<igMap:MapLayer x:Name="worldLayer" DataMapping="Name=CountryName; Value=BirthRate" ToolTip="{} Birth Rate: {Value:n0}">
</igMap:MapLayer>
You can provide a custom format string to control the way data is displayed in xamMap™. MapElement properties such as Caption and ToolTip allow the use of standard .NET format strings. Other displayed values can also be customized; Color Swatch Pane labels can be customized by setting the LabelFormatString property to any standard format.
The following code shows you how to display the tooltip as a number with zero decimal places.
In XAML:
<igMap:MapLayer x:Name="worldLayer" DataMapping="Name=CountryName; Value=BirthRate" ToolTip="{} Birth Rate: {Value:n0}">
</igMap:MapLayer>
In Visual Basic:
' Set ToolTip format
For Each element As MapElement In layer.Elements
element.ToolTip = String.Format("Birth Rate: {0:n0}", element.Value)
Next
In C#:
foreach (MapElement element in layer.Elements)
{
element.ToolTip = string.Format("Birth Rate: {0:n0}", element.Value);
}
