TcxDBTreeList - Changing a node's parent field value to a value that does not correspond to any existing node via dataset members posts this node

created 12 years ago

Hi everybody,

I have a problem when editing the parentID in the cxDBTreelist

When I change the record of the node from a level to another level … no problem if the level towards I will put the node is not the root.

This code works properly …

cxDBTreeList1.DataController.DataSet.Edit;
cxDBTreeList1.DataController.DataSet.FieldByName('idparent').asinteger := 2;
cxDBTreeList1.DataController.DataSet.Post

but the following code don't work … if i want to put the node at the root level

cxDBTreeList1.DataController.DataSet.Edit;
cxDBTreeList1.DataController.DataSet.FieldByName('idparent').Clear;
cxDBTreeList1.DataController.DataSet.Post

the error message … 'DATASET not in edit or insert mode'
When debugging, just after the clear, the state of the dataset is dsBrowse !!!
And after that if I want to made other changes, I have the same error message on any node I will change.

Do you have any idea ?
Thanks for your help.
