Child and Parent datagrid problem!

[Sep410]

Hi all,

Here is my code:

da1.Fill(ds, "Parent")
da2.Fill(ds, "Child")
Dim DataRelation As New DataRelation("Family", ds.Tables("Parent").Columns("CaseID"), ds.Tables("Child").Columns("CaseID"), False)
ds.Relations.Add(DataRelation)
Dim dv As New DataView(ds.Tables("Parent"))
PublicDS = ds

dgSearch.DataSource = dv

'-----------datagrid
Try
dts1.MappingName = "Parent"
dgSearch.TableStyles.Add(dts1)
dgSearch.TableStyles(0).GridColumnStyles(0).Width( ) = 0
dgSearch.TableStyles(0).GridColumnStyles(4).Width( ) = 0
Catch ex As Exception

End Try

The problem is I will see the relation’s name(Family) when I click at the + beside parent name and I should click on that name and then I can see the child.
I need to see child when I click on +.

Please help me.
