Step2: Load the data which required to bind into the drop down list1. It has to be called to bind in the page/form load event.
Step3: Write the index changed event to the drop down1 and enable the auto post back event if it is web page.
Step4: Write the logic to get the selected item value in the indexed changed event and get the data from the back end.
Step5: Bind the data into the drop down list 2.
