View 4 RepliesWeb Forms :: Validate Control A Depending On If Control B Has Any Value (diff Types)?
Sep 3, 2010I've ready everything I can find on the built-in validators but can't figure out how to do the sort of validation I need on theclient-side (I can do it on the server-side). Business rule I want to enforce (review the gridview snippet below) is if user checks the CheckBox_EditLifeCycleRpt control but doesn't enter a value in the TextBox_LifeExpectancy control then the validation should fail.
[Code]....
Like I said I can get this done on the server-side but thought it would be a good opportunity to learn how to use one of the compare validators. Also (FYI) I'm not too good at authoring Javascript but I can copy/modify other people's code fairly well.

C# - Validate Dropdownlist Selectedvalue Against A List From Static Property?
Oct 4, 2010I am using javascript to validate user input on my aspx page. I am easily able to validate textboxes and dropdown list for differenet scenarios.
Now, on one of my dropdown lists (for country), I need to check if it is an allowed country or not for a particular service. I have stored the valid country list in a static property. Is there a way to validate my dropdownlist selected value against that static property?
function validateService(source, args)
{
var country = document.getElementById('<%= ddDestCountry.ClientID %>');
var service = document.getElementById('<%= ddService.ClientID %>');
// Get allowed country list from my static class
var countryList = document.getElementById('<%= StaticProperties.EUCountryList %>');
if (service.value == "P")
{
// I want to do something like this
if (!countrylist.Contains(country.value))
{
args.IsValid = false;
}
else {
args.IsValid = true;
}
}
return;
}
Update(Additional Information): The static property is read-only so it cannot be tampered with from the page.
