Auto scroll to top of page/application

[Former Member]

Hello all,

I'm taking my first steps with Web Dynpro and I've come up against a bit of a problem.

I have a view (on the left of a TLayout90 ViewSet) which contains a Tree object. When a leaf node of the tree is selected I display some related data, in a table, on the top right of the ViewSet.

My problem is that the tree grows quite large and can cause scroll bars on the page; meaning that when the View on the top right is displayed it can be off of the screen to the top. If I open many nodes, forcing myself to scroll down the screen before selecting a leaf node then the View on the top right appears and works fine but I have to scroll back up the page to see it.

Is there any way of forcing the page back to the top after a leaf node is selected so that the resulting table (in the View on the top right of the ViewSet) can be seen?

I don't want to have to write this again from the start as two applications and therefore two iViews on the page with a Tree iView using an event to send the code of the selected TreeNode into the Table iView for display.

Thanks in advance,

Patrick.

Hello Patrick,

I would suggest you to use ScrollContainer with ViewContainerUIElement inside instead of viewset.

Thanks Maksim,

I'll have a look into that tomorrow from the office.

The quick fix that I'd thrown on was to request focus to an InputField that I have at the top of the screen, that pulled the page up. It's obviously more of a fix than a solution though.

I'll have a look at the ScrollContainer and ViewContainerUIElement tomorrow and let you know how it goes.

Thanks again,

Patrick.

Hi again Maksim,

I've tried using the layout that you suggested but I still get the scroll bars adding themselves to the page and not to the TreeView itself.

Do you have any idea what I could be doing wrong?

The idea of adding scrollbars specificaly to the TreeView would be the best solution.

Edit: I see that the height and width parameters are required, now I get scroll bars around the tree.

In the end I didn't use the ViewContainer but simply added the Tree object to the ScrollContainer.

Thanks for your help Maksim.

Patrick.

Hello Patrick,

Put TreeView to ScrollContainer, set height and width properties of ScrollContainer to appropriate values and set scrollingMode to auto.
