Multiple Attachment Custom Control in Sharepoint. Hey guys, sorry for not writing this part within the same period Ive written the previous 3 parts, but that is because I wanted to be sure that the code is written without bugs, so in the previous 3 weeks we have tested the control extensively and solved many issues we have found in it and now its stable, so finally we have decided to post the code to continue our 4 part series of articles. We will now explain the most important part of our Multiple upload attachment control implementation, which is the class that implements all the logic of our control. Remember The control we are going to make is a control that adds multiple attachments to each of 3 lists regarding the type of the file you are going to upload. The three types of files we have are Images, Videos and other files or PDF. So after uploading any file there is a GUID id generated as an id for the file that is saved with the same list as a name for the file uploaded and as a title for the file, the title column will contain the file name and the GUIDs of all the items that contains this file. I know that this article may be somehow unclear but I think some photos will make everything more obvious.

Hi, I have a SharePoint library with one metadata property Project Manager of Person or Group type and I have created a web application to Check In. In the next image is the back end of our control, this is how to create a new column of the type of our Uploader. Here you will specify the 3 lists to be uploaded of your files, these lists are preferred to be on the root of your application and then you will specify the number of files you want to upload per each type, if you want to disable uploading images for example then just make the number of image files 0 and by that you can put Images list name any string as null.
