Answer 2

eg:
TreeView1.Nodes[0].Nodes.Clear();
for(int i=1;i<=dv.Count;i++)
{
TreeView1.Nodes[0].Nodes.Add(new Microsoft.Web.UI.WebControls.TreeNode());
TreeView1.Nodes[0].Nodes[i-1].Text= dv[i-1]["jhmc"].ToString().Trim();
TreeView1.Nodes[0].Nodes[i-1].Type = dv[i-1]["jhbm"].ToString().Trim();
TreeView1.Nodes[0].Nodes[i-1].ImageUrl="./images/jh.gif";
//点击第二层
ls_SqlStr = "select distinct bzbh,bzmc from xlxjt_gtjh where bzmc is not null and jhbm='" + dv[i-1]["jhbm"].ToString().Trim() +"'" ;
db.Open();
DataSet dataset1=db.exeSqlForDataSet(ls_SqlStr);
db.Close();

DataView Dv1=dataset1.Tables[0].DefaultView;
if (Dv1.Count>0)
{
TreeView1.Nodes[0].Nodes[i-1].Nodes.Clear();
for (int t=0;t<=Dv1.Count-1;t++)
{
TreeView1.Nodes[0].Nodes[i-1].Nodes.Add(new Microsoft.Web.UI.WebControls.TreeNode());
TreeView1.Nodes[0].Nodes[i-1].Nodes[t].Text=Dv1[t]["bzmc"].ToString();
                        TreeView1.Nodes[0].Nodes[i-1].Nodes[t].Type= Dv1[t]["bzbh"].ToString();
TreeView1.Nodes[0].Nodes[i-1].Nodes[t].ImageUrl="./images/bzjh.GIF";
} }
}

{
        oleDbDataAdapter1.Fill(dataSet11.book_sort1_inf );
        oleDbDataAdapter2.Fill(dataSet11.book_sort2_inf );
        oleDbDataAdapter3.Fill(dataSet11.book_sort3_inf );
        oleDbDataAdapter4.Fill(dataSet11.book_inf );
try
{   
               oleDbConnection1.Close();
              oleDbConnection1.Open();
for (int i=0;i<dataSet11.book_sort1_inf.Count;i++)
{
System.Windows.Forms.TreeNode n1,n2,n3;
n1=new TreeNode(dataSet11.book_sort1_inf.Rows[i][1].ToString());   
for (int j=0;j<dataSet11.book_sort2_inf.Count;j++)
{  
if  (dataSet11.book_sort1_inf.Rows[i][0].ToString()==dataSet11.book_sort2_inf.Rows[j][1].ToString())
{
n2=new TreeNode(dataSet11.book_sort2_inf.Rows[j][2].ToString()); 
 n1.Nodes.Add(n2);
                            
for (int k=0;k<dataSet11.book_sort3_inf.Count;k++)
{
if  (dataSet11.book_sort2_inf.Rows[j][0].ToString()==dataSet11.book_sort3_inf.Rows[k][1].ToString())
                                    
{
n3=new TreeNode(dataSet11.book_sort3_inf.Rows[k][2].ToString());
n2.Nodes.Add(n3);

}
}
                              }
}
                          
                     


this.treeView1.Nodes.Add(n1);  
}     }
finally
{


}
  }你可以参考一下。。
