private void CreateTree()
{dv = dtTree.DefaultView;
dv.Sort = "TypeParentID ASC"; DataRowView[] arrDRV = dv.FindRows( 0 );//Get root data info
if( arrDRV.Length == 0 ) 
{
return;
}TreeNode tnNew = null;foreach( DataRowView drv in arrDRV )
{ tnNew = TreeView.Nodes.Add( drv.Row["TypeName"].ToString() );
tnNew.Tag = drv.Row["TypeID"].ToString();//Save "TypeID" in node's tag CreateTreeNode( ref tnNew );
}this.TreeView.ExpandAll();
}private void CreateTreeNode( ref TreeNode tnParent )
{DataRowView[] arrDRV = dv.FindRows( tnParent.Tag );//Get children data infoif( arrDRV.Length == 0 )
{
return;
}TreeNode tnNew = null;foreach( DataRowView drv in arrDRV )
{
tnNew = tnParent.Nodes.Add( drv.Row["TypeName"].ToString() );
