Customization of ComboBoxAdv items
ComboBoxAdv items can be customized by setting DrawMode as OwnerDrawFixed and by handling DrawItem event. You can set the different fore color or back color for ComboBoxAdv items
C#
//Set the draw mode
this.comboBoxAdv1.ListBox.DrawMode = DrawMode.OwnerDrawFixed;
void ListBox_DrawItem(object sender, DrawItemEventArgs e)
{ //Set particular item backcolor e.Graphics.FillRectangle(new SolidBrush(Color.LightBlue), e.Bounds); //Set particular item Text color e.Graphics.DrawString(text, e.Font, new SolidBrush(Color.Purple), e.Bounds);
}
VB
'Set the draw mode Me.comboBoxAdv1.ListBox.DrawMode = DrawMode.OwnerDrawFixed Private Sub ListBox_DrawItem(ByVal sender As Object, ByVal e As DrawItemEventArgs) 'Set particular item backcolor e.Graphics.FillRectangle(New SolidBrush(Color.LightBlue), e.Bounds) 'Set particular item Text color e.Graphics.DrawString(text, e.Font, New SolidBrush(Color.Purple), e.Bounds) End Sub
