CustomerView

 

In my CustomerView I have Field called Area and near to area i have created one add button. suppose i enter the customer details and select the area the area is not in the dropdown list . so i need to add the area . so i click the add button . it redirect to the area Partial view  from Customer  view. I had create one Area Partial VIew for the Area field.

 

 Area Partial view

 

 

 

if i click the add button near to Area it redirect to Area PartialView (LocalHost/Customer/AreaPartialView). In Area Partial view i  enter the values and click the Create button it  save the data in DB and also it redirect to same customer view . Now My Issue is  I enter the CustomerName ,Street,Location, Place, Alias and then only i select the area . Now the area is not listed in the Dropdown means i need to add it so i click that add button near to area. it redirect to area Partial view and i enter the values and click the create button. When i click the create button from area Partial view it redirect to Same Customer view at the  same time page get reloaded. so my data all are lost which i enter in the CustomerName ,Street,Location, Place, Alias, so i have to enter the details again . This is my issue .  I don't want to page gets reloaded when it redirect from Partial view to CutomerView  that is if i click add button from Customer View it redirect to Area Partial view . In Area Partial View  enter the value and  if i click the create button it again redirect to customer view . In this stage the page gets reloaded . Because of reloading the data which is enterd in the customer view too get refreshed and lost. so please any tell me how to stop this page reloading when the button is clicked in mvc4
