If you return query results to a GraphicsLayer, you can use this GraphicsLayer to set FeatureDataGrid.GraphicsLayer property. Very similar to this sample except you will be using the GraphicsLayer that contain your query results. http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#ToolkitFeatureDataGrid

If your DataGrid contain GraphicCollection as its ItemsSource, you can use SelectionChanged event to get the selected row (which is a graphic) and call Map.ZoomTo(graphic.Geometry).

You can use string.Format() http://msdn.microsoft.com/en-us/library/system.string.format(v=VS.95).aspx
query.Where = string.Format("FEILD1 like '%{0}%' and FEILD2='TOWN BORDER STATION'", Textbox1.Text.Trim());
