大量控件 动态赋值问题

Question

WinForm窗体中有大量TextBox控件，现有一个对象，请问如何将对象中的各个属性赋值给各个TextBox？
注：不是给每个TextBox分别赋值，要一个通用、简便的方法！

Answer 1

for (int i = 0; i < LeaveFormGroupB.Controls.Count; i++)
            {
                if (LeaveFormGroupB.Controls[i] is TextBox)
                {
                    TextBox  temp = (TextBox)LeaveFormGroupB.Controls[i];
                    if (temp.Name == strValue.Trim())
                    {
                        //操作!@
                    }
                    else
                    {
                        temp.Checked = false;
                    }
                }
            }

Answer 2

总有一个属性跟对象的PropertyName对应，一般是控件名，或者Tag属性也可以，另外单独一份mapping表也可以，然后循环控件或循环对象属性，根据mapping关系找出对应的另外一半，然后使用反射读取对象数据，赋值到textbox就可以了

Answer 3

foreach跑Controls集合。
在里面调用GetType看Type是不是TextBox
然后再看Name属性。

TO ：libinguest ，cjcgy
请教一下：1。我有六十多个属性需要显示，我应该如何做？不使用大量的控件的话有什么好的办法吗？
          2。原来我是使用“每个控件赋值”的方法，但发现这样太麻烦，后来使用反射，不过十行代码就解决问题了，请问您这样动态赋值有什么不好的吗？真诚等待您的答案！

string[] Value ={ "1", "2", "3","4" };            for (int i = 0; i < LeaveFormGroupB.Controls.Count; i++)
            {
                if (LeaveFormGroupB.Controls[i] is TextBox)
                {
                    TextBox temp = (TextBox)LeaveFormGroupB.Controls[i];                    temp.Text = Value[LeaveFormGroupB.Controls.Count-i-1];
                                   }
            }

Answer 7

不是有PropertyGrid控件么，专门显示属性的

Answer 8

和这个类似....已解决...简单而明了http://topic.csdn.net/u/20100403/11/9f6de45e-a2cf-4cf9-98ad-65ddbaf92089.html

Answer 9

楼主的意思是否想用绑定呀？可以参考Control.DataBindings 属性。如果需要遍历对象的属性，可以采用反射获取PropertyInfo
