SharePoint-use the upload attachment control in a custom form

Problem description:

I added a webpart to the custom form CNewForm. aspx, but when creating an Item, click "Attach File". The system prompts

This form was customized not working with attachement.

I used IE Developer debugging to find clues in the UploadAttachment method in Form. js: some elements are not defined.

Later, according to Microsoft's official Article http://support.microsoft.com/kb/953271/en-us, after modification, the values of the inventory attachment and fieldsare normal.

However, an error occurred while executing The SaveButton. SaveItem method: SPException: The list item was saved, but one or more attachments cocould not be saved. <br> cocould not upload file.

Solution:

Code for deleting this row: <SharePoint: FormComponent ID = "FormComponent1" TemplateName = "AttachmentRows" runat = "server"/>
