Using combo box in c# : <p>I have prepared a program about grocery management. In one place I have to put product category and product brand. Product brands are in one combo box and categories are in another combo box. I want to change the brand combo box according to the text display in category combo box. Eg: if you choose chocolates in category combo box, the brand combo box shows "Mars"," Snickers" and so on. Please help me. I want the c# code for this work. Thank you. I am Sandu.</p>
