Hi,

I am using longpolling to Push updated data into a fixgrid in my frontend.
When updating Data in the fixgrid (either changing elements or adding/deleting some), I make sure that the item is sorted into the grid by simply calling
Code:

fixgridListBinding.resort()

Unfortunately, this causes two problems:

Focus is lost.

Selection is lost.

The loss of the selection is no problem, I just need to grab the selectedItems before the resort and then reselect these items.

More interesting is the loss of the Focus. I have meanwhile tried ensureItemToBeDisplayed, but that results on the item being always focussed as the top row of the displayed rows (so if I select a line in the middle then the item and the focus "jumps up").

Does there exist any way to preserve and restore the vertical scroll position of a fixgrid?

Cheers,

Björn

Hi,

yes there is a way:

You receive the current horizontal scroll position by

FIXGRIDBinding.getCurrentHorizontalScrollPosition()

any you can set by

FIXGRIDBinding.scrollHorizontallyToPosition(int value)

Hi,

unfortunately, this is the horizontal scroll position.
I need the vertical scroll position.
But yes, if there were something like get/setVerticalScrollPosition, that wourd be exactly what I need.

Cheers,

...the vertical scroll position is set by setting setSbvalue(...) - the index of the current top-line of the grid.

Please also check method ensureToBeDisplayed(...) with FIXGRIDBinding.

Regards, Björn

Thanks. This does exactly what I want.
I should have known this ...
