FixedMiniMapBehavior Class

This class provides the fixed mini map behavior.

Namespace: DevExpress.XtraMap

Assembly: DevExpress.XtraMap.v18.1.dll

Declaration

C#

public class FixedMiniMapBehavior :
    MiniMapBehavior

VB.NET

Public Class FixedMiniMapBehavior
    Inherits MiniMapBehavior

Remarks

• This class introduces the FixedMiniMapBehavior.CenterPoint property to specify a center point of the mini map and the FixedMiniMapBehavior.ZoomLevel property to set the zoom level of the mini map.

• When a mini map operates in this mode, its center point and zoom level are fixed. The following images demonstrates fixed behavior mode.

  

Example

This example shows how to customize mini map behavior.

To do this, assign the MiniMapBehavior class descendant object to the MiniMap.Behavior property and specify the object’s properties.

Form1.cs

List<MiniMapBehavior> behaviors = new List<MiniMapBehavior> { 
    new FixedMiniMapBehavior(), 
    new DynamicMiniMapBehavior()
};

private void Form1_Load(object sender, EventArgs e) {
    cbAlignment.DataSource = Enum.GetValues(typeof(MiniMapAlignment));
    cbBehavior.DataSource = behaviors;
}
private void cbBehavior_SelectedIndexChanged(object sender, EventArgs e) {
    MiniMapBehavior behavior = cbBehavior.SelectedValue as MiniMapBehavior;
    if (behavior == null) return;
    propertyGrid.SelectedObject = behavior;

    if (mapControl.MiniMap == null) return;
    mapControl.MiniMap.Behavior = behavior;

}
