How to make the Relation of hierarchical webgrid for 3 layes.

I have 3 tables in my dataset and i wrote relation like this.

 

dsMeetExp.Relations.Add(dsMeetExp.Tables[

 

"GetMeetingExpenceByDiv"].Columns[0], dsMeetExp.Tables["GetMeetingExpenceByDiv1"].Columns[0]);

// Define relation for to get tree structure in webgrid.

dsMeetExp.Relations.Add(dsMeetExp.Tables[

 

"GetMeetingExpenceByDiv1"].Columns[2], dsMeetExp.Tables["GetMeetingExpenceByDiv2"

].Columns[2]);

BUt i got "This constraint cannot be enabled as not all values have corresponding parent values." exception

Please help me to resolve this.
