Disabling row in table control

Posted on Aug 02, 2006 at 11:24 AM 95 Views

Hi All,

We are developing an application in Webdynpro using java.

Can we disable or enable a row selection on certain condition in Table Control and if yes How?

Thanks & Regards,

Nilesh

    Hi Nilesh

    This has been already discussed. See the forum link. It works fine.

    Nilesh,

    There is no way to disable <b>selection</b> of particular row(s). It is possible only to disable selection alltogether for whole table. Or to disable cell editors (as other suggesting).

      Having a look at this code, I recall that NW04s (probably latest NW04 SPs like SP16) has selectionChangeBehavior property on Table control.

      If you are using version that supports this property, you may do the following:

      1. Set selectionChangeBehavior=manual. This way row is not selected automatically.

      2. Add onLeadSelect action to table

      3. Create mapping of "nodeElement" parameter to parameter "row" of type IWDNodeElement

      4. In action handler check row.index(). If index is selectable, then execute wdContext.node<TableSource>().setLeadSelection( row.index() ) otherwise return.

      This way user will be unable to select certain rows. This works only with single selection (not multiple).

      Up to certain extent you may try the same even without selectionChangeBehavior property. Just always save lead selection to controller instance variable and try to restore previous selection in onLeadSelect action handler.
