3 ways to traverse form controls in C# WinForm

1. Looping traversal

private void GetControls(Control fatherControl)
{
     sonControls = ;
    foreach (Control control in sonControls)
    {
        ();
    }
}

Result: You can obtain Panel, GroupBox, TabControl and other controls
Problem: The child controls on Panel and other controls cannot be obtained

2. Recursive traversal

private void GetControls(Control fatherControl)
{
     sonControls = ;
    foreach (Control control in sonControls)
    {
        ();
        if ( != null)
        {
            GetControls(control);
        }
    }
}

Result: Most controls can be obtained
Problem: Timer, ContextMenuStrip and other controls cannot be obtained

3. Use reflection

private void GetControls(Control fatherControl)
{
    [] fieldInfo = ().GetFields( | );
    for (int i = 0; i < ; i++)
    {
        (fieldInfo[i].Name);
    }
}

Result: All controls are retrieved

DevExpressThe control cannot be usedIt can only be obtained by reflection method, as follows:

public void SearchBarManager()
{
    Type FormType = ();
    FieldInfo[] fi = ( |  | );
    foreach (FieldInfo info in fi)
    {
        if ( == typeof())
        {
             bar = ((this)) as ;
            foreach ( bi in )
            {
                ();
            }
        }
    }
}
