## LowLevelSelectAsync(IEnumerable&lt;Int32&gt;, Boolean, Boolean)

Selects some values in a field, by entering the element numbers related to the values to select.

### Declaration

```

          [QixName("LowLevelSelect")]
public Task<bool> LowLevelSelectAsync([QixName("qValues")] IEnumerable<int> values, [QixName("qToggleMode")] bool toggleMode, [QixName("qSoftLock")] bool softLock = false)
    
  
```

### Parameters

| Type | Name | Description |
| --- | --- | --- |
| System.Collections.Generic.IEnumerable&lt;System.Int32&gt; | values | Indexes (or element numbers) of the values to select. |
| System.Boolean | toggleMode | Set to true to keep any selections present in the list object.<br>If this parameter is set to false, selections made before accepting the list object search become alternative. |
| System.Boolean | softLock | Set to true to ignore locks; in that case, locked fields can be selected.<br>The default value is false. |

### Returns

| Type | Description |
| --- | --- |
| System.Threading.Tasks.Task&lt;System.Boolean&gt; |  |
