foreach (DataRelation rs in dbComm.ds.Relations)
{
    Debug.WriteLine(rs.RelationName);
    Debug.WriteLine(rs.ParentKeyConstraint.ConstraintName);
    Debug.WriteLine(rs.ChildKeyConstraint.ConstraintName);
    foreach (DataColumn col in rs.ChildColumns)
    {
        Debug.WriteLine(col.ColumnName);
    }
    foreach (DataColumn col in rs.ParentColumns)
    {
        Debug.WriteLine(col.ColumnName);
    }
}

for (int i = 0; i < this.ultraGanttView1.Project.Tasks.Count; i++)
{
    if(this.ultraGanttView1.Project.Key == this.ultraGanttView1.Project.Tasks[i].ProjectKey)
    {
        Debug.WriteLine("SAME");
    } else
    {
        Debug.WriteLine("NOT THE SAME");
    }
}

UltraPrintPreviewDialog printPreview = new UltraPrintPreviewDialog();
printPreview.Document = this.ultraGanttViewPrintDocument1;
this.ultraGanttViewPrintDocument1.GanttView = this.ultraGanttView1;
printPreview.ShowDialog(this);//The error comes on this line

Error that I get:

    Hello Robbe,

    Thank you for contacting Infragistics. I have not seen or read any reports of this behavior occurring elsewhere. Which event is this logic handled in?

    You may also want to try swapping lines 28 and 29 before printing.

    eg.
    this.ultraGanttViewPrintDocument1.GanttView = this.ultraGanttView1;
    printPreview.Document = this.ultraGanttViewPrintDocument1;

    I've attached a sample below demonstrating the print preview working with the UltraGantt correctly. Please modify according to your application's specifications and isolate the behavior. I'll review your modifications and investigate this further for you.

    Let me know if you have any questions.
