copied!<p><strong>Solution for Ext4:</strong></p> <p>I was looking for a solution for this and this guy said the property grid has this behavior. I have adapted it to work in a clean way for me on initComponent I declared:</p> <pre><code>this.editors = { 'date' : Ext.create('Ext.grid.CellEditor', { field: Ext.create('Ext.form.field.Date', {selectOnFocus: true})}), 'string' : Ext.create('Ext.grid.CellEditor', { field: Ext.create('Ext.form.field.Text', {selectOnFocus: true})}), 'number' : Ext.create('Ext.grid.CellEditor', { field: Ext.create('Ext.form.field.Number', {selectOnFocus: true})}), 'int' : Ext.create('Ext.grid.CellEditor', { field: Ext.create('Ext.form.field.Number', {selectOnFocus: true})}), 'boolean' : Ext.create('Ext.grid.CellEditor', { field: Ext.create('Ext.form.field.ComboBox', { editable: false, store: [[ true, 'Sim' ], [false, 'Não' ]] })}) }; </code></pre> <p>I used these functions to help me (copied):</p> <pre><code>this.renderCell = function(val, meta, rec) { var result = val; if (Ext.isDate(val)) { result = me.renderDate(val); } else if (Ext.isBoolean(val)) { result = me.renderBool(val); } return Ext.util.Format.htmlEncode(result); }; this.getCellEditor = function(record, column) { return this.editors[record.get('type')]; }; </code></pre> <p>And finally, associate these functions to the column:</p> <pre><code>{text: "Valor", name : 'colunaValor', width: 75, sortable: true, dataIndex: 'valor', width:200, renderer: Ext.Function.bind(this.renderCell, this), getEditor: Ext.Function.bind(this.getCellEditor, this) } </code></pre>
