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 ObjectByVal 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.
