Hi Guys need help.

I created a listview with 2 column.
Name and Score

I need to change the color of those scores below 85% below is my code that i found in google but its not working properly

VB

    Private Sub ListView1_DrawColumnHeader(ByVal sender As Object, ByVal e As System.Windows.Forms.DrawListViewColumnHeaderEventArgs) Handles ListView1.DrawColumnHeader
        e.DrawDefault = True
    End Sub

    Private Sub ListView1_DrawItem(ByVal sender As Object, ByVal e As System.Windows.Forms.DrawListViewItemEventArgs) Handles ListView1.DrawItem
        Dim ColIndex As Integer = 6
        e.Item.UseItemStyleForSubItems = False

        Dim si As ListViewItem.ListViewSubItem = e.Item.SubItems(2)
' textbox1.text has a value of 85%
        If si.Text > Me.TextBox1.Text Then
            si.ForeColor = Color.Black
        Else

I don't think you can compare text with the > operator.

2 solutions

Solution 1

I change my code to:

VB

For Each lvi As ListViewItem In Me.ListView1.Items
      Dim va As String = 89%
      If lvi.SubItems(2).Text < va Then

          lvi.UseItemStyleForSubItems = False
          lvi.SubItems(2).ForeColor = Color.red
      End If

  Next

However everytime I get 100% the value still change to red :(

still, like Richard MacCutchan sayed.. you can't use < or > operators on Strings in this way..
you need your current % value and your 89% as some numeric Type.... than

dim yourListviewValue as integer = 73
if yourListviewValue < 89 then 'this will work.

Maybe it is time to go back to the documentation and learn the rules of VB.NET.

I actually changed the color of the value less that 89% however if the value is 100% it also changed the color :(

Have you tried removing the percentage and converting both the values to double or integer and the compare it and change the color.

Hope this helps.
