MVC Core Web Application

Question

I have one Dropdown List and one TextBox control in my View. The Dropdown list contains branch codes and when i select the branch code i want to display its associated branch name in the TextBox control. I created the following action Method:

 

public string RerieveBranchName(string id)

{

var branchName = from e in dbContext.CompanyBranches

                               where e.BranchCode == id

                               select e;

ViewBag.SelectedBranchID = branchName.ToString();

return "0"; 

}

 

 Now my problem is how to pass the branch id to the action method when i select it from the dropdown list and after passing the branch id how to return the result and display in the TextBox.

 

Please help me. Thanks in advance
