# Tailent.Control.ControlExists

This method checks whether or not a defined control identifier exists and returns a boolean value.

The method takes only one parameter, which is the control identifier name as defined in the "UI Browser" tab.

**Example usage**

```
// bool result = Tailent.Control.ControlExists("ctrlId");
```

To visualize the output, the "result" variable can be printed on the screen:

```
// MessageBox.Show(result.ToString());
```
