Question

我有这个ultraGrid：

我需要从图片中带红色标记的列传递给摘要单元格一个自定义值。

Infragistics允许我将Max，Min，Sum，Average等放在摘要单元格中，但我需要传递自定义值。

任何帮助？

我有这个代码，它放了Max值：

     Dim columnToSummarizeVlrAq As UltraGridColumn = ugbBens.DisplayLayout.Bands(0).Columns(ugbBensColVlrAq)

 Dim summaryVlrAq As SummarySettings = .Add(ugbBensColVlrAq,SummaryType.Maximum, columnToSummarizeVlrAq, SummaryPosition.UseSummaryPositionColumn)

这里是解决方案：

创建一个新类：

Public Class MyCustomSummarySettings
    Implements ICustomSummaryCalculator

    Private valor As Object = 0

    Public Sub New()
    End Sub

    Public Sub Val()
    End Sub

    Private Sub BeginCustomSummary(ByVal summarySettings As SummarySettings, ByVal rows As RowsCollection) Implements ICustomSummaryCalculator.BeginCustomSummary
        valor = 0
    End Sub

    Private Sub AggregateCustomSummary(ByVal summarySettings As SummarySettings, ByVal row As UltraGridRow) Implements ICustomSummaryCalculator.AggregateCustomSummary

        'Primeiro mês
        If summarySettings.Key = "COL_DeprAntExVlrRv" Then
            If row.Index = 0 Then valor = CDbl(row.Cells("COL_DeprAntExVlrRv").Value)
        End If

        If summarySettings.Key = "fltVlrDepreciavelAct" Then
            If row.Index = 0 Then valor = CDbl(row.Cells("fltVlrDepreciavelAct").Value)
        End If

    End Sub

    Private Function EndCustomSummary(ByVal summarySettings As SummarySettings, ByVal rows As RowsCollection) As Object Implements ICustomSummaryCalculator.EndCustomSummary
        Return valor
    End Function
End Class

并使用摘要类型自定义调用类，如下所示：

Dim custumSummary As New MyCustomSummarySettings

summaryDepreciavel = .Add(ugbBensColDepreciavelAceite, SummaryType.Custom, custumSummary, columnToSummarizeDepreciavel, SummaryPosition.UseSummaryPositionColumn, Nothing) '7ª Coluna

Answer 1

Dim custumSummary As New MyCustomSummarySettings

summaryDepreciavel = .Add(ugbBensColDepreciavelAceite, SummaryType.Custom, custumSummary, columnToSummarizeDepreciavel, SummaryPosition.UseSummaryPositionColumn, Nothing)

Infragistics UltraGrid来自单元格的汇总值
