如何在运行时添加多个文本框

推荐答案

void existingTextBox_LostFocus(object sender, EventArgs e)
    {
    TextBox existing = sender as TextBox;
    if (existing != null)
        {
        TextBox newTextBox = new TextBox();
        newTextBox.LostFocus += new EventHandler(existingTextBox_LostFocus);
        newTextBox.Location = new Point(existing.Location.X, existing.Location.Y + 30);
        newTextBox.Size = existing.Size;
        Controls.Add(newTextBox);
        }
    }
