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}

Hi,

   In your case the best way should be using a CustomValidator in order to make your own definitions of the validation strategy and so you sould implement something like this:

      - ASPX side

         <asp:CustomValidator id="CustomValidator1"
            ControlToValidate="cboCountry"
            Display="Static"
            ErrorMessage="Invalid information selected"
            ForeColor="green"
            Font-Name="verdana"
            Font-Size="10pt"
            OnServerValidate="ServerValidation"
            ClientValidationFunction="ClientValidate"
            runat="server"/>

            <script language="javascript">
                void ClientValidate(source, argument)            
                {
                     object cboCountry = document.GetElementById('cboCountry');
                     object cboState = document.GetElementById('cboState');
                     object txtCityName = document.GetElementById('txtCityName');

                     arguments.IsValid = (cboCountry.selectedIndex != 1 && cboCountry.value == 'United States' && cboState.selectedIndex != -1 && Trim(txtCityName).length > 0);
                }

            </script>

        - Code-behind

           void ServerValidation(object source, ServerValidateEventArgs args)
           {
                 args.IsValid = (cboCountry.SelectedIndex != -1 && cboCountry.SelectedValue.equals("United States") && cboState.SelectedIndex != -1 && txtCityName.Trim().length > 0);
           }


     This should do it.
