多个GroupBox中每个按钮的Button_click事件(代码中)

我有多个groupbox
,其中一个包含一个问题和一些答案,每个GroupBox
中都有button
答案。我在Form_Load方法中创建GroupBox
及其控件,而不是手动创建。如何为每个button
处理button_click
事件?我认为没有必要为每个button
编写这个句柄方法,因为只有两个不同的button_handler:对于只有一个正确答案的问题,以及对于多个答案可以正确的问题。我的问题看起来像:
我的GroupBox结构:
int loc = 20;
for (int i = 0; i < 10; i++)
{
GroupBox gb = new GroupBox();
gb.Name = "GroupBox" + (i + 1);
gb.Size = new Size(500, 200);
gb.Location = new Point(40, loc);
gb.BackColor = System.Drawing.Color.Aquamarine;
Label q_text = new Label(); // текст питання
q_text.Name = "label" + (i + 1);
q_text.Text = "Питання" + (i + 1);
q_text.Font = new Font("Aria", 10, FontStyle.Bold);
q_text.Location = new Point(10, 10);
gb.Controls.Add(q_text);
int iter = q_text.Location.Y + 30;
if (i <= 5)
{
foreach (string key in questions[i].answers.Keys)
{
RadioButton rb = new RadioButton();
rb.Text = key;
rb.Size = new Size(120, 25);
rb.Location = new Point(q_text.Location.X + 10, iter);
iter += 30;
gb.Controls.Add(rb);
}
}else
if (i > 5)
{
foreach (string key in questions[i].answers.Keys)
{
CheckBox rb = new CheckBox();
rb.Text = key;
rb.Size = new Size(120, 25);
rb.Location = new Point(q_text.Location.X + 10, iter);
iter += 30;
gb.Controls.Add(rb);
}
}
Button b = new Button();
b.Name = "button" + (i + 1);
b.Text = "Answer";
b.Location = new Point(gb.Size.Width - 120, gb.Size.Height - 30);
gb.Controls.Add(b);
this.Controls.Add(gb);
loc += 200;
}
您可以为按钮创建一个常规点击事件:
Button b = new Button();
b.Name = "button" + (i + 1).ToString();
b.Click += b_Click;
在该方法中,检查发送者以查看点击了哪个按钮:
void b_Click(object sender, EventArgs e) {
Button b = sender as Button;
if (b != null) {
GroupBox gp = b.Parent as GroupBox;
int bIndex = Convert.ToInt32(b.Name.Substring(6)) - 1;
MessageBox.Show(string.Format("I'm clicking {0}, question index #{1}",
gp.Name, bIndex));
}
}
之后,您必须检查GroupBox子控件的检查值以及questions[bIndex].answers
变量中允许的答案。
