This involves a form with 2 dropdown lists and other fields for user to fill.
dropdownlist 1 say countries of the world
dropdownlist 2 is cities in all the countries in the world
when dropdownlist 1 is used to select a country, dropdownlist 2 is reloaded via autopostback event in list1 to show only cities in the selected
country in list1, user can then select a city from list 2 and it would always match correct country. so far so good
When I try to save the form to database, dropdownlist 1 gives me the correct value, but dropdownlist 2 always gives me...Populate second DropDownList values based on first DropDownLists "SelectedValue" when FormView is in Edit Mode.
My FormView is getting its detail based on the selection in the Master Gridview control.The form subsequently loads its data, and when in edit mode it displays 2x DropDownLists. One is "Country", and the other is "State". Naturally the second DDL will depend on what the parent item is in the first DDL.I am hoping to find this so that I can preload the correct items in the 2nd DDL. I am hoping to accomplish this with as little code as possible, as I am using StronglyTyped DataSets and ObjectDataSource.cheers
