call ComboBox method from MapTool

JackKelley1

In the SDK's Examples\MapExploration\GetMapCoordinates.cs, the map coordinates become available in HandleMouseDownAsync(...).

Afterwards, still in HandleMouseDownAsync(...), I need to invoke a method defined in a ComboBox, something like:

public void SearchXY (double x, double y) 
{ this.queryRows = this.database.Query(x, y); UpdateCombo(); }

How can I obtain a reference to this ComboBox?

Or is an event needed?

Yes Gintautas, that code in Combo Box Reload showed the way.

The add-in has classes Module1, MapTool1, ComboBox1, plus my own Database.

The required call from MapTool1 works fine and is simply

Module1.Current.ComboBox1.SearchXY(x, y);

Visual Studio made some suggestions to simplify the code (and the Config.daml needed no change).

In brief, the additions / modifications were:

Module1:

public ComboBox1 ComboBox1 { get; set; } = null;

ComboBox1: 

public ComboBox1()
{
    if (Module1.Current == null) return;
    Module1.Current.ComboBox1 = this;
    this.database = new Database();
    //UpdateCombo();
}
