remember after refresh selected row in extjs grid

Question

I have a problem. I use extjs grid. This grid will be refreshed every seconds.

I refresh with this function:

ND.refresh =          


        

Answer 1

Here is another way to select the previously selected record:

var selectionModel = grid.getSelectionModel()

// get the selected record
var selectedRecord = selectionModel.getSelection()[0]

// get the index of the selected record
var selectedIdx = grid.store.indexOfId(selectedRecord.data.id);

// select by index
grid.getSelectionModel().select(selectedIdx);

For some reason the grid.getSelectionModel().select(record) method wasn't working for me, but selecting by index seems to work.

Edit: found out why grid.getSelectionModel().select(record) method wasn't working. Apparently the store is reloaded, the record instances aren't the same (they have different automatically generated Ext IDs). You have to use selectAt() in this case.
