// 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}";</code></pre>
<pre><code class="lang-csharp">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"
