To load my ComboBox at the beginning I used the mine method LoadDataFromDB() in the InitializeComponent() method, but there is an warning says:

The code within the method 'InitializeComponent' is generated by the designer and should not be manually modified

So where can I load my ComboBox?

Use form's constructor 

public Form1()
{
    InitializeComponent();
    LoadDataFromDB();
}

Or (sometimes better) Form.Load event handler (it will be added automatically when you double-click form in designer):

private void Form1_Load(object sender, EventArgs e)
{
    LoadDataFromDB();
}

Another option is overriding OnLoad method of form.

NOTE: You see this warning, because InitializeComponent is generated by designer, and it will be completely re-generated when you'll change something in designer (add some control, move or resize some control, change color etc). Thus all your changes to this method will gone.

Directly after InitializeComponent is called, or as long as its after InitializeComponent().

public FormName()
{
   InitializeComponent();
   LoadDataFromDB();
}

Note: You may not see these controls in the Visual studio designer view

You don't need to load it in InitializeComponent method. Just after it you can call your method LoadDataFormDB().

InitializeComponent();
LoadDataFormDB();

You can read also, the comments above the method which says:

'NOTE: The following procedure is required by the Windows Form Designer
'It can be modified using the Windows Form Designer. 
'Do not modify it using the code editor.
