How do you change the files of type available upon clicking the Browse button in the FileUploader.ascx dialog? I only want to limit it with the file extensions allowed to be uploaded. I hope you can help me out here.
I am not quite sure whether you want to customize the "browse" or the "upload" dialogs, so I have attached screenshots of both dialogs.
If you want to restrict the types of the files that can be uploaded, you can do that by setting the SearchPatterns property :
<telerik:radeditorrunat="server"ID="RadEditor1">
<ImageManager
UploadPaths="~/images"
ViewPaths="~/images"
DeletePaths="~/images"
SearchPatterns="*.gif,*.png"/>
</telerik:radeditor>
If you want to change the file types that can be viewed in the "browse" dialog, however, this is not possible because it is a standard MS Windows dialog.
