我尝试了几次,以选择下一个重复的行,并同时更改它,
例如
ListBox1项目:
1
1
1
2
1
3
4
5
我的代码(按钮1):
通过将第一行的第一个“ 1”更改为下一个,它将选择 另一个“ 1”,并将其也更改为“更改” ...等等。
If TextBox1.Text = "1" Then
ListBox1.SelectedItem = TextBox1.Text
Dim indx As Integer = ListBox1.SelectedItem
If indx <> -1 Then
ListBox1.Select(indx, TextBox1.Text.Length
If ListBox1.SelectedItem <> "" Then
ListBox1.SelectedIndices = "Changed"
End If
End If
End If
我尝试过此方法,但是它选择了所有重复的项目,并且我希望每个按钮都单击一次。
Dim s As String = Me.TextBox1.Text
Dim lb As ListBox = Me.ListBox1
lb.SelectedIndex = -1
If s.Length <> -1 Then
For i As Integer = 0 To lb.Items.Count - 1
Try
If lb.Items(i).ToString.Contains(s) Then
lb.SelectedIndices.Add(i)
Else
End If
Catch ex As Exception
End Try
Next
End If
每按一次按钮将更改1个重复的项目行。

我不确定我是否了解您的需求,但是请尝试以下操作:
Dim s As String = Me.TextBox1.Text
Dim lb As ListBox = Me.ListBox1
Dim selected = lb.SelectedIndex
If s.Length <> -1 Then
For i As Integer = selected + 1 To lb.Items.Count - 1
If lb.Items(i).ToString = s Then
lb.SelectedIndex = i
Exit For
End If
Next
End If
