[RESOLVED] Change Listview Backcolor with a condition

[killer7k]

Hello ,

i'am trying to make unique backcolor for every listview row
i have some legend 3 with color
Salary > 6000 = Listview row will be blue
Salary > 8000 = Listview row will be pink
Salary > 6000 = Listview row will be green

actually i have 7 column in my Listview
the salary column approrpiate is number 4

what i'am trying to do is :

   If (lvItem.SubItems(4).Text >6000) Then
                 lvItem.BackColor = Color.CornflowerBlue
                    lvItem.SubItems(1).BackColor = Color.CornflowerBlue
                    lvItem.SubItems(2).BackColor = Color.CornflowerBlue
                    lvItem.SubItems(3).BackColor = Color.CornflowerBlue
                    lvItem.SubItems(4).BackColor = Color.CornflowerBlue
                    lvItem.SubItems(5).BackColor = Color.CornflowerBlue
                    lvItem.SubItems(6).BackColor = Color.CornflowerBlue
                    lvItem.SubItems(7).BackColor = Color.CornflowerBlue
                   
                   End If

....

but not work

Thanks

I, instead, would create a unique ListViewItem per object. In this case, you'd make three:

Salary > 6000 = lviBlue
Salary > 8000 = lviPink
Salary > 10000 = lviGreen

Example Usage:

Dim lviBlue As ListViewItem = New ListViewItem
        lviBlue.Text = "Blue"
        lviBlue.SubItems.Add("6,000")
        lviBlue.BackColor = Color.Blue
        ListView1.Items.Add(lviBlue)
 
        Dim lviPink As ListViewItem = New ListViewItem
        lviPink.Text = "Pink"
        lviPink.SubItems.Add("8,000")
        lviPink.BackColor = Color.Pink
        ListView1.Items.Add(lviPink)
 
        Dim lviGreen As ListViewItem = New ListViewItem
        lviGreen.Text = "Green"
        lviGreen.SubItems.Add("10,000")
        lviGreen.BackColor = Color.Green
        ListView1.Items.Add(lviGreen)

I might be misunderstanding what you're asking for and I, of course, don't know how the rest of your is, so this is my best example usage.

Also, there might be a better way, but this is what I came up with.

First up, the default value for the UseItemStyleForSubItems property of a ListViewItem is True so, unless you want to use different Fonts or ForeColors for the subitems, you only have to set the item BackColor, not all the subitems too.

Secondly, if you test for greater than 6000 first then everything greater than 8000 and whatever else (you have 6000 twice in your post above) will match too, which you don't want.

Dim backColor As Color
 
Select Case CInt(lvItem.SubItems(4))
    Case Is > 9000
        backColor = Color.Green
    Case Is > 8000
        backColor = Color.Pink
    Case Is > 6000
        backColor = Color.CornflowerBlue
    Case Else
        backColor = SystemColors.Window
End Select
 
lvItem.BackColor = backColor

Thanks John ,

actually there is bug
i modded that code but

                    Select Case CInt(item1.SubItems(4).Text)

                        Case Is > 9000

                        backColor = Color.Green

                        Case Is > 8000

                            backColor = Color.Pink

                        Case Is > 6000

                            backColor = Color.Green

                        Case Else

                            backColor = SystemColors.CornflowerBlue

                    End Select



                    ListView3.BackColor = backColor

actually i'am show listview rows via loop
when i added that code i get the the backcolor changed on the Listview itself
but i'am trying to change backcolor of current row in the listview
