Hello Ivy,
In certain cases the fileinputs and Select/Browse button
do not show up at all in IE6, 7 and 8 versions.
In fact the issue is a bug in IE6, 7 and 8 where the opacity filter is implemented as an ActiveX
control and it gets buggy in case there are more strict security rules applied.
The above issue can be resolved either by setting the EnableFileInputSkinning property of the RadAsyncUpload to false or applying the following CSS.
CSS:
Thanks,
Shinu.
