    copied!<p>If you perform single inserts, you can check for bad relatives at the time of the insert. You can than copy the bad data to a new table.</p> <p>In this example I have defined a typed dataset called "dsBadRowTest" Which contains a table called "ParentTable" with the column "PrimaryKeyColumn". It is the parent table of another table called "ChildTable" on it's "ForeignKeyColumn". I define a relational dataset and then attempt to add invalid children. For each invalid child, I store the column information in a separate table variable.</p> <pre><code>//Our relational dataset... dsBadRowTest dsRelated = new dsBadRowTest(); //The error table will be a non-relational version dsBadRowTest.ChildTableDataTable dtErrors = new dsBadRowTest.ChildTableDataTable(); //Add an extra column the error table for extra info dtErrors.Columns.Add("ErrorMessage"); //Fill our parent table for (Int32 i = 1; i &lt;= 5; i++) { dsRelated.ParentTable.AddParentTableRow(i); } //attempt to fill our child table, with invalid children for (Int32 i = 1; i &lt;= 10; i++) { dsBadRowTest.ChildTableRow drNewChild = dsRelated.ChildTable.NewChildTableRow; drNewChild.ForeignKeyColumn = i; try { dsRelated.ChildTable.AddChildTableRow(drNewChild); } catch (Data.InvalidConstraintException ex) { //Problem adding...Copy the row for the error table dsBadRowTest.ChildTableRow drError = dtErrors.NewChildTableRow; foreach (System.Data.DataColumn dc in drNewChild.Table.Columns) { drError(dc.ColumnName) = drNewChild(dc); } //Our non-typed extra column will contain the error message drError("ErrorMessage") = ex.Message; dtErrors.AddChildTableRow(drError); } } if (dtErrors.Rows.Count &gt; 0) { //Uh oh, we had some bad inserts //...do something with the list of errors... } </code></pre> <p>You can keep the relations in place and check for specific exceptions as they are throw.</p> <p>(Here is the typed dataset I used for this sample...
