The tooltip format can be specified in a few different ways: as simple name of the extended property, as formatted extended property, or as format string which can use number of the extended properties.

        <pre><code class="lang-csharp">EllipseData ellipse = new EllipseData();

// Using of the single extended property name. ellipse.ToolTipFormat = "CNTRY_NAME";

// Using of the formatted extended property. // The '|' character is used to separate extended property name and its output format. ellipse.ToolTipFormat = "SUM_SQMI_A|F2";

// Format string with number of the extended properties. ellipse.ToolTipFormat = "{CNTRY_NAME} Miles: {SUM_SQMI_A|F2}, KM: {SUM_SQKM_A|F1}";

Dim ellipse As New EllipseData()
' Using of the single extended property name.
ellipse.ToolTipFormat = "CNTRY_NAME"
' Using of the formatted extended property.
' The '|' character is used to separate extended property name and its output format.
ellipse.ToolTipFormat = "SUM_SQMI_A|F2"
Format string with number of the extended properties.
ellipse.ToolTipFormat = "{CNTRY_NAME} Miles: {SUM_SQMI_A|F2}, KM: {SUM_SQKM_A|F1}"

ToolTipStyle

Style

Gets or sets the style applied to the toolTip.

public Style ToolTipStyle { get; set; }

ToolTipTemplate

DataTemplate

Gets or sets tooltip content template. Either ToolTipFormat or ToolTipTemplate should be specified. If both properties are set, then ToolTipTemplate will be used. You can bind elements in the tooltip template to extended properties using Data property of the ExtendedData object.

public DataTemplate ToolTipTemplate { get; set; }

Example:

        This example demonstrates how the tooltip template can be set.

        <pre><code class="lang-csharp"><DataTemplate x:Key="TooltipTemplate">
<Grid>
	<Grid.ColumnDefinitions>
		<ColumnDefinition Width="Auto" />
		<ColumnDefinition Width="Auto" />
	</Grid.ColumnDefinitions>
	<Grid.RowDefinitions>
		<RowDefinition Height="Auto" />
		<RowDefinition Height="Auto" />
		<RowDefinition Height="Auto" />
	</Grid.RowDefinitions>

	<TextBlock Grid.Column="0" Grid.Row="0" Text="Name:" />
	<TextBlock Grid.Column="1" Grid.Row="0" 
		Text="{Binding Path=Data[Name]}" />

	<TextBlock Grid.Column="0" Grid.Row="1" Text="Area:" />
	<TextBlock Grid.Column="1" Grid.Row="1" 
		Text="{Binding Path=Data[\{Area|F2\}]}" />

	<TextBlock Grid.Column="0" Grid.ColumnSpan="2" Grid.Row="2" 
		Text="{Binding Path=Data[Density\=\{Density|F1\} Population\=\{Population|F0\}]}" />
</Grid>
