Trigger Expand or Collapse in TreeByNestingTableColumn

[Former Member]

Hello all,

Can I trigger expand or collapse in TreeByNestingTableColumn by myself?

We need that the table will be visible by default, thus all leaves expanded.

Thanks,

Hi Haguy,

You can create a attribute and bind it to expanded property of Tree by nesting

true -> expanded

false-> collapsed

Hi Ayyapparaj,

I tried to change the Expanded value in run-time.

It did change the arrow head icon to "Expanded" but all the data under the branch was hidden. When I pressed the icon twice, one time to collapse it, and another to expand it, the data appeared.

Perhaps the only way to expand the tree correctly is by the user "Expand" event that I cannot capture.

Best Regards,

Hi Abhijith,

I know this tutorial already, I followed it to create my tree.

The first thead is related to the size of the table, not to the status of the leaves.

The second thread is on htmlb, I hope to solve the problem still using Web Dynpro.

But, thanks anyway!
