In the following code assume you want to disable the second item in your combobox item list. // Disbaling the color of the item number-2 Font myFont = new Font ( Aerial  10  FontStyle . Regular ); private void comboBox1_DrawItem ( object sender  DrawItemEventArgs e ) { if ( e . Index == 1 ) //We are disabling item based on Index you can have your logic here { e . Graphics . DrawString ( comboBox1 . Items [ e . Index ]. ToString () myFont  Brushes . LightGray  e . Bounds ); } else { e . DrawBackground (); e . Graphics . DrawString ( comboBox1 . Items [ e . Index ]. ToString () myFont  Brushes . Black  e . Bounds ); e . DrawFocusRectangle (); } } // Diabling the action for the item number-2 void comboBox1_SelectedIndexChanged ( object sender  EventArgs e ) { if ( comboBox1 . SelectedIndex == 1 ) comboBox1 . SelectedIndex = - 1 ; }

One more thing to get above functionality working you need to set 'DrawMode' on your combobox to 'OwnerDrawFixed'. if it helps you please mark the answer accepted
