ListGrid Row Selection

[apvanderveen]

Hi,

I have a ListGrid bound to a RestDataSource. I am trying to figure out how to advance the grid to a specific row programmatically.

For example, I may have 5000 rows in the datasource and only the first 50 are displayed. I would then like to be able click a button and advance to row 3422. I can capture the click event but I am having trouble figuring out how to select row 3422.

Thanks,
Arend

Hi,

I made some progress on this. The following code will select 21st (zero index) record.

addDataArrivedHandler(new DataArrivedHandler() {

	public void onDataArrived(DataArrivedEvent event) {
		// TODO Auto-generated method stub
		selectRecord(20);
	}
});

However, if I changed it to selectRecord(3422), nothing happens. My data source only loads 50 records at a time.

Thanks,
Arend

If I am not mistaken when you click your button, you will have to do a fetch passing in startRow, endRow of 3400 and 3450 and then in your dataArrived event select record 21

Thanks for the reply.

I finally found a nice little function called scrollToRow()

DeferredCommand.addCommand(new Command() {
	public void execute() {
		scrollToRow(3433);
	}
});

That did the trick.

Thank,
Arend
