Programmatically Launching Windows 10 Emoji Hotkeys

Open Emoji panel in a Windows Forms or WPF application

You need to handle the desired event, then first Focus to your control, then using CoreInputView.GetForCurrentView get the core input view for the current window, and then call its TryShow method and pass CoreInputViewKind.Emoji to the method. For example:

//using Windows.UI.ViewManagement.Core;
private async void button1_Click(object sender, EventArgs e)
{
    textBox1.Focus();
    CoreInputView.GetForCurrentView().TryShow(CoreInputViewKind.Emoji);
}

Note: For Windows Forms or WPF project, before using above code, you need to configure your project to be able to call Windows Runtime APIs in desktop apps.
