You can then also download the file.

• Here's a look at the implementation method

1. Web pages uploaded by attachments

Create a new normal Web program, plus an ASPX page for file uploads, using the uplodify in jquery:

This is the JS code to implement the upload

  1:  function ()
  2:         {
  3:             uploadfiles ();
  4:         });
  
  6:         function uploadfiles ()
  7:         {
  8:             $ ("#uploadify"). Uploadify ({
  9: '                 swf ': ' scripts/upload/uploadify.swf ',
Ten: '                 uploader ': ' Uploader.ashx ',
One: '                 queueid ': ' Filequeue ',
:                 ' auto ': false,
:                 ' multi ': true,
:                 ' onuploaderror ': function (file, ErrorCode, ErrorMsg, errorstring)
:                 {
:                     ' the file ' + File.name + ' could not being uploaded: ' + errorstring ';
:                 },
:                 ' onuploadsuccess ': function (file, data, response)
:                 {
:                     ' <li><a href= ' + data + ' "> ' + file.name + ' </a></li> '). AppendTo ($ (' ul '));
:                 }
:             });
:         }
:         function Upload ()
:         {
:             ' #uploadify '). Uploadify (' upload ', ' * ');
:         }

This is what is displayed on the page:

  1:   class= "gbtext" >
  2:             <tr>
  3:                 <td>
  4:                    <input type= "file" name= "uploadify" id= "uploadify"/>
  5:                 </td>
  6:                 <td>
 7: <input type=" button  "value=" 
    
     upload Files  "
     class  =" 
     uploadify-button  "style=" 
     height:25px; width:  112px;  " onclick= "
     javascript: $ (' #uploadify '). Uploadify (' upload ', ' * ') "/> 
    
  8:                     <input id= "Yesclass="button"onclick="upfiles ();"onmouseout="  This.classname= ' button '"onmouseover="this.classname= ' button-hover '"style="width:50px" Type= "button" value= "Confirm"/>
  9:                 </td>
Ten:             </tr>
One:             <tr>
:                 <td colspan= "2" >
:                     <ul id= "ul" ></ul>
:                 </td>
:             </tr>
:         </table>
:     <div id= "filequeue" >

Finally put it under the ISV:

2. Attachment Entities

• Field

The fields in the red box are the lookup type, the ID of the entity that needs to implement the upload function, and the rest is the basic field

• Interface

The Middle red box is an IFRAME, and nothing else is introduced:

• Invoke JS file to upload Web page

  var uploadcfg = {
  2:     fileFloder:Xrm.Page.data.entity.getEntityName (),
  3:     entityReferenceName:Xrm.Page.data.entity.getEntityName () + "ID",
  4:     entityName:Xrm.Page.data.entity.getEntityName (). toLowerCase ()
  5:};
  
  function UploadFile () {
  8:     var openURL = "/isv/filesupload/fileupload.aspx?" filefolder="+ Uploadcfg.filefloder +"&entityname="+ uploadcfg.entityname
  9:         + "&entityreferencename=" + uploadcfg.entityreferencename + "&entityid=" + Xrm.Page.data.entity.getId ()
Ten:         + "&userid=" + Xrm.Page.context.getUserId ();
One:     windowshowmodaldialog (OpenURL, "_blank", "dialogwidth=500px;dialogheight=300px; Help:no;status:no");    //Open modal form
12:}

• Upload button

Add a button and specify the function name UploadFile
