How to change the color of a cell(back or fore color) of listview item according to item value with if condition.

I do it but it is not work and show no error
Please help me......

What I have tried:

Private Sub btnaddcat_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnaddcat.Click
        For k = 0 To ListView1.Items.Count - 1
            If ListView1.Items(k).SubItems(6).Text > 10000 Then
                ListView1.Items(k).SubItems(6).ForeColor = System.Drawing.Color.Red
            End If
        Next k
    End Sub

推荐答案

您无法按照您尝试的方式比较字符串和整数值。

一种可能的解决方案是在比较之前将字符串值解析为整数：

You cannot compare a string and an integer value the way you tried to.
One possible solution could be to parse the string value to an integer before the comparison:

Dim value As Integer
If Integer.TryParse(ListView1.Items(k).SubItems(6).Text, value) Then
   If value > 10000 Then
      '' ...
   End If
End If
