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}"
