本文介绍如何在ASP.NET中使用GridView嵌套Repeater控件来展示分级数据，并提供具体的代码实现，包括数据绑定及从这些控件中获取数据的方法。

GridView 中嵌套 Repeater ，显示分级数据：

在 GridView1 的 GridView1_DataBound 事件中这样写：

protected void GridView1_DataBound(object sender, EventArgs e)
    {
        foreach (GridViewRow row in GridView1.Rows)
        {
            Label LabelID = row.FindControl("Label1") as Label;
            string parentID = LabelID.Text.ToString();
            Repeater subRepeater = row.FindControl("Repeater1") as Repeater;
            string sql = "select * from CandidateUser where WantPosition = '"+parentID+"' order by UID asc";
            DataSet ds = newdb.CommonDataSet(sql);
            subRepeater.DataSource = ds.Tables[0].DefaultView;
            subRepeater.DataBind();

        }

    }

然后，当点击按钮，提交此页面,需要循环 GridView1 和 Repeater1 中的数据取值，存入数据库，如何取值呢，这样做：

protected void Button1_Click(object sender, EventArgs e)
{
  foreach (GridViewRow row in GridView1.Rows)
        {
            Label LabelID = row.FindControl("Label1") as Label; //竞聘职位的ID号Label
            parentID = LabelID.Text.ToString();//竞聘职位的ID号

            Repeater subRepeater = row.FindControl("Repeater1") as Repeater;

            foreach (RepeaterItem subrow in subRepeater.Items)
            {
                Label LabelUserID = subrow.FindControl("Label2") as Label;  //竞聘人的身份ID号Label
                CandidateUserID = LabelUserID.Text.ToString();//竞聘人的身份ID号

                TextBox txbScore = subrow.FindControl("TextBox1") as TextBox;  //分数 TextBox1
                CandidateScore = txbScore.Text.ToString();//分数

                CheckBox ckbGiveUp = subrow.FindControl("CheckBox1") as CheckBox;  //分数 TextBox1
                if (ckbGiveUp.Checked == true)
                {
                    giveup = "1";
                }
                else
                {
                    giveup = "0";
                }

                sql = "insert into VoteTable (PositionID,CandidateUserID,CandidateUserScore,GiveUpVote,WhoSendTheVote) values ('" + parentID + "','" + CandidateUserID + "','" + CandidateScore + "','" + giveup + "','" + getName + "')";
                newdb.ModifyData(sql);

            }

        }

}
