[Ibrahimp]

hi,
how do i validate my property values before submitting in Ext.grid.property.Grid? below is my grid and store.


propsGrid = Ext.create('Ext.grid.property.Grid', {
id: 'propsGrid',
width: 300,
source: source
});


var propertyStore = Ext.create('Ext.data.Store', {
autoLoad: true, //autoload the data
proxy: {
type: 'ajax',
url: 'ScriptParameter.aspx'
},
fields: ['key', 'value'],
listeners: {
load: {
fn: function (store, records, options) {
// get the property grid component
var propGrid = Ext.getCmp('propsGrid');
// make sure the property grid exists
if (propGrid) {
store.each(function (record) {
source[record.get('key')] = record.get('value');
});
propGrid.setSource(source);

}
}
}
}
});

please suggest.

Thanks

Fires after editing, but before the value is set in the record. Return false from event handler to cancel the change.

Have you reviewed the validateedit event?
