Thanks Dennis,
It is working now, actually there are two query value in this example. The
first one is the list box selection that select the District 1 until
District 11, and the other is text Box for parcels owner`s name.

I used this line
	---MgLayerBase layer = map.GetLayers().GetItem("Parcels");---

I do check in the SDF table and the value of the NAME Field all in capital
letter so, I type value for query with all capital letter and got the

many thanks
