_3.png.

3. Rename image_2.png to image_1.png.

After this operations you should end up with 2 different files having the same thumbnail.

Like we did here [those are different files]:

And below you have console view for them:

How to fix it?

Kind regards,

Hi Frank, 

Greetings from Syncfusion support. 

Based on your query, we suspect that you are facing a thumbnail issue while renaming the image files(.png extension) in File Manager component. So, we have prepared a File Manager sample and renamed the image files but unfortunately we are unable to reproduce it at our end as the thumbnails of image files are refreshed properly in File Manager.    

We have attached our validated sample for your reference.
