Hi ,
   I want to dynamically load an XML file to the Map Control.But I have some problem.
   After I have loaded the XML file using mapObj.LoadXML(),I don't know how to retrive data from my existing DataSet1.
   I have added fields,DataBindingRules,ShapeRules,but the shape labels remain "(No data)".It seems that I have not bind the dataset to the map.
   Would you please help me?Thank you.

Thanks very much.But the text still shows "No data".Here is my code:

string fullPath="D:\\BI Maps\\"+codeParams["ProvName"].ToString()+".xml";
mapObj.LoadXML(fullPath);
Field field=mapObj.ShapeFields.Add("CityName");
field.Type=typeof(string);
field=mapObj.ShapeFields.Add("Amt");
field.Type=typeof(Int32);
mapObj.ShapeFields["CityName"].UniqueIdentifier=true;
mapObj.FieldType=FieldType.Shape;
mapObj.BindingField="CityName";
mapObj.ShapeRules.Add("ShapeRule1");
mapObj.ShapeRules["ShapeRule1"].Text="#AMT";
