【中文标题】使用 columns 键和为每个更改超网格中的单元格颜色【英文标题】:Changing the cell color in an ultragrid with the columns key and for each 【发布时间】:2021-12-17 16:16:00 【问题描述】:我的目标是为我已经着色的完全相同的单元格着色,但之前只有一列。我试着用索引来做,但没有成功。我得到一个提示,我应该用 Key 属性来做,但我不知道怎么做。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
感谢您对 c# 和 vb.net 的任何帮助。谢谢

【参考方案1】: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

【参考方案2】:我认为这会奏效:
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
【讨论】:
不,它没有。它将整个列着色为两个索引。【参考方案3】:您应该像这样将单元格的值与DbNull.Value
进行比较:
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
【讨论】:
为什么? if 语句工作正常,问题是 (column.Index - 1) 不起作用 回答为什么 (column.Index - 1) 我们需要知道您的列的结构。顺便说一句,您是否使用 (column.Index) 而不是 (column.Key) 对此进行了测试? 是的,我做到了。我找到了解决方案,我会在这里发布。以上是关于使用 columns 键和为每个更改超网格中的单元格颜色的主要内容,如果未能解决你的问题,请参考以下文章
