Good-day,

I have a dataset containing two tables, in a Master-Detail type relationship.  I would like to insert a new row into the child table, but I'm receiving an error "ForeignKeyConstraint RelTables requires the child key values (There) to exist in the parent table".

Here is my code:

******************************************
//DataSet ds
DataRelation relate;
relate = new DataRelation("RelTables", ds.Tables["Parent"].Columns["Col1"], ds.Tables["Child"].Columns["Col1"]);
ds.Relations.Add(relate);

DataRow dr;
dr = Form1.DVM.DataSet.Tables["Child"].NewRow();
dr["Col1"] = "Hello";
dr["Col2"] = "World";

ds.Tables["Child"].Rows.Add(dr);
******************************************

Any suggestions would be appreciated,
Thanks for your time.

You have set a relation between "Col1" of parent table and of child table
And you are trying to set the value "Hello" in Child Col1 table
Are you sure that this value "Hello" exist in the Col1 of parent table ?
