Title: Make a ComboBox display images or icons with text in vb.net
Post by: samideqlqpart on August 31, 2016, 04:41:21 PM

 hello everybody

my problem is how to make a ComboBox that displays either a series of color samples or a list of images
or how to make a ComboBox that displays a series of images with associated text.

i've made one but
icons in my combobox are not like i want
here is my code and result

Private Sub ComboBox1_DrawItem(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles ComboBox1.DrawItem

        If (e.Index <> -1) Then

            e.Graphics.DrawImage(ImageList1.Images(e.Index), e.Bounds.Left, e.Bounds.Top)

            e.Graphics.DrawString(Me.ComboBox1.Items(e.Index).ToString(), e.Font, System.Drawing.Brushes.Black, e.Bounds.Left + ImageList1.Images(e.Index).Width, e.Bounds.Top)
           
        End If

    End Sub

thank you

I would think an imageList control should handle this.

Or, just use listview:

Code - C#: [Select]

1. listView1.View = View.Details; // Enables Details view so you can see columns
2. listView1.Items.Add(new ListViewItem { ImageIndex = 0, Text = "Image 1" });
3.

Syncfusion has a free set of controls for individuals and small businesses.   I do not use the controls personally but they do have a combobox that looks like it might work for what you want.

So it seems as though you now have some options, as MexicanCustard suggested, WPF is your best solution even if learning how is a bit harder than WinForms, you get a lot more control of the appearance of your forms.

Whatever you choose, give it a go and if you get stuck I'm sure we can give you more specific help once you have some code to review.
cheers.

I couldn't get imagelist to work correctly either except on small 16x16 icons.

Just to show how simple this would be using WPF.

Code: [Select]

<Window>
    <Window.Resources>
        <DataTemplate DataType="{x:Type MyClass}">
            < StackPanel Orientation="Horizontal">
                <Image Source="{Binding Image}" Width="20" Height="20"/>
                <TextBlock Text="{Binding Text}"/>
            </StackPanel>
        </DataTemplate>
    </Window.Resources>
    <Grid>
        <ListBox ItemsSource="{Binding MyList}"/>
    </Grid>
</Window>
