New File Indicator

[Vinh]

Hi, I'm looking an either client-side or server-side to either append '*' to the Folder Name or switch the icon.  Right now, we're only allowing members to download the files and we keep that the download status.

Thanks

Hi Vinh,

I already answered your support ticket on the subject. For convenience I will paste my answer here as well.

If I understand you correctly, you need to mark the newly uploaded files with a marker in the file list. RadFileExplorer does not offer such functionality out-of-the-box. Nevertheless, to achieve this I would suggest you to sub-class the FileSystemContentProvider class and override its StoreFile() and ResolveDirectory() methods.

1. In the StoreFile() method save information of the uploaded file(for example in a database) to mark it as latest upload.
2. In the ResolveDirectory() check if any of the files is marked as latest upload, and if so add a custom attribute to it (as demonstrated in this live demo).
3. Handle the RadFileExplorer's ClientFolderLoaded client-side event and change the icon of the grid's row, e.g.:
   

   function OnClientFolderLoaded(oExplorer, args)
   {
       var dataItems = oExplorer.get_grid().get_masterTableView().get_dataItems();
   
       for (var i = 0; i < dataItems.length; i++) {
           //get reference to the data item
           var item = dataItems[i];
   
           //get the value of the "CustomAttribute"
           var itemCustomAttribute = item.get_dataItem().Attributes["CustomAttribute"];
   
           if (itemCustomAttribute == "CustomAttributeValue") {
               //change the background image
               $telerik.$("td:first-child", item.get_element()).css("background-image", "url('latestUploadIcon.gif')");
           }
       }
   }
