How to Find() the object by its property if its changing dynamically

Here is the code which i used:

function DimViewDragFieldToActiveGrid(itemPath)

{

Aliases.QBIS.MainMirandaConsole.Activate();

var PropNames, PropValues,ds;

PropNames = new Array("BackColor.Name","Name");

PropValues = new Array("GradientActiveCaption","WinFormsObject(\"DimensionTableNewUC\")");

var obj = Aliases.QBIS.MainMirandaConsole.MdiClient.Find(PropNames, PropValues, 1000, true);

var grid = obj.WinFormsObject("gridControl");

 var gridTop = grid.ScreenLeft;

 var gridLeft = grid.ScreenTop;

PropNames = new Array("Name","VisibleOnScreen");

  PropValues = new Array("WinFormsObject(\"tvFields\")",true);

  ds = Aliases.QBIS.MainMirandaConsole.MdiClient.Find(PropNames, PropValues, 1000, true);

  ds.ClickItem(itemPath,0);

  var node = ds.SelectedNode;

  var nPnt = ds.WindowToScreen(node.Bounds.X,node.Bounds.Y);

  var dropX = gridLeft - (nPnt.X);

  var dropY = gridTop - (nPnt.Y); 

 ds.Drag(node.Bounds.X+5,node.Bounds.Y+5,dropX,dropY); 

}
