My pc environment:VS2008+MS SqlServer2000+infragistics 8.1 

In old version (before 8.1),I usually do like this:

  (1) add an other sqlDatasource, and set column 's property "type"-->"Dropdownlist" ,"valueList"-->"DatasourcID" set the new sqldatasource then set value/data propery.

   But now the DatasourceID - list doesn't work! I can't see any sqlDatasource in WebForm. when I set this mannuly,Error message:sqldatasource2 only support viewmap?...

(2) add a webcombo,set column's "Type"-->"Custom",EditControlID-->the WebCombo. but the editcontrolID 's list can't find anything...

Help me,please!
