What is the difference between itemdblclick and rowdblclick? Both of these methods seem to work well for gridpanel. Which is preferable for getting data from a row?
As you mention itemdblclick this seems to be the classic framework.
itemdblclick ( grid, record, item, index, e, eOpts )
rowdblclick ( grid, record, element, rowIndex, e, eOpts )
itemdblclick and rowdblclick are fired from different sources, but otherwise both are equally good to use. For both you receive the record, which holds the data and you receive an index, if you need it.
For me it is more about, what you want to tell another programmer, what you are listening for. And that's where you can differ between cell and row.
The record will be the same for both.
