# RadToolTip

**RadToolTip** is a class derived from the standard **ToolTip** class in the **System.Windows.Forms** namespace. The need of a derived class arisen from the fact that the ToolTips needs a Control in order to be shown. **RadToolTip** encapsulates all that functionality inside of it, which makes it very flexible, requiring only the most basic parameters in order to be shown (only the text is required).

## Usage

**RadToolTip** has a **Show** method with 6 overloads. The base class also has a **Show** method, you can tell them apart by the fact that **RadToolTip** does not require an **IWin32Window** instance. The first example shows how you can create the tooltip. Below it are all overloads coming from **RadToolTip**:

 

 

```C#
RadToolTip toolTip = new RadToolTip();

```

```VB.NET
Dim toolTip As New RadToolTip()

```

 

* Shows a RadToolTip with the specified text on the position of the mouse with the default duration.

 

 

```C#
toolTip.Show("Tooltip text");

```

```VB.NET
toolTip.Show("Tooltip text")

```

 

* Shows a RadToolTip with the specified text on the position of the mouse and with the specified duration.

 

 

```C#
toolTip.Show("Tooltip text", 2000);

```

```VB.NET
toolTip.Show("Tooltip text", 2000)

```

 

* Shows a RadToolTip with the specified text on the specified position relative to the screen coordinates and with the default duration.

 

 

```C#
toolTip.Show("Tooltip text", Cursor.Position);

```

```VB.NET
toolTip.Show("Tooltip text", Windows.Forms.Cursor.Position)

```

 

* Shows a RadToolTip with the specified text on the specified X and Y coordinates relative to the screen coordinates and with the default duration.

 

 

```C#
toolTip.Show("Tooltip text", 500, 500);

```

```VB.NET
toolTip.Show("Tooltip text", 500, 500)

```



* Shows a RadToolTip with the specified text on the specified X and Y coordinates relative to the screen coordinates and with the specified duration.

 

 

```C#
toolTip.Show("Tooltip text", 500, 500, 2000);

```

```VB.NET
toolTip.Show("Tooltip text", 500, 500, 2000)

```

 

* Shows a RadToolTip with the specified text on the specified position relative to the screen coordinates and with the specified duration.

 

 

```C#
toolTip.Show("Tooltip text", new Point(500,500), 2000);

```

```VB.NET
toolTip.Show("Tooltip text", New Point(500, 500), 2000)

```

 

> important You can also hide an active ToolTip at any time using the **Hide** method. This method accepts no arguments, the base Hide method accepts an **IWin32Window** instance.

## Example: Show a RadToolTip on a RadForm.

Create a new RadForm and in the code behind subscribe to its **Click** event. Replace the automatically generated event handler code with the following:

 

 

```C#
void RadToolTipExample_Click(object sender, EventArgs e)
{
    RadToolTip newToolTip = new RadToolTip();
    newToolTip.Show("A tooltip which appears at mouse position", 2000);
}

```

```VB.NET
Private Sub RadToolTipExample_Click(sender As Object, e As EventArgs)
    Dim newToolTip As New RadToolTip()
    newToolTip.Show("A tooltip which appears at mouse position", 2000)
End Sub

```

 

Now, every time you click on the form you should see a ToolTip which will hide after 2 seconds.

> note **RadToolTip** is a derivative of MS **Tooltip**. In order to customize its style, you can handle the **Draw** event. Additional information is available here: [ToolTip.Draw](https://msdn.microsoft.com/en-us/library/system.windows.forms.tooltip.draw\(v=vs.110\).aspx).
