Syntax

public abstract class AsyncReaderBase : RadObject, IDisposable, INotifyPropertyChanged, ICustomTypeDescriptor

Constructors

AsyncReaderBase()

Declaration
protected AsyncReaderBase()

Fields

ClearLayerProperty

Declaration
public static readonly RadProperty ClearLayerProperty
Field Value
RadProperty

CoordinateConverterProperty

Declaration
public static readonly RadProperty CoordinateConverterProperty
Field Value
RadProperty

ExtendedPropertySetProperty

Declaration
public static readonly RadProperty ExtendedPropertySetProperty
Field Value
RadProperty

ToolTipFormatProperty

Declaration
public static readonly RadProperty ToolTipFormatProperty
Field Value
RadProperty

Properties

ClearLayer

Gets or sets the ClearLayer property. If it is set to true, then the reader clears its information layer after reading.

Declaration
public bool ClearLayer { get; set; }
Property Value
System.Boolean

CoordinateConverter

Gets or sets the CoordinateConverter applied to the reader.

Declaration
public ICoordinateConverter CoordinateConverter { get; set; }
Property Value
ICoordinateConverter

ExtendedPropertySet

Gets or sets extended property set which will be used during shape file (KML or ESRI) reading.

Declaration
public ExtendedPropertySet ExtendedPropertySet { get; set; }
Property Value
ExtendedPropertySet

Remarks

Can be null. In this case extended property set will be created depends on the extended data available in the KML file or in the attributes file (DBF).

Layer

Target layer.

Declaration
public MapLayer Layer { get; set; }
Property Value
MapLayer

ToolTipFormat

Gets or sets tooltip format. Either ToolTipFormat or ToolTipTemplate should be specified. If both properties are set, then ToolTipTemplate will be used.

Declaration
public string ToolTipFormat { get; set; }
Property Value
System.String

Examples

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.

this.visualizationLayer.Reader = new AsyncShapeFileReader();

// Using of the single extended property name.
this.visualizationLayer.Reader.ToolTipFormat = "CNTRY_NAME";

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

// Format string with number of the extended properties.
this.visualizationLayer.Reader.ToolTipFormat = "{CNTRY_NAME} Miles: {SUM_SQMI_A|F2}, KM: {SUM_SQKM_A|F1}";
Me.visualizationLayer.Reader = New AsyncShapeFileReader()

' Using of the single extended property name.
Me.visualizationLayer.Reader.ToolTipFormat = "CNTRY_NAME"

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

 Format string with number of the extended properties.
Me.visualizationLayer.Reader.ToolTipFormat = "{CNTRY_NAME} Miles: {SUM_SQMI_A|F2}, KM: {SUM_SQKM_A|F1}"
<telerik:AsyncShapeFileReader Source="/Telerik.RadMap.Silverlight;component/africa"
    ToolTipFormat="CNTRY_NAME">

<telerik:AsyncShapeFileReader Source="/Telerik.RadMap.Silverlight;component/africa"
    ToolTipFormat="SUM_SQMI_A|F2">

<telerik:AsyncShapeFileReader Source="/Telerik.RadMap.Silverlight;component/africa"
    ToolTipFormat="{}{CNTRY_NAME} Miles: {SUM_SQMI_A|F2}, KM: {SUM_SQKM_A|F1}">
.
