Return dropdownlist to initially selected value

Question

I'm creating a create-read-edit-delete interface.

I have a dynamically populated dropdownlist , ddl_Status which on page load is set to select a particular value. The dropdownlist is then disabled.

If the user clicks "Edit" then I enable the dropdownlist. The user can then change the selection.

If the user clicks "Cancel" I want to return the dropdownlist to it's initial selection and then disable it. If I use ddl_Status.SelectedValue I get the value that the user has selected.

In javascript I would use ddl_Status.defaultValue but I can't find an equivalent in .NET. I'm considering using a hidden field value to store the initial value, but this just seems clumsy.

Answer 1

填充下拉列表时，当用户单击“取消”时，将默认值存储在asp隐藏字段（hdn_DefaultValue）中：ddl_Status.selectedValue = hdn_DefaultValue。

Answer 2

You could store ddl_Status.SelectedIndex in a variable right after loading the page and restore it every time the user clicks "Cancel". Of course this only works if there aren't any changes made to the items.
