C#动态窗体急！！！分不够加！！！

[睡神在睡觉]

对动态创建的窗体上动态创建的控件事件怎么来操作，谢谢了，下面给出部分代码，请大虾指教，分不够加~！！
原窗体中代码：
string GInfo;
private void Next_Click(object sender, EventArgs e)
{
Form work = new Form();
work.Text = "轮船卸货作业";
work.MaximizeBox = false;
work.MinimizeBox = false;
work.WindowState = System.Windows.Forms.FormWindowState.Maximized;
TextBox Inof = new TextBox();
Info.Text = "";
GInfo = "";
Button bt = new Button();
bt.Location = new System.Drawing.Point(163, 90);
bt.Size = new System.Drawing.Size(64, 23);
bt.Text = "Begin";
bt.Click += new EventHandler(bt_Click);
Tabcon.Size = new System.Drawing.Size(238, 269);
work.Controls.Add(Tabcon);
work.Show();
}
void bt_Click(object sender, EventArgs e)
{
//在此处将Info.Text此时的值赋给GInfo，怎么实现？
//在此处设置bt的属性，怎么来实现？
}

楼主之前的贴子的结分很有趣,全部平均给分,SO,不想回答了...

虽然分不多,可是辛苦回答问题却得不到合理的报酬,

既然没有随意,那就算了~

你可以试下在form_load时加载控件，
然后遍历controls，应可以的

7楼
foreach(Control c in work.Controls) //this-->work
{
if(c is TextBox)
{
TextBox tb = c as TextBox;
GInfo = tb.Text.Trim();
}
}
这里能打出work么？我怎么打不出来？

private void button2_Click(object sender, EventArgs e)
        {
            Form work = new Form();
            work.Text = "轮船卸货作业";
            work.MaximizeBox = false;
            work.MinimizeBox = false;
            work.WindowState = System.Windows.Forms.FormWindowState.Maximized;
            TextBox Inof = new TextBox();
            Inof.Name = "Inof";
            Info.Text = "";
            GInfo = "";
            Button bt = new Button();
            bt.Location = new System.Drawing.Point(163, 90);
            bt.Size = new System.Drawing.Size(64, 23);
            bt.Text = "Begin";
            bt.Click += new EventHandler(bt_Click);
            Tabcon.Size = new System.Drawing.Size(238, 269);
            work.Controls.Add(Tabcon);
            work.Show(); 
        }
void bt_Click(object sender, EventArgs e)
        {
            //在此处将Info.Text此时的值赋给GInfo，怎么实现？            
            Button bt = sender as Button;
            this.GInfo = ((Form)bt.Parent).Controls.Find("Inof",false)[0].Text;            
            //在此处设置bt的属性，怎么来实现？ 
             bt.Text = "Clicked!!";
        }

晕，你没看到work的定义写在外边做全局变量吗~~~

string GInfo; 
Form work ;  //全局变量
        private void Next_Click(object sender, EventArgs e) 
        { 
            work = new Form();   //这里实例化
            work.Name = "frmShip";
            work.Text = "轮船卸货作业"; 

       ...
        ...

[smntbk]

你的button2_Click事件中代码不少问题，能调试过去？
bt_Click事件中，sender对象就是bt，转换类型后可以直接设置其属性(转成TextBox那个判断当然进不去了)。
至于获得TextBox中的值，那就找到bt的父容器Form窗体，用Form.Controls.Find()方法或者直接遍历Form找到TextBox控件对其操作。
LZ以前不少都是关于动态创建控件的帖子，其实如果好好琢磨琢磨诸位的回答，相信在这一块应该没有问题的。

[slimfeng]

同意7楼的做法，需要将Form作为全局变量，然后遍历搜索相应控件

[virusswb]

string GInfo;
private void Next_Click(object sender, EventArgs e)
{
Form work = new Form();
work.Text = "轮船卸货作业";
work.MaximizeBox = false;
work.MinimizeBox = false;
work.WindowState = System.Windows.Forms.FormWindowState.Maximized;
TextBox Inof = new TextBox();
Info.Text = "";
GInfo = "";
Button bt = new Button();
bt.Location = new System.Drawing.Point(163, 90);
bt.Size = new System.Drawing.Size(64, 23);
bt.Text = "Begin";
bt.Click += new EventHandler(bt_Click);
Tabcon.Size = new System.Drawing.Size(238, 269);
work.Controls.Add(Tabcon);
work.Show();
}
void bt_Click(object sender, EventArgs e)
{
//在此处将Info.Text此时的值赋给GInfo，怎么实现？
//在此处设置bt的属性，怎么来实现？
}
你根本就没有把控件加入窗体中啊，你就加了一个tabcon，这是什么东西啊，没有看到定义啊
应该把textbox和button加入啊，就是你的Inof和bt啊，
再说你的错别太多了，开始是inof，后面就是info

[睡神在睡觉]

不好意思，刚才没看清，你这样Form work ;来定义成全局的，在窗口初始化的时候不就创建这个窗体了么？关闭了这个窗体还怎么来再创建？刚才试验了下，好像是没获取到创建的work实例

[virusswb]

