Hello:
Two quick questions. Do the DataFieldID and DataFieldParentID have to be numeric (like an integer data type)? It doesn't seem to work if I have those fields as strings. I'm trying to generate an org chart, using a string-based employee ID, but it comes up blank.
Second, to make it work, I converted the ID to an integer for the two fields. It then works fine, but I noticed that I have to set the "root" item to have a "0" for the parent field. Is this expected? As an example, I want to generate an Org with me at the top. In the dataset, the row that represents me has a parent employee ID, but that employee ID is not present in the data since I don't want my supervisor displayed. In order to get the chart to render, I have to look through the records and ensure that my record as "0" for the parent.
Perhaps this second issue is related to the first. If a string is in fact supported, does the top level item need to have the parent field set to a particular value? Perhaps an empty string?
Thanks,
Chris

Hi Chris,
It is not a problem if the ParentID is string. The problem is that the first node in the hierarchy shouldn't have a ParentID - it should be null. If the ParentID of the first node is set, it means that it has a parent. So, it leads to an empty hierarchy.
All the best,
