Select row after ScrollToRow

Hi!
Thank you very much for your excellent grid!!!
I have a problem: I can't select row after scroller().scrollToRow.. (server-side)

I have found a similar question, but there is no decision there:(
Help plz!

The previous discussion does have a solution using the draw event. The trick is figuring out how you are going to track the row to select. I put together this example based on the Server-side processing (5,000,000 rows) example:
http://live.datatables.net/nivizera/1/edit

Its a brute force example that tracks the row (either '0' or '5000'). Click the "Goto 5000" button and row 5000 will be shown and highlighted.

In the table.on( 'draw', function () {...}) function you will need to determine if you want to select the row each time the table is drawn. In the example I only select the row if the "Goto" button is clicked. You will also need to decide how to determine which row to highlight. I simply use a function to return the row that has 5000-1 in column 0. Your case will be different using the row() selector and modifier parameters.

Hi nightop,

The problem is that the draw only occurs when the data is loaded, the little nudge between 5000 and 5002 won't cause a redraw since it's within the buffering window.

There doesn't appear to be a scroll event that you could listen for - there's been some chat on it, but I don't believe it's been implemented yet.

Take a look at this thread from @squaregoldfish, he appeared to have the same problem and found a fix, though it looks more like a workaround than a solution.

Hope that helps,

Cheers,

Colin
