## Description

How to increase the tooltip duration for the items in the VisualizationLayer.

## Solution

1. Subscribe to the **MapShapeVisualizationCreated** event of VisualizationLayer.
2. Use the **ToolTipService.SetShowDuration** method to set the tooltip duration for the generated visual element. To get the visual element use the Visualization property of the event arguments.

```C#
	private void VisualizationLayer_MapShapeVisualizationCreated(object sender, MapShapeOperationEventArgs e)
	{
		ToolTipService.SetShowDuration(e.Visualization, 1000);
	}
```
