pass event from UserControl to parent form

Question

I don't know how to register event that happened inside of user control in my form. Form has 3 FloatLayoutPanels Each FloatLayoutPanel has list of UserControls. Each UserControl has ComboBox I would like to be able to move UserControls between FloatLayoutPanels on ComboBox onvaluechanged event. In order to do that I would need to register that event from UserControl ComboBox happened in the main form

Here is my UserControl constructor:

public event EventHandler SelectedStatusValueChanged;


public ucNarudzba()
    {
        InitializeComponent();
        this.cmbPromjenaStanja.SelectedValueChanged += new System.EventHandler(this.cmbPromjenaStanja_SelectedValueChanged);
    }

this is my combobox SelectedValueChanged event

 private void cmbPromjenaStanja_SelectedValueChanged(object sender, EventArgs e)
    {
        if (SelectedStatusValueChanged != null)
            SelectedStatusValueChanged(sender, e);
    }

Then in my form I should access event something like this (not sure if this is correct)

private void ucNarudzba_SelectedStatusValueChanged(object sender, EventArgs e)
    {
        // Do what I want
        
    }

and if it is correct I dont know how to write code in form's designer.cs file that would call this event!

So I am asking for feedback if this is ok method to get event data from user control to form, and help with calling event from form's designer.cs file.

Any help is appreciated!!!!
