在Windows窗体的keydown事件中，ProcessTabKey（true）在c＃splitcontainer上不起作用

Question

i am trying to use ProcessTabKey() method not working on c# splitcontainer at keydown event of windows form

    public Form1()
    {
        InitializeComponent();
    }
    private void Form1_Load(object sender, EventArgs e)
    {
        this.BringToFront();
        this.Focus();
        this.KeyPreview = true;
    }
    private void Form1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Enter)
        {

                e.Handled = true;
                this.ProcessTabKey(true);
        }

    }

Answer 1

Your code is correct. Ensure that all the controls you want to select have their TabStop property set to true.

Answer 2

Use SendKeys.send("{tab}"); instead of this.ProcessTabKey(true);
