For implementing a file browser you better use a TreeByNestingTableColumn as master column of the table which gives you a hierarchical table structure.

For displaying folders as links and files as non-clickable links you can either

- use table cell variants with LinkToAction and TextView as cell editors or

- just disable the link for the file rows and use type=WDLinkType.RESULT.

Example:

Context
+ Rows (table data source node)
  + dirEntry: File
  + linkEnabled (boolean, calculated=true)
  + linkType (LinkType, calculated=true)

Bind the "enabled" property of the LinkToAction to attribute "linkEnabled" and the "type" property to "linkType". Implement the calculated attributes like

boolean getRowsLinkEnabled(IRowsElement element)
{
  return element.getDirEntry().isDirectory();
}

WDLinkType getRowsLinkType(IRowsElement element)
{
  return element.getDirEntry().isDirectory() ? WDLinkType.NAVIGATION : WDLinkType.RESULT;
}

But as mentioned, I would prefer using TreeByNestingTableColumn or table cell variants.

Hi,

By using [cell variants|http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/c0310fd2-f40d-2a10-b288-bcbe0810a961?quicklink=index&overridelayout=true] its possible.

Hi,

as I said, in this case, you will have to change the UI element programatically. How to do this, you can read in the following links:

Or you can search youself SDN for dynamic handling of UI Elements.

Hi,

try not to disable the link. a disabled link is still visible. try the propery "visibility". there you can set visible, blank, or none. set blank or none if the resource != collection. so nothing will be displayed, if it is a file.

if you want he files not to appear as links, but as text, you have to change the UI element. then you should use TextView or Label.

Best regards,
