View Full Version : Re-rendering individual grid cell

28 Jan 2010, 4:51 PM

I have a Live Grid with many columns and a separate editing panel for the grid's fields.

I am successfully updating the grid's store with the model data from the edit panel, however I would like to re-render only the affected row in the grid and cannot determine how.

The Javadocs for Store indicate that the grid is automatically updated, however my code below doesn't appear to:

I resorted to the rather nasty code to re-render the grid:

grid.getStore().fireEvent(ListStore.DataChanged, new StoreEvent<ItemGridModel>(grid.getStore()));however this resets the grid's horizontal scrolling. The grid has around 30 columns so this is not ideal. Ideally, I'd like for the user to be able to scroll to a position in the grid, edit the fields for the selected row, hit save and for the grid to not move.

Is there a simple re-render row event that can be fired? I've dug through the editable grid code in GXT for the closest equivalent and can't see anything obvious. I could try View.focusCell() but I suspect this will still make the grid jump.

Any pointers would be appreciated.

Apologies, just realised I posted this in the wrong forum. Will re-post in the GXT forum.
