Hi Supriya,

Thank you for your interest in Syncfusion products.

If you want to set the ReadOnly property to the ParentRecords(i.e. Records which has Plus/Minus), you can use QueryCellStyleInfo event. Please make use of below code,

Code Snippet:

Private Sub gridGroupingControl1_QueryCellStyleInfo(ByVal sender As Object, ByVal e As GridTableCellStyleInfoEventArgs)
        Dim rec As Record = e.TableCellIdentity.DisplayElement.GetRecord
        If ((Not (rec) Is Nothing)  _
                    AndAlso (rec.HasNestedTables  _
                    AndAlso ((e.TableCellIdentity.TableCellType <> GridTableCellType.EmptyCell)  _
                    AndAlso ((e.TableCellIdentity.TableCellType <> GridTableCellType.NestedTableIndentCell)  _
                    AndAlso (e.TableCellIdentity.TableCellType <> GridTableCellType.NestedTableRowHeaderCell))))) Then
            e.Style.ReadOnly = true
        End If
    End Sub

Please let me know if you have any concerns.
