How can i change my winform to another language

Question

I have a winform and i changed the language of the form to Dutch. After that i edit the name of the groupboxes labels etc. The moment i change a radiobutton do Dutch it only changes the namess of the groupboxes and not the labels en textboxes.

I changed the language of my form to Dutch. Then i made 2 Radiobuttons Dutch and German. the moment i press Dutch language radiobutton it only changes the name of the groupboxes and the other labels and stuff stay the same.

This is the methode and code i used.

  private void ChangeLanguage(string lang)
        {
            foreach (Control c in Controls)
            {
                ComponentResourceManager resources = new ComponentResourceManager(typeof(Form1));
                resources.ApplyResources(c, c.Name, new CultureInfo(lang));
            }
        }

 private void DutchRadiobutton_CheckedChanged(object sender, EventArgs e)
        {
            ChangeLanguage("nl-NL");

        }

I want the whole form to change and every control in it when i click the radiobutton dutch language. For now only the groupbox names changes but the labels and textboxes in it stay the same langauge.

You need to recursively loop through the controls, otherwise you don't apply the changes to the inner controls of the GroupBox(es). — Odrai, Mar 26 '19 at 18:18
Please have a look at [C# Recursion](https://www.dotnetperls.com/recursion) — Odrai, Mar 26 '19 at 18:20

Recursion example

The input of this method could be 'this', which is e.g. a reference of your control or GroupBox.

private void ApplyChanges(Control ctrl)
{
    foreach (Control c in ctrl.Controls)
    {
        // Do something

        Debug.WriteLine($"ctrl name: {c.Name}"); // Test code, just to print the control name(s).
        if (c.Controls != null && c.Controls.Count > 0)
        {
            ApplyChanges(ctrl);
        }
    }
}

Language change method

private void ApplyResources(Control parent, CultureInfo culture)
{
    _componentResourceManager.ApplyResources(parent, parent.Name, culture);

    foreach (Control ctl in parent.Controls)
    {
        ApplyResources(ctl, culture);
    }
}

Or have a look at the existing question/answer: 'Proper way to change language at runtime'
