Hi All
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

Text value not changing when new value on DropDownList selected
Hi,
I am looking for assistance on how to correctly post events when a new item is selected on a drop down list.
My drop down list has autopostback enabled and a sub routine associated with SelectedIndexChanged. This routine is activated when another entry in the drop down list is selected, however, the value is not changed and the drop down list returns to the originally selected value.
For example, if I have 2 values in my drop down list, 0 and 1, and 0 is the currently selected value. Selecting 1 will trigger the event but the drop down list will return to displaying 0 as the selected ...
