使用列键和每个更改超网格中的单元格颜色

Question

我的目标是为与我已经着色的完全相同的单元格着色，但只是之前的一列。我试着用索引来做，但没有成功。我得到一个提示，我应该使用 Key 属性来完成它，但我不知道该怎么做。这是我尝试过的：

For Each column As UltraGridColumn In ugResult.DisplayLayout.Bands(0).Columns

                If column.Key = "K_Art" Or column.Key = "UANR" Or column.Key = "Ueberbegriff" Or column.Key = "Benennung" Or column.Key = "Anzahl" Or column.Key = "Einheit" Or column.Key = "Einzelkosten" Or column.Key = "Sumcode" Or column.Key = "Status" Then
                    Exit For
                Else
                    If e.Row.Cells(column.Key).Value IsNot Nothing Then

                        e.Row.Cells(column.Key).Appearance.BackColor = Color.Yellow
                        e.Row.Cells(column.Index - 1).Appearance.BackColor = Color.Yellow
                    End If

                End If
            Next

对 c# 和 vb.net 的任何帮助表示赞赏。谢谢

Answer 1

我认为这会起作用：

For Each column As UltraGridColumn In ugResult.DisplayLayout.Bands(0).Columns
     If column.Key = "K_Art" Or column.Key = "UANR" Or column.Key = "Ueberbegriff" Or column.Key = "Benennung" Or column.Key = "Anzahl" Or column.Key = "Einheit" Or column.Key = "Einzelkosten" Or column.Key = "Sumcode" Or column.Key = "Status" Then
           Exit For
     Else
           If e.Row.Cells(column.Key).Value IsNot Nothing Then
                e.Row.Cells(column.Index).Appearance.BackColor = Color.Yellow
                e.Row.Cells(column.Index - 1).Appearance.BackColor = Color.Yellow
         End If
     End If
Next

Answer 2

您应该将单元格的值与 DbNull.Value 进行比较，如下所示：

For Each column As UltraGridColumn In ugResult.DisplayLayout.Bands(0).Columns
    If column.Key = "K_Art" Or column.Key = "UANR" Or column.Key = "Ueberbegriff" Or column.Key = "Benennung" Or column.Key = "Anzahl" Or column.Key = "Einheit" Or column.Key = "Einzelkosten" Or column.Key = "Sumcode" Or column.Key = "Status" Then
        Exit For
    Else
        If Not DbNull.Value.Equals(e.Row.Cells(column.Key).Value) Then
            e.Row.Cells(column.Key).Appearance.BackColor = Color.Yellow
            e.Row.Cells(column.Index - 1).Appearance.BackColor = Color.Yellow
        End If
    End If
Next

Answer 3

这是我的解决方案：

For Each column As UltraGridColumn In ugResult.DisplayLayout.Bands(0).Columns
                Select Case column.Key
                    Case "K_ArtCompare"
                        If e.Row.Cells(column.Key).Value IsNot Nothing Then
                            e.Row.Cells(column.Key).Appearance.BackColor = Color.Yellow
                            e.Row.Cells("K_Art").Appearance.BackColor = Color.Yellow
                        Else
                            e.Row.Cells(column.Key).Value = e.Row.Cells("K_Art").Value
                        End If
                    Case "UANR_Compare"
                        If e.Row.Cells(column.Key).Value IsNot Nothing Then
                            e.Row.Cells(column.Key).Appearance.BackColor = Color.Yellow
                            e.Row.Cells("UANR").Appearance.BackColor = Color.Yellow
                        Else
                            e.Row.Cells(column.Key).Value = e.Row.Cells("UANR").Value
                        End If
                    Case "UeberbegriffCompare"
                        If e.Row.Cells(column.Key).Value IsNot Nothing Then
                            e.Row.Cells(column.Key).Appearance.BackColor = Color.Yellow
                            e.Row.Cells("Ueberbegriff").Appearance.BackColor = Color.Yellow
                        Else
                            e.Row.Cells(column.Key).Value = e.Row.Cells("Ueberbegriff").Value
                        End If
                    Case "BenennungCompare"
                        If e.Row.Cells(column.Key).Value IsNot Nothing Then
                            e.Row.Cells(column.Key).Appearance.BackColor = Color.Yellow
                            e.Row.Cells("Benennung").Appearance.BackColor = Color.Yellow
                        Else
                            e.Row.Cells(column.Key).Value = e.Row.Cells("Benennung").Value
                        End If
                    Case "AnzahlCompare"
                        If e.Row.Cells(column.Key).Value <> -1 Then
                            e.Row.Cells(column.Key).Appearance.BackColor = Color.Yellow
                            e.Row.Cells("Anzahl").Appearance.BackColor = Color.Yellow
                        Else
                            e.Row.Cells(column.Key).Value = e.Row.Cells("Anzahl").Value
                        End If
                    Case "EinheitCompare"
                        If e.Row.Cells(column.Key).Value IsNot Nothing Then
                            e.Row.Cells(column.Key).Appearance.BackColor = Color.Yellow
                            e.Row.Cells("Einheit").Appearance.BackColor = Color.Yellow
                        End If
                    Case "EinzelkostenCompare"
                        If e.Row.Cells(column.Key).Value <> -1 Then
                            e.Row.Cells(column.Key).Appearance.BackColor = Color.Yellow
                            e.Row.Cells("Einzelkosten").Appearance.BackColor = Color.Yellow
                        Else
                            e.Row.Cells(column.Key).Value = e.Row.Cells("Einzelkosten").Value
                        End If
                    Case "SummencodeCompare"
                        If e.Row.Cells(column.Key).Value IsNot Nothing Then
                            e.Row.Cells(column.Key).Appearance.BackColor = Color.Yellow
                            e.Row.Cells("Sumcode").Appearance.BackColor = Color.Yellow
                        Else
                            e.Row.Cells(column.Key).Value = e.Row.Cells("Sumcode").Value
                        End If
                End Select

            Next
    End Select
