Use a DataView if you just want filtering:

DataTable dtnew = new DataTable();
DataTable dt = (DataTable)XMLSerializerBL.Deserialize(xDocTable.OuterXml, XMLSerializerBL.OutputType.DataTable);
DataView dvData = new DataView(dtData);
dvData.RowFilter = "VKGRP='001'";

grdmy.DataSource = dvData;
grdmy.DataBind();
