problems with RowSelectionModel - Ext JS

SINGLE ROW

var tcs = grid.getSelectionModel().getSelected();

I get this error
this.selections.getAt is not a function

MULTI-ROW

var tcs = grid.getSelectionModel().getSelections();

doesn't produce any javascript errors, but the array it returns isn't an array of row id's.

Here is my grid setup code:

     // preheats grid
      var cm = new Ext.grid.ColumnModel([
         {header: "ThermoCouple", dataIndex: 'tc', width: 89, sortable: true}, 
         {header: "Target Time", dataIndex: 'time', width: 75, sortable: true} 
      ]);
      var record = Ext.data.Record.create([
        {name: 'tc', mapping: 'tc'},
        {name: 'time', mapping: 'time'},
      ]); 
      var reader = new Ext.data.JsonReader({
        root: 'result',
        id: 'tc',
      }, record);        
      ds = new Ext.data.Store({
        proxy: new Ext.data.HttpProxy({url: 'preheat/tc'}),
        reader: reader
      });
      ds.setDefaultSort('tc');
      grid = new Ext.grid.Grid('preheats-grid', {
        ds: ds,
        cm: cm
      });
      grid.addListener('rowdblclick', viewGraph);
      grid.render();

The 2nd is a "documentation hasn't been updated error". It actually returns an array of the full record objects. getSelected should return 1 record object, but getAt should be itemAt. I have fixed both these issues and will be deploying a new zip shortly.

getSelected() returns a MixedCollection. What is the index property in the MixedCollection?

Look at the source for MixedCollection - it's pretty completely documented. You can call item(key), itemAt(index), etc. There's quite a few ways of getting at the data. __________________ Tim Ryan - Ext JS Support Team Read BEFORE posting a question / posting a Bug Use Google to Search - API / Forum API Doc (3.x | 2.x | 1.x) / FAQ / Wiki / Tutorials / 1.x->2.0 Migration Guide

Tim - here is my code: var deleteRow = sm.getSelected(); deleteRow.each(function(key) {alert(key + ' : ' + deleteRow.get(key));}); I receive the error deleteRow.each is not a function. However if I use the line deleteRow.get('title') it pulls my data out fine... Any help is appreciated Aaron

I haven't done much with this yet, but looking at the code, getSelected returns a Record, not a MixedCollection. Get works b/c Record also has a get method. I would suggest stopping in debug after getSelected and looking at what that object actually is. Maybe it contains the data in a MixeCollection?? - try looking at the internal 'data' property. __________________ Tim Ryan - Ext JS Support Team Read BEFORE posting a question / posting a Bug Use Google to Search - API / Forum API Doc (3.x | 2.x | 1.x) / FAQ / Wiki / Tutorials / 1.x->2.0 Migration Guide
