Hello,
Is there a way to specify the location to which to save the file to programmatically? Our app. saves to a different folder location depending on the client who is logged in.
Also, is there a way to set whether or not to overwrite existing files on a per request basis? I would like for the user to be able to select a checkbox to decide whether or not they want to overwrite the file, if it exists.
Both of these are currently set in web.config, so just wondering if there's another way?
Thx.

You can use a custom FileNameGenerator to accomplish both of these. Take a look at the FileNameGenerator sample to see the framework. Basically, the logic you define in your filename generator will be called for each file that is uploaded. That way you can put files in different folders based on logged in user.
For the user preference on overwriting, it is similar. Set the existingAction mode to overwrite. Then, in your filename generator, check to see if the file exists and overwrite is off. If so, supply a different filename (perhaps appending a [1] to the filename as browsers do) to supply a new filename.
One thing to keep in mind as you do this is that you will not be able to read other non-file form elements when your file name generator is called. This is because browsers send up forms with files and other elements intermixed, so there is no guarantee of element order. All elements are read sequentially. So the checkbox will have to be done in a user preference dialog or a different wizard step. Or perhaps an ajax call. If you don't want to opt for an extra step, another option would be to use the Guid file naming method, and then perform the logic and move the files in the UploadManager's UploadComplete event. At that point, all form elements will be available, so you can read the checkbox value.
Let me know if you have additional questions regarding this.

If we have: existingAction="Rename", and I use the following code to retrieve the filename:
for (int i = 0; i
{
it.MoveNext();
Krystalware.SlickUpload.UploadedFile fr = (Krystalware.SlickUpload.UploadedFile)it.Current;
string f = fr.ClientName;
}
The problem is that when a file with the same name exists it saves the file on disk appending to it '[1]' or [2].... (which is desired) but the filename that is fetched does not have the appended information with it. Is there an easier way than fetching all the files and checking whether the filename is there, and them checking whether the filename[1] is there... and then adding the [ n ] to it?
Thanks.

Sure... Index into the LocationInfo dictionary to get the server file name:
string path = file.LocationInfo[FileUploadStreamProvider.FileNameKey];
For answers to this and other questions, check out the SlickUpload FAQ.

When doing the rename option, when there are no files in a directory, and we upload file: x.txt, the uploaded file shows up as: x[1].txt.
Is there a way to not append anything to a file when its the first file of that name in that directory.
Thanks in advance.
