# Put a Mark on the clicked Location

If you want to mark the position where the user has clicked, you just have to handle the **MapMouseClick** event and add the desired mark element to the **InformationLayer** of the **RadMap** on the clicked location.

The following example will use a **RadMap** with one **InformationLayer**. The **InformationLayer** has its **ItemTemplate** property set. The **DataTemplate** contains a red **Ellipse**. In this example, the object that will be passed to the **InformationLayer** will be of type Location, so the **MapLayer.Location** property of the ellipse is bound to the **DataContext** of the template.

> tip More detailed information regarding the data binding can be found in the [Data Binding](https://www.telerik.com/products/wpf/documentation/controls/radmap/features/information-layer/data-binding) topic.

> tip To learn how to define a provider for the **RadMap**, read the [Providers](https://www.telerik.com/products/wpf/documentation/controls/radmap/features/providers/providers) topic.

Here is the code for the example:

```XAML
<telerik:RadMap x:Name="radMap"
	                Width="600"
	                Height="480"
	                MapMouseClick="radMap_MapMouseClick">
    <telerik:InformationLayer x:Name="informationLayer">
        <telerik:InformationLayer.ItemTemplate>
            <DataTemplate>
                <Ellipse telerik:MapLayer.Location="{Binding}"
	                            Width="20"
	                            Height="20"
	                            Stroke="Red"
	                            StrokeThickness="3"
	                            Fill="Transparent">
                    <telerik:MapLayer.HotSpot>
                        <telerik:HotSpot X="0.5"
	                                            Y="0.5" />
                    </telerik:MapLayer.HotSpot>
                </Ellipse>
            </DataTemplate>
        </telerik:InformationLayer.ItemTemplate>
    </telerik:InformationLayer>
</telerik:RadMap>
```

```C#
private void radMap_MapMouseClick(object sender, MapMouseRoutedEventArgs eventArgs)
{
    this.informationLayer.Items.Clear();
    this.informationLayer.Items.Add(eventArgs.Location);
}
```

```VB.NET
	Private Sub radMap_MapMouseClick(ByVal sender As Object, ByVal eventArgs As MapMouseRoutedEventArgs)
		Me.informationLayer.Items.Clear()
		Me.informationLayer.Items.Add(eventArgs.Location)
	End Sub
```
