Hi Ranjinikg,
1. Method "UploadProgressChanged" is not a part of DotNetGallery, if it is your own method, I think you need to check your code which fire this method.
2. And the progressbar, do you mean the progressbar of the DotNetGallery upload function? DotNetGallery does not provided the method to custom the progressbar image. So I am not sure what is the "frmTimer1.ProgressBar1.Value" mean.
Can you explain your question in detail?
Regards,
Ken
