问题 how can i get the selected cell of a Ext.grid.Panel? In ExtJS 3 it was possible via: grid.getSelectionModel().getSelectedCell() In Ext 4 there is grid.getSelectionModel().selected but this only gives me the record. 回答1: There may be a more direct way to do this but the following seems to work for me: grid.view.getCellByPosition(grid.getSelectionModel().getCurrentPosition()); 回答2: I ended up needing the actual column that the user was clicking on and discovered the following: grid.panel

问题 Instead of retrieving a single row of data from my store, how can I modify the following code to retrieve all records? var store = Ext.data.StoreManager.lookup('MyStore'); store.setProxy({ type: 'pagingmemory', data: store.getAt(0) }); store.load(); Any thoughts? 回答1: You can use store.getRange() or you can use store.data.items .

I would like to make the total height of the accordion the height of the headers plus the height of one panel body (expanded).

问题 In an Ext JS grid, I'm editing individual cells. In one of the columns I have a Save button which fires the Save event. How can I remove the dirty flag (in red box in my image below) in the edited cell? I don't know how to perform the create, update and destroy options with the proxy because the documentation have a good example, so I'm planning on doing an AJAX request for these steps until I can take actual Sencha training. However, if the dirty flag resolves itself if I work the store and

问题 I see that panels have the option to set scroll: to horizontal or vertical, but is there any way to do something like: scroll: 'false' ? I've tried such without luck. I have a DataView nested in a Panel. I can set the scroll direction of each independently, but I want the DataView not to scroll at all. [Any tips will earn answer points and a digital high five.
