sort summary child rows

[Felipe Bahiana Almeida]

Hello, I have one syncfusion GridGroupingControl which I have some grouped columns with custom summaries appearing when the groups are collapsed. I am trying to sort the column by both the summary and the child rows.

In order to have the columns sorted by the summary. I used the following code in the routine that handles the event TableControlQueryAllowSortColumn of the control:

' tem coluna agrupando?

            If (Me.TableDescriptor.GroupedColumns.Count > 0) Then

                ' pega a coluna clicada

                _ColunaNomeClicada = e.Column.FieldDescriptor.Name

                ' coluna clicada está no conjunto de colunas sumarizadas?

                If (Me.TableDescriptor.SummaryRows.Count > 0) AndAlso _

                    (Me.TableDescriptor.SummaryRows.Item(0).SummaryColumns.Contains(_ColunaNomeClicada) = True) Then

                    ' pega a coluna sumarizada

                    _ColunaSumarizada = Me.TableDescriptor.SummaryRows.Item(0).SummaryColumns(_ColunaNomeClicada)

                    ' determina o nome da propriedade de sumarizacao

                    ' de acordo com o tipo de sumarizacao

                    Select Case _ColunaSumarizada.SummaryType

                        Case SummaryType.Custom

                            _PropriedadeSumarizacao = "Valor"

                        Case SummaryType.DoubleAggregate

                            _PropriedadeSumarizacao = "Sum"

                        Case Else

                            _PropriedadeSumarizacao = "Sum"

                    End Select ' de acordo com o tipo de sumarizacao

                    ' eh a coluna que esta na ordenacao?

                    If (Me.TableDescriptor.SortedColumns.Count > 0) AndAlso _

                        (Me.TableDescriptor.SortedColumns.Contains(_ColunaSumarizada.Name) = True) Then

                        ' verifica a ordenacao atual

                        If (Me.TableDescriptor.SortedColumns.Item(_ColunaSumarizada.Name).SortDirection = System.ComponentModel.ListSortDirection.Ascending) Then

                            _ColunaDirecaoOrdenacao = System.ComponentModel.ListSortDirection.Descending

                        Else

                            _ColunaDirecaoOrdenacao = System.ComponentModel.ListSortDirection.Ascending

                        End If ' coluna tem uma tag com a ordenacao?

                    End If ' eh a coluna que esta na ordenacao?

                    ' percorre colunas agrupadas

                    For Each _ColunaOrdenacao In Me.TableDescriptor.GroupedColumns

                        ' coloca a ordenacao definida para todos os niveis de agrupamento

                        _ColunaOrdenacao.SetGroupSummarySortOrder( _

                            _ColunaSumarizada.GetSummaryDescriptorName, _

                            _PropriedadeSumarizacao, _

                            _ColunaDirecaoOrdenacao)

                    Next ' percorre colunas agrupadas

it solves the problem of sorting by the summary values but not the children rows. This code is found in many syncfusion samples and forum posts.

Hi Felipe Bahianana almeida,

Thanks for your interest in Syncfusion products.

Query: Sort summary child rows.

To sort the grid from top level to the bottom level you can make use of the following form link which replicates your inquiry. http://www.syncfusion.com/support/forums/grid-windows/43160 If the reported behavior could not be achieved please provide me your essential studio version, and the sample file you have customized. So that I can modify it and provide you.

Please let me know if you have any concerns.

Regards,

Arun.
