I was able to get this to work by nesting a repeater that then had a nested repeater on its transformation that had the relationship attributes.
Yes I have DelayedLoading=true. Also had to use
public string ChickasawRelatedForms(object NodeGUID){
repElemForm.WhereCondition = String.Format("NodeGUID = '{0}'", NodeGUID);
return repElemForm.WhereCondition;
}
protected void Page_PreRender(object sender, EventArgs e)
{
repElemForm.ReloadData(true);
}to get the NodeGUID to use in my WhereCondition.
Does that sound like the best solution for this?
