Remove relation from Data bound grid

[Alexander Arlievsky]

Hi,
I have to remove the prevously added relation
from data bound grid (at runtime). How it can be done? (Actually I have to replace it by another one) We use sync 1.6

Thank you.

I think you will have to rebind.

this.gridDataBoundGrid1.BeginUpdate();
object o = this.gridDataBoundGrid1.DataSource;
string s = this.gridDataBoundGrid1.DataMember;
            this.gridDataBoundGrid1.Binder.ResetHierarchyLevels();
this.gridDataBoundGrid1.DataMember = "";
this.gridDataBoundGrid1.DataSource = null;
this.gridDataBoundGrid1.DataMember = s;
this.gridDataBoundGrid1.DataSource = o;
GridHierarchyLevel level0 = this.gridDataBoundGrid1.Binder.RootHierarchyLevel;
GridHierarchyLevel level1 = this.gridDataBoundGrid1.Binder.AddRelation("ParentToChild");
this.gridDataBoundGrid1.EndUpdate();
this.gridDataBoundGrid1.Refresh();
