  1. You can disable/enable the combobox, on the basis of button click
  2. You can unsubscribe the SelectedIndexChanged as told by @Ramashankar
  3. Maintain a flag to check whether event has to be executed or not

ComboBox comboBox = new  ComboBox();

Subscribe to SelectedIndexChanged event

comboBox.SelectedIndexChanged += comboBox_SelectedIndexChanged;

Use below code to unsubscribe the SelectedIndexChanged event

comboBox.SelectedIndexChanged -= comboBox_SelectedIndexChanged;
