C# Vérifier entrée en dynamique créée richtextbox

Question

Voici ce que j'ai:

private void button1_Click(object sender, EventArgs e) 
    { 
     //Creating the RichTextBox 
     RichTextBox rtb = new RichTextBox(); 
     rtb.Location = new Point(20, 20); 
     rtb.Width = 400; 
     rtb.Height = 300; 
     rtb.BackColor = Color.White; 
     rtb.Font = new Font("Mistral", 16, FontStyle.Regular); 
     int size = rtb.TextLength; 
     rtb.AcceptsTab = true; 
     rtb.ScrollBars = RichTextBoxScrollBars.Both; 
     rtb.ReadOnly = false; 
     rtb.MaxLength = rtb.TextLength; 
     rtb.ShortcutsEnabled = true; 
     rtb.EnableAutoDragDrop = true; 
     Controls.Add(rtb); 
} 

Je veux capitaliser l'entrée de l'utilisateur en utilisant

string text = rtb.Text.ToUpper(); 
rtb.Text = text; 
rtb.SelectionStart = rtb.Text.Length; 

Pour ce faire, je dois obtenir l'entrée de l'utilisateur constamment dans rtb.Text Comment puis-je y parvenir? Merci d'avance.

Un peu déconner:

private void createDynamicRTB() 
    { 
     rtb.Location = new Point(20, 20); 
     rtb.Width = 400; 
     rtb.Height = 300; 
     rtb.BackColor = Color.White; 
     rtb.Font = new Font("Mistral", 16, FontStyle.Regular); 
     int size = rtb.TextLength; 
     rtb.AcceptsTab = true; 
     rtb.ScrollBars = RichTextBoxScrollBars.Both; 
     rtb.ReadOnly = false; 
     rtb.MaxLength = rtb.TextLength; 
     rtb.ShortcutsEnabled = true; 
     rtb.EnableAutoDragDrop = true; 
     Controls.Add(rtb); 
    } 
    RichTextBox rtb = new RichTextBox(); 
    private void button1_Click(object sender, EventArgs e) 
    { 
     //Capitalize 
     rtb.Text = rtb.Text.ToUpper(); 


    } 

ou ...

RichTextBox rtb = new RichTextBox(); 
    private void Form1_Load(object sender, EventArgs e) 
    { 
     createDynamicRTB(); 
     rtb.TextChanged += Rtb_TextChanged;//use this to capitalize after leaving 
     rtb.KeyPress += Rtb_KeyPress;//use this to capitalize immediately 
    } 

    private void Rtb_KeyPress(object sender, KeyPressEventArgs e) 
    { 
     rtb.Text = rtb.Text.ToUpper(); 
    } 

    private void Rtb_TextChanged(object sender, EventArgs e) 
    { 
     //Capitalize 
     rtb.Text = rtb.Text.ToUpper(); 
    } 

    private void createDynamicRTB() 
    { 
     rtb.Location = new Point(20, 20); 
     rtb.Width = 400; 
     rtb.Height = 300; 
     rtb.BackColor = Color.White; 
     rtb.Font = new Font("Mistral", 16, FontStyle.Regular); 
     int size = rtb.TextLength; 
     rtb.AcceptsTab = true; 
     rtb.ScrollBars = RichTextBoxScrollBars.Both; 
     rtb.ReadOnly = false; 
     rtb.MaxLength = rtb.TextLength; 
     rtb.ShortcutsEnabled = true; 
     rtb.EnableAutoDragDrop = true; 
     Controls.Add(rtb); 
    }
