# Getting Started with WinForms Overlay Screen

This tutorial will walk you through how you can use the **Overlay Screen**.

The overlay form can be activated throught the **RadOverlayManager.Show()** method. This method accept parameter of type **Control** or **Form**. When the Show() method is called, the Overlay form will take the size of the control which is passed as a parameter and it will appear on top of that control. This will make the control beneath the screen inactive. Rotating dots in the center will notify the user that currently a long running operation is being executed. After this operation is finished, we can close the overlay screen by calling the **RadOverlayManager.Close()** static method.

## Show Overlay

```C#
RadOverlayManager.Show(this.radGridView1);
```

```VB.NET
RadOverlayManager.Show(Me.radGridView1)
```

```C#

RadOverlayManager.Show(this.radGridView1);
	

```

```VB.NET

RadOverlayManager.Show(this.radGridView1)


```

## Close Overlay

```C#
RadOverlayManager.Close();
```

```VB.NET
RadOverlayManager.Close()
```

```C#

RadOverlayManager.Close();
	

```

```VB.NET

RadOverlayManager.Close()


```
