[英]Color cells when exporting to Excel from datagridview vb.net
我有基於標准為datagridview中的單元格着色的代碼。 這可以正常工作。
下面顯示的代碼檢查標題“ As(Arsen)”下的值,並將其與為ULxAS定義的定義限制進行比較,並相應地上色。 結果是正確的,並且如上所述。
Private Sub Button6_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button6.Click
'If Not IsNothing(DataGridView2.Rows("As (Arsen)")) Then
'Kategorier i kolonner (vanlig)
'As
Dim UL1As As Double = 8
Dim UL2As As Double = 20
Dim UL3As As Double = 50
Dim Ul4As As Double = 600
Dim Ul5As As Double = 1000
If Me.DataGridView2.CurrentRow.Cells(0).Value Is DBNull.Value Then
MessageBox.Show("Cellen er tom.")
Else
For i As Integer = 0 To Me.DataGridView2.Rows.Count - 1
If Me.DataGridView2.Rows(i).Cells("As (Arsen)").Value < UL1As Then
Me.DataGridView2.Rows(i).Cells("As (Arsen)").Style.BackColor = Color.DodgerBlue
ElseIf Me.DataGridView2.Rows(i).Cells("As (Arsen)").Value >= UL1As And Me.DataGridView2.Rows(i).Cells("As (Arsen)").Value < UL2As Then
Me.DataGridView2.Rows(i).Cells("As (Arsen)").Style.BackColor = Color.LawnGreen
ElseIf Me.DataGridView2.Rows(i).Cells("As (Arsen)").Value >= UL2As And Me.DataGridView2.Rows(i).Cells("As (Arsen)").Value < UL3As Then
Me.DataGridView2.Rows(i).Cells("As (Arsen)").Style.BackColor = Color.Yellow
ElseIf Me.DataGridView2.Rows(i).Cells("As (Arsen)").Value >= UL3As And Me.DataGridView2.Rows(i).Cells("As (Arsen)").Value < Ul4As Then
Me.DataGridView2.Rows(i).Cells("As (Arsen)").Style.BackColor = Color.Orange
ElseIf Me.DataGridView2.Rows(i).Cells("As (Arsen)").Value >= Ul4As And Me.DataGridView2.Rows(i).Cells("As (Arsen)").Value < Ul5As Then
Me.DataGridView2.Rows(i).Cells("As (Arsen)").Style.BackColor = Color.Red
ElseIf Me.DataGridView2.Rows(i).Cells("As (Arsen)").Value >= Ul5As Then
Me.DataGridView2.Rows(i).Cells("As (Arsen)").Style.BackColor = Color.BlueViolet
End If
Next
但是,當我嘗試將相同的邏輯應用於導出例程時,我無法使其正常工作。 我設法導出了顏色跳過第一行但其他顏色正確的輸出。 我可以使它起作用的唯一方法是對列號進行硬編碼。

我希望能夠引用列標題名稱,而不必引用列號,因為它們可能會有所不同,但名稱是不變的。 另外,如果所有行的顏色正確,我也會喜歡的。
任何幫助是極大的贊賞。
在不知道顏色編碼代表什么的情況下,我將這一部分留給您決定。 從發布的圖片看來,顏色不一定表示簡單值,因為相同的值是不同的顏色,具體取決於列。
首先發表你的評論
我設法導出了顏色跳過第一行但其他顏色正確的輸出。
同樣,這是一個簡單的索引問題。 下面的行遍歷DataGridView
的行。
For i As Integer = 1 To DataGridView2.Rows.Count - 1
此循環中的變量i
用作DataGridView
行的索引。 它從零(0)而不是1開始。這將跳過DataGridView
的第一行。 從零開始,它似乎可以正常工作。
其次,我無法使下面的行正常工作。 “ As(Arsen)”部分似乎被忽略了。 我將文本更改為“ Arsen”,它似乎可以正常工作。
DataGridView2.Rows(i).Cells("As (Arsen)").Value
將上面的行更改為:
DataGridView2.Rows(i).Cells("Arsen").Value
進行了這些更改之后,代碼似乎按預期運行了單列“ Arsen”。 由於似乎每列的相同值可能具有不同的顏色,所以我想我缺少了一些東西。 深層的if-then-else語句看起來過於復雜。 下面的代碼改為使用Select / Switch語句。 為了幫助您,將創建一個簡單的Sub來更改給定列的顏色。 這樣,您可以識別列並根據需要更改特定列的顏色。 希望這可以幫助。
在注釋中標記了對原始代碼的更改(更改了一些變量名)
