  • Artikel

Contoh ini menunjukkan gambar teks kustom dalam ComboBox kontrol. Saat item memenuhi kriteria tertentu, item digambar dalam font yang lebih besar dan berubah menjadi merah.

Contoh

Private Sub ComboBox1_MeasureItem(ByVal sender As Object, ByVal e As _
System.Windows.Forms.MeasureItemEventArgs) Handles ComboBox1.MeasureItem
    Dim bFont As New Font("Arial", 8, FontStyle.Bold)
    Dim lFont As New Font("Arial", 12, FontStyle.Bold)
    Dim siText As SizeF

    If ComboBox1.Items().Item(e.Index) = "Two" Then
        siText = e.Graphics.MeasureString(ComboBox1.Items().Item(e.Index), _
lFont)
    Else
        siText = e.Graphics.MeasureString(ComboBox1.Items().Item(e.Index), bFont)
    End If

    e.ItemHeight = siText.Height
    e.ItemWidth = siText.Width
End Sub

Private Sub ComboBox1_DrawItem(ByVal sender As Object, ByVal e As _
System.Windows.Forms.DrawItemEventArgs) Handles ComboBox1.DrawItem
    Dim g As Graphics = e.Graphics
    Dim bFont As New Font("Arial", 8, FontStyle.Bold)
    Dim lFont As New Font("Arial", 12, FontStyle.Bold)

    If ComboBox1.Items().Item(e.Index) = "Two" Then
        g.DrawString(ComboBox1.Items.Item(e.Index), lfont, Brushes.Red, _
e.Bounds.X, e.Bounds.Y)
    Else
        g.DrawString(ComboBox1.Items.Item(e.Index), bFont, Brushes.Black, e.Bounds.X, e.Bounds.Y)
    End If
End Sub
