第一题：一个Page:PageA.aspx的网页上放有一个TextBox   ID为TextBox1和一个Button   ID为Button1;
              一个User   Control:UcA.ascx的网页上放有一个Label   ID为Label1。这个UcA.ascx并拉入到PageA.aspx上。
                在TextBox1输入一个值，并按Button1，然把TextBox1的值传至UcA.ascx并显示于Label1。
第二题：一个Page:PageA.aspx的网页上放有一个TextBox   ID   为TextBox1;

在TextBox1输入一个值，并接UcA.ascx上的Button1,然把TextBox1的值传至UcA.ascx并显示于Label1。
第三题：一个User   Control:UcA.ascx的网页上放有一个TextBox   ID为TextBox1;
              一个Page:PageA.aspx的网页上放有一个Button   ID为Button1和一个Label   ID为Label1;
              然后把这个UcA.ascx并拉入到PageA.aspx上。
                在UcA.ascx的TextBox1输入一个值，点PageA.aspx上的Button1，然后把TextBox1的值传至PageA.aspx并显示于       Label1上。
第四题：一个User   Control:UcA.ascx的网页上放有一个TextBox   ID为TextBox1和一个Button   ID为Button1;
              一个Page:PageA.aspx的网页上放有一个Label   ID为Label1;
              然后把这个UcA.ascx拉至PageA.aspx上。
                在UcA.ascx的TextBox1输入一个值，点UCA.ascx上的Button1,然后把TextBox1的值传至PageA.aspx并显示于Label1上。

第五题：一个User   Control:UcA.ascx的网页上放有一个TextBox   ID为TextBox1;
              一个Page:PageA.aspx的网页上放有一个Button   ID为Button1;
              一个User   Control:UcB.ascx的网页上放有一个Label   ID为Label1;
              然后UcA.ascx和UcB.ascx都拉至PageA.aspx上；
                然后在UcA.ascx的TextBox1输入一个值，点PageA.aspx页面上的Button1，把TextBox1的值传至UcB.ascx的Label1上。

第六题：一个User   Control:UcA.ascx的网页上放有一个TextBox   ID为TextBox1和一个Button   ID为Button1;
              一个Page:PageA.aspx；
                一个User   Control:UcB.ascx的网页上放有一个Label   ID为Label1;
