Hierarchical Grid View mix bound and unbound data

[Kind]

hi. 

I have 3 tables that structure showed in attached picture and I want to create the manual hierarchy. for this goal I do this steps  :

1. add column to master and child's template from designer and set "FieldName" property to table file name

2. add GridVew relation from for these master/child template.

3. in the button event click, load tables and set GridView DataSource & child template DataSource from entity framwork:

 using (var entity = new VaccinationEntities())
            {
                radGridView1.DataSource = entity.Patients.ToList();
                childTemplate1.DataSource = entity.ChildVaccinations.ToList();
                childTemplate2.DataSource = entity.ProblemBackgrounds.ToList();
            }

but after load data just master template showed in GridView without child template.

Hello , 

Thank you for writing.  

If you generate the columns manually either at design time or run time, note that it is necessary the FieldName and Name properties of the columns participating in the relation to have equal values. Thus, the hierarchical data will be properly populated. Additional information for binding to hierarchical data programmatically is available in the following help article: http://docs.telerik.com/devtools/winforms/gridview/hierarchical-grid/binding-to-hierarchical-data-programmatically

I hope this information helps. Should you have further questions I would be glad to help.

Regards,
Dess
