Annoying scroll bar in web dynpro

[Former Member]

When scrolling in tables this is very annoying that we cant see the actual rows till we release the mouse.. is there any way to fix this beside giving "-1" in the "RowCount" property because when using trees for example the table jumps to the first row when expending a node. and its not very user friendly when the screen size is changing according the the row count when using trees....

Hi Bar,

For better performance, Web Dynpro uses server-side scrolling in tables. The new table rows aren't loaded until the user releases the scroll bar button and triggers a round trip to the server to fetch the new rows.

You can control the text that is displayed using the Table's SCROLL_TIP_PROVIDER aggregation, so instead of reading "Row 24 - 33 of 49" you could have it read something more informative. See the information on TableScrollTipProvider.

If it's really a problem, one option could be to revert to a paginator instead of the scroll bar. See information on the WDTABLENAVIGATION application parameter.

Cheers,

Amy

Hi Amy!

I am unable to get paginators although I have assigned Paginator to the application parameter .

Can you just xplain me the exact steps for the same...

Thanks!

Ah, sorry Krishna, I found this bit of information in the Table documentation which explains that, as of NW 7.01, when Lightspeed rendering is enabled, the paginator setting is ignored and only the scrollbar is available.

When the WDLIGHTSPEED parameter is activated in accessibility mode, paginators are not used any more. The corresponding application parameters for the paginator and accessibility mode are ignored.

In accessibility mode you can navigate in the table using the cursor keys. 

See also OSS note 1107662 - Web Dynpro ABAP: Unified rendering light speed (7.01, 7.11).

I wouldn't recommend disabling Lightspeed in order to get the paginator back because that will cause performance issues in your applications. I'm afraid you are stuck with the scrollbar and its lazy-loading "feature".
