SignUp UR = new SignUp();
DataSet ds = UR.GetAllRegisterations();

// ds.Relations.Add("Cat_Product", ds.Tables["Categories"].Columns["CategoryID"], ds.Tables["Products"].Columns["CategoryID"]);
ds.Relations.Add("Note", ds.Tables["SR"].Columns["SR_ID"], ds.Tables["SE"].Columns["SR_ID"]);

TreeNode tn ;

foreach(DataRow dr in ds.Tables["SR"].Rows)
{
tn = new TreeNode(dr["SR_ID"].ToString());

foreach (DataRow drChild in dr.GetChildRows("SE_ID"))
{

tn.Nodes.Add(drChild["SR_ID"].ToString());

}
treeView1.Nodes.Add(tn);

TreeView1.Nodes.Add(tn);
}
}
