如何動態更改ListView顏色（跳過一行）

Question

使用VB.Net並嘗試多次實現此目的，但無法使其工作。

我只需要實現以下的一個ListView

dim myRow as string 
 

 
For Each myRow in ListView 
 

 
    ListView1.BackColor = Color.Blue 
 

 
Next

ListView image

ListView1

Answer 1

您可以使用Mod操作符。

Dim myListView As ListView 
    Dim myRow As ListViewItem 
    Dim rowCnt As Integer = 0 
    For Each myRow In myListView.Items 
     If rowCnt Mod 2 = 0 Then 
      myRow.BackColor = Color.Blue 
     Else 
      myRow.BackColor = Color.Gray 
     End If 
     rowCnt = rowCnt + 1 
    Next 

Answer 2

可以使用BackColor屬性ListViewItem。

Dim i As Integer 
For Each lvi As ListViewItem In ListView.Items 
    If i Mod 2 = 0 
     lvi.BackColor = Color.Gold 
    End If 
    i += 1 
Next 

我具有以下示例工作：

ListView1.Items.Add("test1") 
     ListView1.Items.Add("test2") 
     ListView1.Items.Add("test3") 
     ListView1.Items.Add("test4") 

     Dim i As Integer 

     For Each lvi As ListViewItem In ListView1.Items 
      lvi.SubItems.Add("s1") 
      lvi.SubItems.Add("s2") 
     Next 


     For Each lvi As ListViewItem In ListView1.Items 
      If i Mod 2 = 0 Then 
       lvi.BackColor = Color.Gold 
      End If 
      i += 1 
     Next 

我還添加了兩個3列與設計者模式Columns屬性，並設置View屬性等於Details。
