Thank you for your interest in the RadUpload
The upload control provide some basic filters right of the box - MaxFileCount
. If you need some more sophisticated filter then you should rely on the FileSelected
event - here you can access the FileInfo
structure for all the selected files. In the attached example we are filtering against the minimum size of 4kB.
Please give it a try and let us know if there are more questions.
