EXTJS4.2 控件之Grid 根据数据源某列数据不同绑定不同的控件setEditor

Grid 根据数据源某列数据不同绑定不同的控件，例如：文本框和下拉框

主要代码写在grid的  plugins: [rowEditing],下面这是定义的rowEditing对象，这里面的要定义成 Ext.grid.plugin.CellEditing而不是Ext.grid.plugin.RowEditing

Ext.getCmp(‘pvn‘).setEditor(form组件);这是给grid的列绑定组件，

pvn是在列中定义的id！

如下：

var rowEditing = Ext.create(‘Ext.grid.plugin.CellEditing‘, {// RowEditing

    clicksToEdit: 2,
    listeners: {
        ‘edit‘: function (e, s) {
            var selectedData = grid_DynaProperty.getSelectionModel().getSelection()[0].data;
            if (selectedData.ValueMethod == "1") {
                Ext.getCmp(‘pvn‘).setEditor(
                    new Ext.form.field.ComboBox({
                        name: ‘PropertyValueName‘,
                        typeAhead: true,
                        store: comboData_DynaPropertyValue,
                        valueField: "PropertyValueName",
                        displayField: "PropertyValueName",
                        queryMode: ‘remote‘, //local remote
                        triggerAction: ‘all‘,
                        lazyRender: true,
                        repeatTriggerClick: true,
                        listeners: {
                            "expand": function (combo, store, index) {
                                var selectedData = grid_DynaProperty.getSelectionModel().getSelection()[0].data;
                                comboData_DynaPropertyValue.load({
                                    params: {
                                        PropertyId: selectedData.PropId,
                                        start: startDynaProperty,
                                        limit: limitDynaProperty
                                    }
                                });
                            }
                        }
                    }));
            } else {
                Ext.getCmp(‘pvn‘).setEditor(new Ext.form.field.Text());
            }
        }
    }
});

如图：1.绑定下拉框

2.绑定文本框

代码如下：

var rowEditing = Ext.create(‘Ext.grid.plugin.CellEditing‘, {// RowEditing
    clicksToEdit: 2,
    listeners: {
        ‘edit‘: function (e, s) {
            var selectedData = grid_DynaProperty.getSelectionModel().getSelection()[0].data;
            if (selectedData.ValueMethod == "1") {
                Ext.getCmp(‘pvn‘).setEditor(
                    new Ext.form.field.ComboBox({
                        name: ‘PropertyValueName‘,
                        typeAhead: true,
                        store: comboData_DynaPropertyValue,
                        valueField: "PropertyValueName",
                        displayField: "PropertyValueName",
                        queryMode: ‘remote‘, //local remote
                        triggerAction: ‘all‘,
                        lazyRender: true,
                        repeatTriggerClick: true,
                        listeners: {
                            "expand": function (combo, store, index) {
                                var selectedData = grid_DynaProperty.getSelectionModel().getSelection()[0].data;
                                comboData_DynaPropertyValue.load({
                                    params: {
                                        PropertyId: selectedData.PropId,
                                        start: startDynaProperty,
                                        limit: limitDynaProperty
                                    }
                                });
                            }
                        }
                    }));
            } else {
                Ext.getCmp(‘pvn‘).setEditor(new Ext.form.field.Text());
            }
        }
    }
});
