MapItem.EnableSelection Property

Indicates whether a map item can be selected.

Namespace: DevExpress.XtraMap

Assembly: DevExpress.XtraMap.v21.2.dll

NuGet Packages: DevExpress.Win.Design, DevExpress.Win.Map

Declaration

C#

[DefaultValue(DefaultBoolean.Default)]
public DefaultBoolean EnableSelection { get; set; }

VB.NET

<DefaultValue(DefaultBoolean.Default)>
Public Property EnableSelection As DefaultBoolean

Property Value

Type	Default	Description
DefaultBoolean	Default	true if a map item can be selected; otherwise, false.

Available values:

Name	Description
True	true. DefaultBoolean.True has a constant value of 0, while the standard true value corresponds to a value of 1. In Visual Basic, do not use implicit conversion of Boolean values to DefaultBoolean, and vice versa, as the conversion may produce incorrect results.
False	false. DefaultBoolean.False has a constant value of 1, while the standard false value corresponds to a value of 0. In Visual Basic, do not use implicit conversion of Boolean values to DefaultBoolean, and vice versa, as the conversion may produce incorrect results.
Default	The default behavior determined by the control’s logic.

Remarks

The MapItem.EnableSelection property has a higher priority than the MapItemsLayerBase.EnableSelection property specified for the map layer that contains the map item.

The following example disables selection for all items on the itemsLayer except the MapEllipse item:

C#

private void Form1_Load(object sender, EventArgs e) {
    //...
    // Create a layer to display vector items.
    VectorItemsLayer itemsLayer = new VectorItemsLayer();
    itemsLayer.EnableSelection = false;
    map.Layers.Add(itemsLayer);

    // Create storage for map items and generate them.
    MapItemStorage storage = new MapItemStorage();
    MapItem[] myItems = GetMapItems();
    storage.Items.AddRange(myItems);
    itemsLayer.Data = storage;
}

// Create an array of map items.
MapItem[] GetMapItems() {
    return new MapItem[] {
        new MapDot() { Location = new GeoPoint(55, 0), Size=30},
        new MapEllipse() { Location = new GeoPoint(40, 12),  Width = 2000, Height = 1000, 
                           EnableSelection = DefaultBoolean.True },
        new MapRectangle() {  Location = new GeoPoint(60, 13), Width = 1500, Height = 1000 }
    };
}

VB.NET

Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs)
    '...
    ' Create a layer to display vector items.
    Dim itemsLayer As VectorItemsLayer = New VectorItemsLayer()
    itemsLayer.EnableSelection = False
    map.Layers.Add(itemsLayer)

    ' Create storage for map items and generate them.
    Dim storage As MapItemStorage = New MapItemStorage()
    Dim myItems As MapItem() = GetMapItems()
    storage.Items.AddRange(myItems)
    itemsLayer.Data = storage
End Sub

' Create an array of map items.
Private Function GetMapItems() As MapItem()
    Return New MapItem() {New MapDot() With {
        .Location = New GeoPoint(55, 0),
        .Size = 30
    }, New MapEllipse() With {
        .Location = New GeoPoint(40, 12),
        .Width = 2000,
        .Height = 1000,
        .EnableSelection = DefaultBoolean.[True]
    }, New MapRectangle() With {
        .Location = New GeoPoint(60, 13),
        .Width = 1500,
        .Height = 1000
    }}
End Function
