validation control

i have a 2 combobox and a 1 textbox and a search button

1) country combobox
2) state combobox
3) textbox

when user click on search button without entering anything in the textbox then i'm inforcing user to enter (1) country and (2) city name (first 3 characters) which works great but i have a new requirement:

when the user select country = "United States" then i have to make sure user select

1)Country
2)State
3) city name (first 3 characters)

how do i do that?

Hi!

add Item "NONE" to your state combobox for none USA countries ....
and add these lines to search button onclick event =>

if (countrycombo.Items.Item[countrycombo.SelectedIndex].ToString = 'United States') and (statecombo.Items.Item[statecombo.SelectedIndex].ToString <> 'NONE') and (sizeof(textbox1.text) >= 3 ) then
{goto next page}
