How Can add I selected value of DropDownList inside a Repeater to the listbox control in ASP.Net RRS feed

  • Question

  • How can I get the value of the selected item inside the repeater object that I filled from the database, again in the dropdownlist object that I filled from the database?

    How can I transfer the values ​​of the items I selected from these dropdownlist objects to a listbox?

    Thank you...
