Question

I want to color all \"Unselectable\" Text from combo box. How can i do this? I tried it but i am unable to do this.

My Code is Given Below:

Answer 1

You need to set the foreground property on the ComboBoxItem to the colour you require.

new ComboBoxItem() { Selectable = false, Text="Unselectable", Value=3, Foreground = Brushes.Red},

Answer 2

You need to set the ComboBox.DrawMode to OwnerDrawxxx and script the DrawItem event e.g. like this:

 private void comboBox1_DrawItem(object sender, DrawItemEventArgs e)
 {

    e.DrawBackground();
     // skip without valid index
    if (e.Index >= 0) 
    {
      ComboBoxItem cbi = (ComboBoxItem)comboBox1.Items[e.Index];
      Graphics g = e.Graphics;
      Brush brush =  new SolidBrush(e.BackColor);
      Brush tBrush = new SolidBrush(cbi.Text == "Unselectable" ? Color.Red : e.ForeColor);

      g.FillRectangle(brush, e.Bounds);
      e.Graphics.DrawString(comboBox1.Items[e.Index].ToString(), e.Font,
                 tBrush, e.Bounds, StringFormat.GenericDefault);
      brush.Dispose();
      tBrush.Dispose();
    }
    e.DrawFocusRectangle();

 }

This part cbi.Text == "Unselectable"is not good, obviously. Since you already have a Property Selectable it should really read !cbi.Selectable". Off course you must make sure that the property is in synch with the text.
