界面上有：
1.一个SqldataSource，它的数据源是"SELECT [ContractNumber], [City], [Road], [Address] FROM [ContractTable]"。
2.一个GridView1，加入了一个选择模块LinkButton_ContractNumber.
3.添加了4个Label，分别是Label_ContractNumber、Label_City、Label_Road、Label_Address。
我要做的效果是点击某一行的“选择”后，鼠标跳到Label_ContractNumber上，并把选中的结果分别显示到4个Label上。
=================问题================
1.鼠标不能跳到Label_ContractNumber上，是不是Label这个控件本身就不支持？
-
2.Label_ContractNumber能正确显示，但其他三个Label只显示“City、Road、 Address”
-
3.在<Columns></Columns>中的数据都有个DataField属性，这个应该就是用来传参数的那个属性吧？比如跳转到下一页会使用
"string myConstractNumber =Request.QueryString["ContractNumber"].ToString();"
而同一个界面传参数听说一般是用 ViewState["args"] = "XXXX";但是我ViewState还没有接触过，正确的应该怎么写呢？？？
