Answer 4

方便你看  去掉了一些 html

Answer 5

control = (控件類型)e.Item.FindControl(控件ID);

Answer 6

哦!抱歉!!没太注意!!
1.首先设置行号,也即Button的CommandArgument:
    protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        ((Button)e.Item.FindControl("Button1")).CommandArgument = e.Item.ItemIndex.ToString();
    }2.设置在Repeat中Button的click事件,也即:
......
<asp:Button ID="Button1" runat="server" Text="Button"  OnClick="Button1_Click"/>
...........3.
    protected void Button1_Click(object sender, EventArgs e)
    {
        Button myButton = (Button)sender;
        int index = Convert.ToInt16(myButton.CommandArgument);//获得点击的行号
        string a1 = ((Label)Repeater1.Items[index].FindControl("名称1")).Text;
        string a2 = ((Label)Repeater1.Items[index].FindControl("名称2")).Text;
   }
看一下html代码,必定有控件名称!!

Answer 8

  string a1 = ((Label)Repeater1.Items[index].FindControl("名称1")).Text; 
        string a2 = ((Label)Repeater1.Items[index].FindControl("名称2")).Text; 

Answer 9

不用控件的名称也可以,但你要测试究竟是多少数字??
        string a1 = ((Label)Repeater1.Items[index].Controls[1]).Text;
        string a2 = ((Label)Repeater1.Items[index].Controls[3]).Text;
        string a3 = ((Label)Repeater1.Items[index].Controls[5]).Text;这个1,3,5要通过测试来确定,究竟排在第几位!!

Answer 10

估计楼主也没有用Label吧。加上Label好方便点。。
