Dotnetnuke module developers have a lot of tools at their disposal that allow us to have a consistent and familiar user interface among all modules regardless of who made them.  These tools are referred to as controls and one such common control is the file uploader.

Here are some examples of the file uploader control and where you you may see them.

As seen in the Text Editor Link dialog

Uploading a file takes a few steps and when you think you are done, you may not be.

In the first step, you choose that you want to upload a new file by clicking on the Upload New File link.

Once you click on that link, the page will refresh and the control will take on a different look:

Now you need to click on the Browse button and choose the file from your hard drive.

IMPORTANT! Now you need to press the link Upload Selected File Link

Once you press the Upload Selected File link, there will be a delay while the file uploads.  If you are trying to upload a large file, you may get a page error.  Be reasonable with file sizes, this control is not designed for large files.  I would recommend that you never upload a file larger than 5-MB using this tool.

Your file is now uploaded and it is automatically selected.  But you are still not done!

You have uploaded your image, it is selected in the File Upload control, but you have to commit your changes just as you do with any change you make.  This part of the process is module specific and may not appear as you see below.

That is all, if you have a problem, email me or call me.
