I managed to get a little further. I am now able to select the column from the list and specify the document library. After i select my document, i press Upload button i get an error. So i modified the Button_Click event as follows ;

String siteURL = SPContext.Current.Web.Url;
string error_string = “”;

try
{
using (SPSite sourceSite = new SPSite(siteURL))
{
error_string = “SPSite ” + sourceSite.Url;
using (SPWeb sourceWeb = sourceSite.OpenWeb())
{
error_string = “SPWeb ” + sourceWeb.Url;
sourceWeb.AllowUnsafeUpdates = true;
FileUploadCustomField _field = (FileUploadCustomField)this.Field;
error_string = “_field.UploadDocumentLibrary ” + _field.UploadDocumentLibrary;
SPList objList = sourceWeb.Lists[_field.UploadDocumentLibrary];
error_string = “SPList ” + objList.Title;
SPFolder destFolder = objList.RootFolder;

if (UploadFileControl.PostedFile == null) return;
string strFileName = UploadFileControl.PostedFile.FileName.Substring(UploadFileControl.PostedFile.FileName.LastIndexOf(“\\”) + 1);
error_string = strFileName;
Stream fStream = UploadFileControl.PostedFile.InputStream;

SPFile objFile = destFolder.Files.Add(strFileName, fStream, true);
objFile.Item.UpdateOverwriteVersion();

StatusLabel.Text = “Upload File :: Success View (” + “/” + objFile.ParentFolder + “/” + strFileName + “)“;
hdnFileName.Value = “/” + objFile.ParentFolder + “/” + strFileName;
sourceWeb.Dispose();
}
}
}
catch (Exception ex)
{
StatusLabel.Text = “Upload File ” + error_string + ” :: Failed ” + ex.Message + ” ” + ex.StackTrace;
}

error_string captures the value of objects as the code is exectued.

The error returned to sharepoint is as follows.

Upload File _field.UploadDocumentLibrary :: Failed List ” does not exist at site with URL ‘http://mysharepointsite:40861/ims/QMS’. at Microsoft.SharePoint.SPListCollection.GetListByName(String strListName, Boolean bThrowException) at SharePoint2010.Controls.FieldUploadCustomFieldControl.UploadButton_Click(Object sender, EventArgs e)

So it seems for some reason UploadDocumentLibrary is being returned as ” “.

An ideas why? Where could i start looking inorder to debug the error?

Unfortunately i cannot upload the solution as-is. That’s the reason why i have inserted the code. It’s almost the same. Can you tell me the errors that you are having. I would be able to reply to that.

I know this is a slightly old thread, but i would like to use this custom field in a project, but i am getting syntax errors? It seems you are the only one who managed to get it to work? Can you send me your working project please??

I have to hand it to you, this is a very good solution! Is there any chance you could upload the actual project its self?

Would really appreciate it.

Thanks.

I think your code are missing some lines, for example, in the “FileUploadCustomField.cs”, on the ‘FieldRenderingControl’, your new FileUploadCustomField() doesn’t input the arguments as required by the 2 constructors that you have included in this example.

Or point me out if I’m wrong here.

You will need to reference the System.Web in your Visual Studio before importing into the code.
