Oh ok. Then on each selection changed store what you have selected in some kind of list and on each unique selection update that list and check if all are there is that list you can enable that button else disable.

List unilist=new List (); cmb_selectionchanged( object sender System.EventArgs e ) { String str=(sender as ComboBox).SelectedValue.ToString(); //Add that string in unilist if that string is already not present in list //then check all the items are present --if yes ---enable that button --else disable that button }

Sorry. I can get you what do u mean by multiselect? I have three items in my combobox.and selecting each does different job. But i want to enable a button after selecting all items one by one.

You are able to mulitselect in your combox box?? If yes then Write a SelectionChanged Event and there you can check if all items are selected (iterate through loop) then make the button enable else make it disable.