这个是可以运行的，看来你需要学的还很多，很多的概念还没有搞清楚，以后先想好在写代码了

string GInfo;
        Form work;
        private void Next_Click(object sender, EventArgs e)
        {
            work = new Form();
            work.Text = "轮船卸货作业";
            work.MaximizeBox = false;
            work.MinimizeBox = false;
            work.WindowState = System.Windows.Forms.FormWindowState.Maximized;
            TextBox Info = new TextBox();
            Info.Name = "txtInfo";
            Info.Text = "";
            GInfo = "";
            Button bt = new Button();
            bt.Location = new System.Drawing.Point(163, 90);
            bt.Size = new System.Drawing.Size(64, 23);
            bt.Text = "Begin";
            bt.Click += new EventHandler(bt_Click);
            //Tabcon.Size = new System.Drawing.Size(238, 269);
            work.Controls.Add(Info);
            work.Controls.Add(bt);
            work.Show();
        }
        void bt_Click(object sender, EventArgs e)
        {
            //在此处将Info.Text此时的值赋给GInfo，怎么实现？
            
            foreach (Control c in work.Controls)
            {
                if (c.Name == "txtInfo")
                {
                    GInfo = c.Text;
                    MessageBox.Show(GInfo);
                    break;
                }
            }
                //在此处设置bt的属性，怎么来实现？
            ((Button)sender).Text = "刚才你点击了我";
        }

[chinaicm]

代码里有一些变量不清楚是那里来的,我修改了一下.

        string GInfo; 
        private void button1_Click(object sender, EventArgs e)
        {
            Form work = new Form();
            work.Text = "轮船卸货作业";
            work.MaximizeBox = false;
            work.MinimizeBox = false;
            work.WindowState = System.Windows.Forms.FormWindowState.Maximized;
            TextBox Info = new TextBox();
            Info.Text = "";
            Info.Name = "hello";//这里给TextBox的Name赋个值,在下面便于找到
            work.Controls.Add(Info);
            GInfo = "";
            Button bt = new Button();
            bt.Location = new System.Drawing.Point(163, 90);
            bt.Size = new System.Drawing.Size(64, 23);
            bt.Text = "Begin";
            bt.Click += new EventHandler(bt_Click);
            bt.Size = new System.Drawing.Size(238, 269);
            bt.Name = "btnhello";
            work.Controls.Add(bt);
            work.Show(); 
        }

        void bt_Click(object sender, EventArgs e)
        {
            //在此处将Info.Text此时的值赋给GInfo，怎么实现？ 
            Button btn = sender as Button;
            Form form = btn.FindForm();
            TextBox tbx = form.Controls["hello"] as TextBox;
            GInfo = tbx.Text;
            //在此处设置bt的属性，怎么来实现？             
            Button btnHello = form.Controls["btnhello"] as Button;
        }

[睡神在睡觉]

string GInfo;

{
Form work = new Form();
work.Text = "轮船卸货作业";
work.MaximizeBox = false;

work.Controls.Add(bt);
work.Controls.Add(Info);
work.Show();
}
void bt_Click(object sender, EventArgs e)
{
//在此处将Info.Text此时的值赋给GInfo，怎么实现？
//在此处设置bt的属性，怎么来实现？

从新贴一遍，昨晚上粘来粘去粘乱了，不好意思

private void button2_Click(object sender, EventArgs e)
        {
            Form work = new Form();

            work.MaximizeBox = false;

            work.WindowState = System.Windows.Forms.FormWindowState.Maximized;
            TextBox Inof = new TextBox();
            Inof.Name = "Inof";
            Info.Text = "";
            GInfo = "";
            Button bt = new Button();
            bt.Location = new System.Drawing.Point(163, 90);
            bt.Size = new System.Drawing.Size(64, 23);
            bt.Text = "Begin";
            bt.Click += new EventHandler(bt_Click);
            Tabcon.Size = new System.Drawing.Size(238, 269);
            work.Controls.Add(Tabcon);
            work.Show(); 
        }
void bt_Click(object sender, EventArgs e)
        {
            //在此处将Info.Text此时的值赋给GInfo，怎么实现？            
            Button bt = sender as Button;
            this.GInfo = ((Form)bt.Parent).Controls.Find("Inof",false)[0].Text;            
            //在此处设置bt的属性，怎么来实现？ 
             bt.Text = "Clicked!!";
        }

引用的，但是可以的。

[睡神在睡觉]

确实，楼上几位说的方法我都试过了，单独的Demo中运行的确都行，但是加到程序中总是不进if语句。。莫非添加在TabControl这个控件在窗体上找不到？

[assky124]

我也在做一个差不多的程序，
解决思路如下：
主窗体 IsMdiContainer = true;
动态生成的窗体为

cForm=new CForm();   //cForm为CForm类的窗体
			cForm.MdiParent=this;
			cForm.Show();
			this.formList.Add(contractForm); //formList 为一个ArrayList
			cForm.Activated+=new EventHandler(cForm_Activated);

事件

		private void cForm_Activated(object sender, System.EventArgs e)
		{
			//contractForm被激活时产生的事件
			cForm=(CForm) sender;
			MessageBox.Show(cForm.Text+"我被激活了！")
		}

[睡神在睡觉]

谢谢各位了，解决了，一直都是我自己把嵌套关系给搞错了，现在明了了，从TabControl中得到控件要一层一层的拔出来，现在明白了，谢谢各位，明天再顶100分再结贴。
