    <p>i use a livegrid in ExtJs 3.3.1 but believe this question is global to ExtJs. How does a listener on a store know which grid the event comes from ?</p> <p>Here why and some code.</p> <p>I have a listener on a store and on update i would like to know which rows were selected in the grid and also suspend the events. This all so that i can make a selection in the grid, update a field in that range and update that field in the whole selection. Selection is done without a checkbox, just by highlighting the rows. Since this listener is used by many grids i need a way to get it froml what the gridlistener gets as parameters but that is only store, record and action</p> <pre><code>Ext.override(Ext.ux.grid.livegrid.Store, { listeners: { 'update': function(store, record, action) { if (action=='commit'){ //each update has 2 actions, an edit and a commit var selected = grid.getSelectionModel().getSelections(); //need to know which grid if (selected.length&gt;1){ //if more than one row selected grid.suspendEvents(); store.writer.autoSave = false; for(var i=0; i &lt; selected.length; i++){ if (this.fieldChanged) { for (var name in this.fieldChanged) { //get the field changed and update the selection with the value if (selected[i].get(name)!=this.fieldChanged[name]){ selected[i].set(name, this.fieldChanged[name]); } } } } grid.resumeEvents(); store.fireEvent("datachanged", store); store.writer.autoSave = true; } } if (action=='edit'){ this.fieldChanged = record.getChanges() } } } }); </code></pre>

    1. COWhat exactly are you trying to accomplish? Grid should update its stuff automatically. It's not clear from your question what _real_ problem is

    2. COthe problem is, i use this listener for many grids and i need to know in the listener itself which grid it is handling at that moment

    3. COI understood that. What exactly are you trying to do in the listener? Looks like you're manually updating the grid and that should happen automatically

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
