I am new to EXTJS. I have grid with a checkbox, and the checkbox will be checked or unchecked based on the boolean field in the model. I have this listener which does that when the store is loaded .Here is the following code.
listeners: {
afterrender: function(obj)
{
var store = THIS.GridStore;
var model = THIS.GridView.selModel;
model.suspendEvents();
store.load(
{
scope : this,
params : {
method : 'getData',
eventId : 'nativemethodcall',
subEventId : ''
},
callback: function(records, operation, success)
{
model.suspendEvents();
var count = store.getTotalCount();
for (var i = 0; i < count; i++) {
var record = store.getAt(i);
if(record != undefined)
{
if (record.get('analyticsEnabled') == true) {
model.selectRange(i, i, true);
}
}
}
model.resumeEvents();
}
});
}
}
After the UI is rendered , I have listeners in checkbox selection model which will be called when the user checks or unchecks the checkbox and updates the model respectively. Code
selModel : Ext.create('Ext.selection.CheckboxModel',
{
listeners :
{
deselect: function(model, record, index)
alert('deselect called');
{
var store = THIS. GridStore;
var record = store.getAt(index);
record.set("Enabled", false);
THIS.GridView.refresh();
},
select: function(model, record, index)
{
alert('select called');
var store = THIS. GridStore;
var record = store.getAt(index);
record.set("Enabled", true);
THIS.GridView.refresh();
},
selectionchange: function(model, selected, eOpts)
{
alert('selection called');
var count = THIS. Store.getTotalCount();
var selcount = selected.length;
if (selcount == 0)
{
model.deselectAll(true);
var store = THIS. GridStore;
var count = store.getTotalCount();
for (var i = 0; i < count; i++) {
var record = store.getAt(i);
if (record.get('Enabled') == true)
{
record.set("Enabled", false);
}
}
THIS.GridView.refresh();
} else if (selcount == count)
{
model.selectAll(true);
var store = THIS. GridStore;
var count = store.getTotalCount();
for (var i = 0; i < count; i++)
{
var record = store.getAt(i);
if (record.get('Enabled') == false)
{
record.set("Enabled", true);
}
}
THIS. GridView.refresh();
}
}
}
}),
The problem I am facing is that, the selection checkbox model listeners(select & selection change ) function gets called when the call back functions checks the checkbox during the store load . I have suspended the model event like this var model = THIS.GridView.selModel; model.suspendEvents(); during the call back, but it doesn't seems to work .Please help.
