Selecting specific row by row number [message #1397877]

Hi,
I would like to select a certain row by its number. I tried the approach with:

natTable.doCommand(new SelectRowsCommand(natTable, 1, rowNumber, false, false));

But this selects the row from the currently visible rows (so eg. scrolled to row 500 -> select row 2 -> selection is now 502 instead of 2)
Is there any better approach to do this?

A coordinate in NatTable is a combination of layer and position. Your example will create the coordinate for NatTable row position 2. As you have a viewport, the position is related to the current scrolling position.

Try

natTable.doCommand(new SelectRowsCommand(dataLayer, 0, rowNumber, false, false));

which will use a DataLayer coordinate.

If that doesn't work, try

selectionLayer.doCommand(new SelectRowsCommand(selectionLayer, 0, rowNumber, false, false));

Although from my understanding the first one should work.

Thank you. The selectionLayer way works!

Although to the the same issue: I create a DefaultGridLayer and save that as a variable. Then I access the selection layer via gridLayer.getBodyLayer().getSelectionLayer() is that a strange way to do this or is this fine Very Happy
